Abstract:
A balloon-borne multitechnique large area experiment consisting of 2 co-aligned detectors (3200 cm2 NaI and 1800 cm2 multiwire proportional counters), is described, which is capble of producing observations of the hard X-ray sky with very high sensitivity and good spectral resolution over the whole operative range (15–300 keV).
