Testing prototype Micron X5 silicon-strip detectors for the R3B setup — •Sonja Storck¹, Ina Syndikus^1,2, Dominic Rossi¹, and Thomas Aumann^1,2 for the R3B collaboration — ¹Institut für Kernphysik, TU Darmstadt, Darmstadt, Deutschland — ²GSI Helmholtzzentrum für Schwerionenforschung, Darmstadt, Deutschland

With the R3B (Reactions with Relativistic Radioactive Beams) setup at GSI in Darmstadt, it is possible to perform kinematically complete measurements with relativistic radioactive beams. In order to identify the incoming and outgoing particles, various detector systems are necessary. Among other systems, silicon-strip detectors employing the resistive charge division are used to measure the positions and the energy loss of charged particles before and after the target.

A new prototype of a double-sided silicon-strip detector, Micron X5, was tested in beam during a beam time at GSI in 2018 with ⁴⁰Ar and ¹⁰⁷Ag beams. The detectors have 32 strips on each side which are arranged perpendicularly to each other to give an x and y position in the same detector. The strips have a resistive surface and are read out at the ends of each strip. The detectors were tested regarding the energy and position resolution.
