TS93

TS93 Drawing
The experimental goal of the TS93 experiment was to measure electrons and positrons from 4 to about 50 GeV (The upper value is only limited by exposure factor).
The magnet spectrometer was not changed from the IMAX flight. To separate the electrons and positrons from the protons, two new detectors were installed:

A Transitient-Radiation-Detector built by the University of Bari,Italy. The TRD has 10 layers of carbon fibres each separated by a MWPC.
Instead of the streamer-tube brass-calorimeter used in the MASS2 flight an improved imaging silicon-tungsten calorimeter (also built in Italy).
The instrument was launched in september 1993 from Ft. Sumner, NM and had 25 hours float.
