H. Ochiishi et al., APPLICATION OF BRAGG-CURVE COUNTERS TO A TARGET MULTIFRAGMENTATION MEASUREMENT, Nuclear instruments & methods in physics research. Section A, Accelerators, spectrometers, detectors and associated equipment, 369(1), 1996, pp. 269-276
We have constructed Bragg-curve counters (BCCs) to detect the intermed
iate-mass fragments (IMFs) emitted during target multifragmentation in
duced by 12-GeV primary protons on Au, Ag targets. An energy resolutio
n of similar to 1.0% and an atomic-number resolution of 2.0% have been
achieved. Long-term stability of the output pulse-heights, which was
necessary for actual IMF measurements, was realized by employing a con
tinuous gas-flow system with a constant pressure.
