Commissioning of a prototype for the SHiP Spectrometer Straw Tracker — •Morten Henken, Felix Bergholz, Daniel Bick, Stefan Bieschke, Caren Hagner, and Walter Schmidt-Parzefall — Institut für Experimentalphysik, Luruper Chaussee 149, 22761 Hamburg

The SHiP (Search for Hidden Particles) experiment is a proposed general purpose beam-dump experiment to be located at the CERN SPS North Area. It is designed to search for hidden particles at the intensity frontier as well as to study tau neutrino physics, utilizing the SPS’s 400 GeV proton beam.

The SHiP hidden sector detector is designed to detect the decay products of hidden particles decaying inside it’s ∼50 m long vacuum decay vessel. A crucial part is the determination of the trajectory and the momentum of charged particles produced in these decays. This is the purpose of the Spectrometer Straw Tracker (SST), consisting of roughly 16000 straw tubes, each one 5 m long and 2 cm in diameter.

A prototype, consisting of four straw tubes, has recently been set up at Hamburg University. The status of the commissioning and first results will be presented.
