An accumulator/compressor ring for Ne+ ions
The primary goal of the High Energy Density Physics (HEDP) program is to create an extremely bright ion beam at low duty cycle. For example, a typical set of parameters is: (1) Particle type = Ne{sup +}; (2) Ion energy = 20.1 MeV; (3) One ion pulse = 1 {micro}C, 1 ns, 1 mm{sup 2}; and (4) Repetition rate = 1 Hz. This would give a volume density of {approx}10{sup 12} particles/mm{sup 3}, which is several orders of magnitude higher than any existing proton machines (typically 10{sup 8}-10{sup 9} particles/mm{sup 3}, see reference [1]). On the other hand, however, the beam power is very low. At 20.1 MeV, 1 {micro}C and 1 Hz, one has: Beam power = 20.1 W. This leads to the following observation: In an HEDP machine, beam loss is a non-issue. This has important implication in the machine design. The machine is fundamentally different from those high power ({approx} MW) proton machines such as PSR, ISIS, SNS, RIA, GSI and JPARC, of which the machine design is dominated by beam loss control. A second observation is that, as it stands now, the HEDP program has limited funds (several $M). The hardware design needs to be as simple and realistic as possible.
