Balloon launched on 7/24/1985, from Base di Lancio Luigi Broglio, Trapani, Sicily, Italy
Purpose of the flight and payload description
It is a large-area high-sensitivity hard X-ray telescope, operating in the energy range 15-300 keV and is formed of two different arrays: scintillation detectors (NaI, 5.5-mm thick and actively shielded) with a total area of 2700 cm2 and high-pressure xenon gas multiwire proportional counters with a total sensitive area of 900 cm2.
This detector is mounted on a gondola wich includes an elevation drive system and azimuthal control.
The instrument takes their name from the institutions that made it (MIlano FRAscati SOuthampton) and also is referred in certain balloon literature as the PALLAS gondola. Hence the double title.
No scientific data obtained due to the balloon failure.
