Abstract
A supersonic gas-jet target for investigations of the detailed collision dynamics in fast ion-atom collisions by means of recoil-ion-momentum spectroscopy has been constructed for insertion into the heavy-ion storage ring CRYRING, situated at the Manne Siegbahn Laboratory, Stockholm University. The aim is to create a target with a density of 1012 cm-3 and a temperature of less than 10 mK (for the case of a He target) without seriously affecting the excellent vacuum conditions of CRYRING. The gas target will become a part of the storage ring, and hence fast beams of protons, highly-charged ions, and molecular ions will be available as projectiles. Here we present test results for parts of the system. These all indicate that the design criteria will be fulfilled.
