How Far Away is Fusion? Unlocking the Power of the Sun

          

How Far Away is Fusion? Unlocking the Power of the Sun

Δημοσιεύτηκε στις 27 Μαΐ 2017

The
Sun uses its enormous mass to crush hydrogen into fusion, releasing
enormous energy. How long will it be until we’ve got this energy source
for Earth?

I’d like to think we’re smarter than the Sun.

Let’s
compare and contrast. Humans, on the one hand, have made enormous
advances in science and technology, built cities, cars, computers, and
phones. We have split the atom for war and for energy.

What has
the Sun done? It’s a massive ball of plasma, made up of mostly hydrogen
and helium. It just, kind of, sits there. Every now and then it burps
up hydrogen gas into a coronal mass ejection. It’s not a stretch to say
that the Sun, and all inanimate material in the Universe, isn’t the
sharpest knife in the drawer.

And yet, the Sun has mastered a
form of energy that we just can’t seem to wrap our minds around: fusion.
It’s really infuriating, seeing the Sun, just sitting there,
effortlessly doing something our finest minds have struggled with for
half a century.

Why can’t we make fusion work? How long until we can finally catch up technologically with a sphere of ionized gas?

The
trick to the Sun’s ability to generate power through nuclear fusion, of
course, comes from its enormous mass. The Sun contains 1.989 x 10^30
kilograms of mostly hydrogen and helium, and this mass pushes inward,
creating a core heated to 15 million degrees C, with 150 times the
density of water.

It’s at this core that the Sun does its work,
mashing atoms of hydrogen into helium. This process of fusion is an
exothermic reaction, which means that every time a new atom of helium is
created, photons in the form of gamma radiation are also released.

The
only thing the Sun uses this energy for is light pressure, to
counteract the gravity pulling everything inward. Its photons slowly
make their way up through the Sun and then they’re released into space.
So wasteful.

How can we replicate this on Earth?

Now
gathering together a Sun’s mass of hydrogen here on Earth is one option,
but it’s really impractical. Where would we put all that hydrogen. The
better solution will be to use our technology to simulate the conditions
at the core of the Sun.

If we can make a fusion reactor where
the temperatures and pressures are high enough for atoms of hydrogen to
merge into helium, we can harness those sweet sweet photons of gamma
radiation.

The main technology developed to do this is called a
tokamak reactor; it’s a based on a Russian acronym for: “toroidal
chamber with magnetic coils”, and the first prototypes were created in
the 1960s. There are many different reactors in development, but the
method is essentially the same.

A vacuum chamber is filled with
hydrogen fuel. Then an enormous amount of electricity is run through the
chamber, heating up the hydrogen into a plasma state. They might also
use lasers and other methods to get the plasma up to 150 to 300 million
degrees Celsius (10 to 20 times hotter than the Sun’s core).

Superconducting
magnets surround the fusion chamber, containing the plasma and keeping
it away from the chamber walls, which would melt otherwise.

Once
the temperatures and pressures are high enough, atoms of hydrogen are
crushed together into helium just like in the Sun. This releases photons
which heat up the plasma, keeping the reaction going without any
addition energy input.

Excess heat reaches the chamber walls, and can be extracted to do work.

The
challenge has always been that heating up the chamber and constraining
the plasma uses up more energy than gets produced in the reactor. We can
make fusion work, we just haven’t been able to extract surplus energy
from the system… yet.

Compared to other forms of energy
production, fusion should be clean and safe. The fuel source is water,
and the byproduct is helium (which the world is actually starting to run
out of). If there’s a problem with the reactor, it would cool down and
the fusion reaction would stop.

The high energy photons released
in the fusion reaction will be a problem, however. They’ll stream into
the surrounding fusion reactor and make the whole thing radioactive. The
fusion chamber will be deadly for about 50 years, but its rapid
half-life will make it as radioactive as coal ash after 500 years. Do
you know coal ash is radioactive?

Unlocking the Secrets of Nearby Exoplanets with the TESS Mission - Georg.

Δημοσιεύτηκε στις 16 Δεκ 2016

Dr. Ricker is the PI of the TESS Mission which will explore nearby stars for exoplanets.

The
Transiting Exoplanet Survey Satellite (TESS) will discover thousands of
exoplanets in orbit around the brightest stars in the sky. In its
two-year prime survey mission, TESS will monitor more than 200,000
bright stars in the solar neighborhood for temporary drops in brightness
caused by planetary transits. This first-ever spaceborne all-sky
transit survey will identify planets ranging from Earth-sized to gas
giants, around a wide range of stellar types and orbital distances.

TESS
stars will typically be 30-100 times brighter than those surveyed by
the Kepler satellite; thus, TESS planets will be far easier to
characterize with follow-up observations. For the first time it will be
possible to study the masses, sizes, densities, orbits, and atmospheres
of a large cohort of small planets, including a sample of rocky worlds
in the habitable zones of their host stars.

An additional data
product from the TESS mission will be full frame images (FFI) with a
cadence of 30 minutes. These FFI will provide precise photometric
information for every object within the 2300 square degree instantaneous
field of view of the TESS cameras. These objects will include more than
1 million stars and bright galaxies observed during sessions of several
weeks. In total, more than 30 million objects brighter than magnitude
I=16 will be precisely photometered during the two-year prime mission.
In principle, the lunar-resonant TESS orbit could provide opportunities
for an extended mission lasting more than a decade, with data rates in
excess of 100 Mbits/s.
An extended survey by TESS of regions
surrounding the North and South Ecliptic Poles will provide prime
exoplanet targets for characterization with the James Webb Space
Telescope (JWST), as well as other large ground-based and space-based
telescopes of the future.
A NASA Guest Investigator program is
planned for TESS. The TESS legacy will be a catalog of the nearest and
brightest main-sequence stars hosting transiting exoplanets, which
should endure as the most favorable targets for detailed future
investigations.
TESS is currently targeted for launch in late 2017 as a NASA Astrophysics Explorer mission

Stellar occultations of planetary rings: from Palomar to Cassini - Phil ...

Δημοσιεύτηκε στις 10 Φεβ 2017

Chance
observations of stars as they pass behind planets have provided some of
our most valuable data on the structure of planetary ring systems,
beginning with the discovery of the uranian rings with the Kuiper
Airborne Observatory in 1977. As a graduate student at Caltech in the
70s, I became involved first in studies of the dynamically-curious
uranian rings at Mount Palomar and later in unraveling the story of the
even more baffling ring arcs of Neptune. I will review some of the
highlights of this early work, which led to my current involvement in
the Cassini mission at Saturn, observing stellar occultations with the
VIMS (Visual and Infrared Mapping Spectrometer) instrument. Over 150
such occultations have been observed over the past 12 years, leading to
the discovery and/or characterization of such novel features as
self-gravity wakes, numerous density and bending waves, eccentric and
inclined ringlets, `normal modes’ on gap edges and instances of `viscous
overstability’ in denser regions of the rings. Our ring observations
have also provided insights into the internal structure of Saturn
itself.

Origins of Structure in Planetary Systems  - Ruth Murray-Clay (SETI Talk...

Δημοσιεύτηκε στις 24 Φεβ 2017

Observations
confirm that planet formation is a ubiquitous process that produces a
diversity of planetary systems. However, a class of solar system analogs
has yet to be identified among the thousands of currently known planets
and candidates, the overwhelming majority of which are more easily
detectable than direct counterparts of the Sun's worlds. To understand
whether our solar system’s history was unusual and, more generally, to
properly characterize the galactic population of extrasolar planets, we
must identify how differences in formation environment translate into
different planetary system architectures. In this talk, Dr. Murray-Clay
will consider our solar system in the context of theoretical advances in
planet formation driven by the study of extrasolar planets. Along the
way, she will discuss several examples of physical processes operating
at different stages of planet formation that imprint observable
structures on the dynamical and compositional demographics of planetary
systems.

The
all-sky TESS mission will soon revolutionize our view of planets
transiting the nearest, brightest stars to the Sun, just as the
four-year survey by NASA's Kepler mission transformed our understanding
of exoplanet demographics. Using the repurposed Kepler spacecraft, the
ongoing K2 mission provides a natural transition from Kepler to TESS in
terms of sky coverage, survey duration, and intensity of ground-based
follow-up observations. For the past three years I have led a large,
multi-institutional team to discover, follow up, validate, and
characterize hundreds of new candidates and planets using data from K2. I
will highlight some of our key results from the first two years of K2
data, and will conclude with a discussion of the path forward to future
exoplanet discovery and characterization.

We
know there’s dark matter, and there are galaxies, but are there
galaxies entirely made up of dark matter? Astronomer Sarah Pearson joins

One
of the things I love about astronomy is how it’s rapidly changing and
evolving over time. Every day there are new discoveries, and
advancements in theories that take us incrementally forward in our
understanding of the Universe.

One of the best examples of this
is dark matter; mysterious and invisible but a significant part of the
Universe and accounting for the vast majority of mass out there.

It
was first theorized almost 100 years ago when astronomers surveyed the
total mass of distant galaxy clusters and found that the visible mass we
can see must be just a fraction of the total material in the clusters.
When you add up the stars and gas, galaxies move and rotate in ways that
indicate there’s a huge halo of invisible matter surrounding it.

Some
of the best evidence came from Vera Rubin and Kent Ford in the 60s and
70s, when they measured the rotational velocity of edge-on spiral
galaxies. They estimated that there must be about 6 times as much dark
matter as regular matter.

Dark matter became a serious mystery in
astronomy, and many observers and theorists have spent the last half
century trying to work out what it is.

And dark matter hasn’t
given up its secrets easily. Originally, astronomers thought it might
not actually be invisible mass, but a misunderstanding of how gravity
works at the largest scales.

But over the last few decades,
techniques have been developed, using the gravity of dark matter itself
to measure how it bends light from more distant objects. Astronomers
don’t know what dark matter is, but they’re able to use it as a
telescope. Now that’s impressive.

They’ve found amazing features
in the dark matter web out there, vast walls and filaments defining the
largest scale structures in the Universe. Clusters where dark matter and
its gas have been separated from each other.

Remember, we are at
the cutting edge of this mystery, and you’re watching it unfold in real
time. 25 years from now, I’m sure we’ll look back at our quaint
attempts to understand dark matter.

One of the most interesting
questions I have right now is: could there be dark matter galaxies?
Completely invisible to our eyes, but able to interact through gravity?

Of
course, in times like this, I like to bring in a ringer. Someone who
has dedicated their life to the study of these questions.

And
today, I’ve got with my Sarah Pearson, a graduate student in astronomy
at Columbia University and the host of “Space with Sarah”. Sarah studies
the formation and interactions of dwarf galaxies surrounding the Milky
Way to understand how galaxies built up at the earliest times in the
Universe and form the large galaxies we see at present day.

Sarah, welcome to the Guide to Space:

Sarah: Hi Fraser, thanks.

Fraser: Can you talk a little bit about how astronomers map out the distribution of dark matter in the Universe?

Sarah:
Yes, definitely. So that is a hard question, as you just explained, we
don’t see the dark matter. But one assumption about the Universe we live
in is that the light matter or baryonic matter. For example, what you,
me and stars consist of, and also galaxies, kind of trace out where the
dark matter is located.

So one assumption is that the light
matter follows the dark matter. In that way we can actually map out to
huge distances, kind of how galaxies and clusters of galaxies are
located in our Universe. And we imagine that the dark matter structure
is somewhat similar.

And also recently, very large scale
structure simulations of our own Universe have addressed this by kind of
starting out with an almost uniform distribution of dark matter in the
very early Universe. And what they see is when they let the Universe
evolve in time, for example, when the Universe is expanding, you kind of
have these dark matter clumps forming into galaxies in all these
filaments that you discussed.

You can kind of trace out the
location of dark matter by understanding the expansion of space versus
gravity that creates the galaxies that we see.

The Higgs Boson Explained

             

The Higgs Boson Explained

Δημοσιεύτηκε στις 16 Ιουλ 2012

On
Friday July 13 at noon, faculty and other members of the Physics
Department helped the campus community understand the significance of
discovering the Higgs Boson, the particle that was predicted by Peter
Higgs almost 50 years ago. Mark Richards, Executive Dean of the College
of Letters & Sciences, will host this discussion for the Berkeley
community.
Professors Beate Heinemann, an experimental physicist and a
member of the ATLAS experiment at the LHC in CERN, Switzerland, and
Lawrence Hall, a theoretical physicist and former Director of the
Berkeley Center for Theoretical Physics, explained what the Higgs is,
why it was predicted and how it was proven to exist. They were joined by
panel members Professor Marjorie Shapiro, also a member of the Atlas
experiment, Miller Fellow Josh Ruderman and PhD student and ATLAS member
Louise Skinnari.

An introduction to: Feynman Diagrams

Δημοσιεύτηκε στις 21 Φεβ 2016

An
introduction to: Feynman diagrams. A video version of a talk I gave to
my physics society. This gives a brief explanation of the standard model
and then goes onto some of the basics of constructing simple Feynman
diagrams. I then go through some exampleThe links in the video ars, like
beta minus decay.
This does assume some knowledge of sub-atomic particles.

The dark side of the universe

Δημοσιεύτηκε στις 24 Απρ 2014

Public lecture by Dr Clare Burrage as part of the 2014 Edinburgh International Science Festival.

Billions
of years ago the Big Bang sent everything flying apart. In theory,
gravity should stop galaxies from moving apart and matter should
eventually re-collapse on itself. Surprisingly, we have learnt that
galaxies are actually moving apart with ever-increasing speed. Nothing
in our current knowledge of physics can explain this, but theorists are
developing a solution: dark energy. Roughly 70% of our universe is
comprised of dark energy and yet so little is known about it, but
satellite and laboratory experiments are under way. Join Dr Clare
Burrage as she reveals the nature of dark energy, how it affects other
matter in the universe, and what plans we have for observing this
mysterious force.

5:30 pm — 7:00 pm on Friday 18 April 2014 at National Museum of Scotland, Edinburgh.

The asymmetric universe

           

The asymmetric universe

Δημοσιεύτηκε στις 5 Φεβ 2014

Michael Faraday Prize and Lecture by Professor Frank Close OBE, University of Oxford.

Modern
scientific theory describes a perfectly symmetrical universe. A
universe in which matter is destroyed within an instant of its
appearance and where nothing we now know could ever have happened. Human
life itself seems to be lopsided, as the spherical embryo is
transformed into a highly structured being with its internal organs
mirrored asymmetrically. This talk explores the profound role of
asymmetry in nature, and the role of its agent - the Higgs Boson - in
creating a universe fit for life.

The Royal Society Michael
Faraday Prize is awarded annually to the scientist or engineer whose
expertise in communicating scientific ideas in lay terms is exemplary.
Professor Frank Close OBE was presented the award for his excellence in
science communication.

6:30 pm -- 7:30 pm on Tuesday 28 January 2014 at The Royal Society, London.
