Positron Moderator Systems
The RGM-1 turnkey positron beam systems, with an output of up to to 107 positrons
per sec., include equipment for producing solid neon moderators, radiation shielding
for sources of up to 150 mCi (22Na), magnetic beam transport, and fixturing for
loading and unloading source capsules with minimum radiation exposure.Detailed specifications for the RGM-1
Compact Positron Penning Traps
Compact two stage traps with high trapping efficiency and positron lifetimes of >1 s can be supplied by FPSI. Longer confinement times (>1000 s) are possible by adding a separate third stage. A variety of options are available including: (a) cryogenically cooled trap electrodes to produce ultra-cold positron plasmas; (b) radial positron plasma compression using rotating electric fields; (c) harmonic potential bunching to produce ultra-short positron beam pulses (<200 ps); and (d) electrostatic optics for extracting the beam from the magnetic field of the trap.
Turn-key Positron Beam Systems
Complete computer-controlled positron beam systems can be supplied by FPSI that include various combinations of the items noted above. A system incorporating many of the items was recently delivered to Professor Allen Mills at the University of California, Riverside.
