HARD X-RAY SPECTROMETER

The instrument uses sixteen cadmium telluride (CdTe) detectors with iridium electrodes that act as Schottky barriers.

Balloon launched on: 5/24/2002 at 6:45 jst
Launch site: Sanriku Balloon Center, Iwate, Japan  
Balloon launched by: Institute of Space and Astronautical Science (ISAS)
Balloon manufacturer/size/composition: Zero Pressure Balloon model B80 80.000 m3
Flight identification number: B80-7
End of flight (L for landing time, W for last contact, otherwise termination time): 5/24/2002 at 17:00 jst
Balloon flight duration (F: time at float only, otherwise total flight time in d:days / h:hours or m:minutes - ): 11 h 45 m
Landing site: A parachute failure caused the instrument to land harder than intended and as a result of the impact resulted partially destroyed.

All onboard instruments performed normally during the flight and successfully observed an M1.2-class solar flare around 15:30 JST.
