Antimatter Containment |
|||||
Antimatter
has been a staple of science fiction since its discovery in the early
1930s. The subatomic constituents of antimatter, positrons and
antiprotons, have been used in science for a variety of purposes. In
solid state physics, positrons (antielectrons) are used to probe the
structure of solids, while particle physicists collide antiprotons and
protons to study the fundamental properties of matter. Only recently
have antiprotons and positrons been combined to form an antihydrogen atom.
Since then, there has been considerable interest in developing traps that
could simultaneously confine both antiprotons and positrons to form
collections of antihydrogen atoms. There is also a continuing interest
in developing better traps for confining single-species antimatter plasmas
(i.e. positrons or antiprotons). In this talk, the principles used in
trapping single species antimatter plasmas will be examined. Proposed
traps to simultaneously confine both positrons and antiprotons will also be
discussed. The talk will end with a brief exposition of the work being
done here at Mercer in this area. |
