P. Aspell et al., ENERGY AND SPATIAL-RESOLUTION OF A SHASHLIK CALORIMETER AND A SILICONPRESHOWER DETECTOR, Nuclear instruments & methods in physics research. Section A, Accelerators, spectrometers, detectors and associated equipment, 376(1), 1996, pp. 17-28
New projective prototypes of a scintillator/lead sandwich type samplin
g calorimeter Shashlik with a silicon preshower detector have been con
structed and tested with an electron beam at CERN-SPS. The energy reso
lution is measured to be 8.7%/root E(GeV) in stochastic term, 0.330/E(
GeV) in noise term and 0.5% in constant term. The angular resolution i
s better than 70 mrad/root E(GeV).
