The TS93 instrument was flown from Fort
Sumner, New
Mexico, on 1993 September 8 at a constant altitude of 36 km at an
average depth of 4.5 g cm-2 of residual atmosphere for a
period of 25 hr.
Two completely new instruments, a transition radiation
detector
and a silicon-tungsten imaging calorimeter, were added to the magnet
spectrometer
already flown. These two detectors provided a proton rejection factor
better
than 3 10 4.
