A Laser Ablation Ion Source for the FRS Ion Catcher — •Ann-Kathrin Rink1, Timo Dickel1,2, Jens Ebert1, Hans Geissel1,2, Wolfgang Plass1,2, Martin Petrick1, Sivaji Purushothamen2, Pascal Reiter1, and Christoph Scheidenberger1,21Justus-Liebig Universität Giessen — 2GSI Darmstadt

The FRS Ion Catcher was developed to serve as test bench for the low energy branch of the Super FRS to slow down exotic nuclei and prepare them for further measurements/ experiments. It consists of a cryogenic stopping cell to thermalise the ions, a diagnostic unit for stopping cell characterisation and various radiofrequency quadrupole structures to guide the ions to the Multiple-Reflection Time-of-Flight Mass Spectrometer for mass measurements, α spectroscopy and isobar separation. To characterise the extraction times of the stopping cell, which is one of the main performance parameters of such a cell, a laser ablation ion source has been develped and tested. This ion source provides a sharply defined starting point of the ions for the extraction time measurement. In the future this source will provide reference ions to calibrate the mass spectrometer for accurate mass measurements.
