Abstract
A high-resolution detector array has been developed for the measuremen t of momenta of charged and uncharged particles via the time-of-flight method. This spectrometer represents one detector arm of a system use d to study the photoabsorption mechanisms of (gamma, NN) and (gamma, p i N) reactions. It is comprised of 112 plastic scintillators (NE110) o f dimensions 5 x 20 x 300 cm(3) with a photomultiplier attached to eac h end. A mean time resolution of less than or similar to 400 ps (FWHM) and a position resolution of less than or similar to 6 cm have been a chieved. The modularity and flexibility of the array encouraged its us e in other electron-and photon-induced reaction measurements.
