HI-TREX: Compact, high resolution particle detection system for ISOLDE — Roman Gernhäuser, •Sergei Golenev, and Robert Neagu for the MINIBALL-Collaboration — Technische Universität München, Germany

HI-TREX is a particle detection setup, developed for the HIE-ISOLDE facility at CERN, optimized for transfer reactions using radioactive ion beams. HI-TREX is based on a very thin double-sided silicon strip detector (DSSSD), high-resolution front-end electronics based on SKIROC ASICs, and a newly developed, custom made, FPGA based GEneric Asic Readout board GEAR for the TRB data acquisition system.
A full system test with an array of four detectors in a two arm geometry was performed at the Bronowice Cyclotron Center in Krakow using proton beams with energies ranging from 80 to 200 MeV.
With ancillary CsI(Tl) scintillation detectors behind the setup and a plastic fiber target a full 4-momentum reconstruction of the 12C(p,2p) reactions is performed. We will present first results on calibrations, the energy resolution and the event correlations to determine absolute efficiencies of the new detector elements.
