A Straw Tracker Prototype for SHiP — •Wei-Chieh Lee, Caren Hagner, and Daniel Bick — Institut für Experimentalphysik, Universität Hamburg, Hamburg, Deutschland

SHiP (Search for Hidden Particles) is a general-purpose beam-dump experiment at the CERN SPS accelerator designed for the search of feebly interacting particles. In this experiment, the spectrometer straw tracker (SST) is located downstream of the hidden sector decay volume, and tracks the decay products of the hidden particles for the reconstruction of the decay vertex, the mass and the impact parameter of these particles. As the main component of the SST, straw tubes function as wire-based gaseous detectors that are robust and have little material budget for the purpose of minimizing multiple scatterings. The University of Hamburg is participating in the design and prototyping of the SST with the goal of optimization of the mechanical stability and the assembly strategy. In this presentation, a straw tracker prototype will be introduced with the plans of its future testing.
