Abstract
Two main aims of the SHiP (Search for Hidden Particles) experiment are the observation of hidden particles and high-statistics study of tau neutrino events. These particles can be produced from the decay of charmed particles in a SHiP hybrid target which is composed of a totally 58-cm long series of TZM slabs followed by Tungsten slabs of the same total length. To achieve the physics goals, we carried out a test experiment with the SHiP target replica using CERN SPS 400 GeV/c proton beam at H4 area in July 2018. A major concern for the test experiment is the precise knowledge of the muon flux and the associated charm production cross section. In this test experiment, RPCs will be used for muon identification and their slope measurements. Recently, we have fabricated gas gaps and strip panels to build 5 trigger RPC modules for the present test experiment. In addition, we constructed a prototype RPC to study the fundamental detector performance using cosmic rays. The current construction of the RPC modules is also as a pilot production for the future SHiP experiment in synergy with the present RPC production for the CMS experiment.
