Table-top accelerators make progress |
Table-top accelerators make progress (Sep 29)
http://physicsweb.org/article/news/8/9/17
The prospects for plasma-based particle accelerators have improved
following breakthroughs by independent groups in the UK, US and France.
Acceleration gradients thousands of times higher than those produced in
conventional accelerators have already been demonstrated in
laser-produced plasmas. However, it has only been possible to accelerate
particles over distances of about 1 millimetre and the resulting beams
have been of poor quality with a large energy spread. Now, three groups
of physicists have developed a variety of techniques -- including the
formation of channels and bubbles in the plasma -- to reduce the energy
spread in the beam to just a few percent (Nature 431 535, 538 and 541).

Why don't you post your physics news items to
alt.sci.physics also. It doesn't take extra effort.
