Technical proposal for a two arm photon spectrometer (TAPS)

Creators

Description

A BaF2 scintillation spectrometer for the detection of high-energy photons is proposed. It will be operated in conjunction with particle detectors which provide exclusive triggers and event characterization. The photon detector system comprises 256 individual modules which are combined into 4 arrays of 64 elements each. The individual modules are hexagonal in cross section with an inscribed radius of 29.5 mm and have a length of 250 mm = 12 X0. Neutron-γ separation will be accomplished by time-of-flight and pulse shape analysis, while charged particle discrimination is achieved by additional thin (0.05 X0) plastic scintillation veto detectors in front of the BaF2 elements.
