Abstract: (Springer)
Approximately one million antiprotons have been captured in a large Penning trap at the Low Energy Antiproton Ring at CERN. These antiprotons have subsequently been cooled by electron cooling. This has opened new discussions of the possible use of ultra-low energy antiprotons for nuclear, atomic, and gravitational physics. For most of these experiments, it will be necessary to extract the antiprotons from the trap in a continuous or bunched beam, allowing the timing structure to be used for post-acceleration schemes or as a time tag for the subsequent measurements. We have designed an extraction scheme to accomplish this and have tested portions of it using a smaller Penning trap loaded with protons. First results in generating a time-correlated beam of particles from a Penning trap are presented.References(10)
