The LYCCA detector module — •Andreas Wendt1,2, Peter Reiter1, Kerstin Geibel1, Christoph Goergen1, Gheorghe Pascovici1, Dirk Rudolph3, Pavel Golubev3, Jürgen Gerl4, and Robert Hoischen4 — 1Institut für Kernphysik, Universität zu Köln, Germany — 2Frankfurt Institut for Advanced Studies (GP-HIR@FIAS), Germany — 3Department of Physics, Lund University, Sweden — 4GSI, Darmstadt, Germany
The Lund-York-Cologne Calorimeter Array LYCCA will be employed for future PRESPEC and HISPEC γ-ray spectroscopy experiments at the GSI/FAIR accelerator facility for reaction product identification after a secondary target at the focal plan of the FRS/SUPER-FRS.
The modular array will comprise plastic or diamond detectors for TOF measurement and ΔE-E telescopes of DSSSD and CsI detectors. The individual modular detector consists of 32x32 Si strip detectors and 9 CsI scintillators. A new developped preamplifier is used for energy measurement up to 5 GeV and fast timing in the subnanosecond time range. These new preamplifiers achieve an electronic energy-resolution of 10keV and obtain fast signal rise times below 20ns. Expected energy-resolution in combination with DSSSD is about 45-50 keV at 5-6 MeV alpha-energies.
First test results from two detector units were obtained using alpha-sources and protons from the Cologne tandem accelerators.
Supported by the German BMBF (06KY205I).
