Multiwire proportional chamber spectrometer for the CERN intersecting storage rings

Abstract The design, construction, and performance of a multiware proportional chamber (MWPC) system (∼10 k wires) constructed for use at the CERN Intersecting Storage Rings (ISR) is described. This system employs hybrid integrated circuity for pulse detection and storage, and is read out via a CAMAC compatible system. The chambers plus two large-aperture magnets with accompanying scintillation and Cherenkov counters form a versatile multiparticle spectrometer system which has been used to investigate particle systems produced near 0° at the CERN ISR.
