The Pair Spectrometer
The pair spectrometer consists of the converter, the dipole magnet and two types of scintillator detectors: 290 high-granularity hodoscope and 16 low-granularity counters (PSC), which are used to detect e+e- pairs produced in the converter by a beam photon. The converter accommodates up to 3 thin foil targets and a wire, which will be used to study the profile of the photon beam. The magnet will be operated at 1.8 T field. Light from scintillators is detected by SiPMs and Hamamatsu H7415 assemblies for the hodoscope and PSC, respectively.
