The SHiP Experiment - Current Status & Test Beam Results — •Annika Hollnagel — Johannes Gutenberg-Universität Mainz
SHiP has been proposed as a general-purpose fixed-target facility at the CERN SPS North Area, with the start of data taking scheduled for 2026. Consisting of a two-fold detector, it combines the Search for Hidden Particles (SHiP), such as Heavy Neutral Leptons (HNL) and light dark matter, with studies of tau neutrino physics. An additional third detector would enable research on Lepton Flavour Violation.
The impact of the high-intensity 400 GeV/c proton beam on the hybrid target may create HNL via the decay of heavy mesons and other weakly interacting particles of masses m 10 GeV/c2. After a hadron absorber and an active muon shield, these particles are expected to decay inside a large vacuum vessel which is followed by a magnetic spectrometer and a calorimeter. To discriminate against external particle interactions, the decay vessel will be covered by the Surrounding Background Tagger (SBT).
Currently in the R&D phase, several studies have already been performed at the CERN test beam facilities. These include measurements of muon flux and charm production using a replica SHiP target exposed to the SPS proton beam, as well as performance tests of prototype segments for the Liquid Scintillator SBT wrt. particles of various type and energy.
