Remote Antiproton Sources

Antiprotons are well on their way to becoming a standard laboratory commodity. Heavy utilization of LEAR is ushering in a new era where p´s achieve their logical potential, equal to that of e-, e+, H-, as controlled probes and experimental building blocks. The uniqueness and usefulness of p´s for studies at low (table top) energies is well documented. The main stumbling block to universal pursuit of such studies is the overhead of p production. The stablility of the p thus makes cogent an investigation of possibilities and limits to transporting p´s in quantity. I will base my discussion on LEAR as the source of p´s for bottling, since it is the only concrete example to work with at present. Two other lines of contemporary research then, largely in atomic physics, pioneered b Dehmelt and collaborators, aimed at precision studies o clouds of, or single e±, p±, or ions in larqe storage time traps. Second, there is work, experimental and theoretical, from the plasma physics tradition aimed at characterizing non neutral plasmas.
