Pictured is the Hall C detector for the High Momentum Spectrometer (HMS). Contained in a concrete shield house, this detector is used for particle identification after the beam hits the target and the scattered particles are focused onto this detector . The detector contains several instruments that measure different elements of the particles including: drift chambers, hodoscopes, and gas and lead-glass Cerenkov detectors.
