The TS93 instrument was flown from Fort
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.
