Plastic Scintillator Detectors for the Study of Transfer and Breakup Reactions at Intermediate Energies

摘要

The detection of light particles associated with projectile like fragments can be used to separate transfer and breakup reactions provided the detectors cover a large solid angle. Three detection systems are described: (1) a pi detector in the shape of a cube, 20 cm on a side, (2) a X-Y position sensitive delta E-E detector having an area of 20 x 20 cm exp 2 , and (3) a multi-element detector consisting of eight position sensitive strips. The latter two detectors are of the phoswich type having the thin element of NE102 (tau = 2.5 ns) and the thick element of NE115 (tau = 225 ns). The performance characteristics of the three detectors are described. 6 references, 13 figures. (ERA citation 10:024269)
