Evaporative cooling of highly charged dysprosium ions in an enhanced electron-beam ion trap

Abstract

The mechanism of evaporative cooling of highly charged ions in an electron-beam ion trap (EBIT) is discussed. Computer simulations of evaporative cooling in superEBIT indicate that with the use of neon, nitrogen, or helium coolants, significant amounts of bare and hydrogenlike dysprosium ions can be trapped indefinitely for the observation of bound-state \ensuremath{\beta} decay.
