M. Ripani et al., CHOICE AND TEST OF THE PHOTOMULTIPLIERS FOR THE LARGE-ANGLE ELECTROMAGNETIC SHOWER CALORIMETER ON THE CLAS DETECTOR AT CEBAF, Nuclear instruments & methods in physics research. Section A, Accelerators, spectrometers, detectors and associated equipment, 406(3), 1998, pp. 403-410
The choice of the photomultipliers for the Large Angle electromagnetic
Calorimeter to be installed on the CLAS detector at CEBAF is reported
. The results of comparative tests on three different types of tubes a
re presented; then the CAMAC-based apparatus that was used to measure
the most relevant parameters of a large number of photomultipliers of
the chosen type is described and results are discussed. (C) 1998 Elsev
