ELECTROSTATIC BOTTLE FOR LONG-TIME STORAGE OF FAST-ION BEAMS

A technique for storage of fast-ion beams (keV) using only electrostat ic fields is presented. The fast-ion trap is designed like an optical resonator, whose electrode configuration allows for a very large field -free region, easy access into the trap by various probes, a simple io n loading technique, and a broad acceptance range for the initial kine tic energies of the ions. Such a fast-ion storage device opens up many experimental possibilities, a few of which an presented.
