New developments in TRImP and RIASH at KVI

Abstract

The status of the TRI mu P facility at KVI is reviewed. Recent results on ion catcher devices are described. A thermo-ionizer for use with alkali and earth-alkali elements is close to completion. Concerning the use of superfluid helium as stopping medium, evidence that second sound pulses can be used to extract ions from the helium surface has been obtained. Based on the observation of highly efficient ion transport in helium, neon and argon gas below about 100 K, we propose the operation of noble gas ion catchers at cryogenic temperatures.</p
