A small-angle large-acceptance detection system for hadrons

The performance of a segmented large-acceptance detector, capable of measur ing particles at small forward angles, is presented. The Small-Angle Large- Acceptance Detector (SALAD), was built to handle very high rates of particl es impinging on the detector. Particles down to a few MeV can be detected w ith it. The position of charged particles is measured by two Multi-Wire Pro portional Chambers while scintillator blocks are used to measure the energy of the detected particle. A stack of thin scintillators placed behind the energy detectors allows for a hardware rejection (veto) of high-energy part icles going through the scintillator blocks. (C) 2000 Elsevier Science B.V.
