Abstract

An ion catcher as presented in this contribution is able to create cooled and very clean singly-charged ion pulses out of a 'hot' beam within a very short period of time. Precision measurements on shortlived radioactive nuclides become possible. This contribution describes experiments with a ²⁵²Cf fission source at the 'gas-cooler' at ATLAS (Argonne Tandem Linac Accelerating System) at the Argonne National Laboratories (ANL), Argonne, USA [1]. The system consists of a gas-cell to stop and thermalize the ions, two extraction radio frequency quadrupole structures (RFQ) to separate the ions from the buffer gas and a buncher RFQ to cool and accumulate the ions. The system and its performance is investigated with two independent measurements. The transported activity was measured to determine the efficiency of the system and time of flight measurements (TOF) were performed to determine the transported masses with respect to the transported activity.
