We have selected four widely different flares from the early period of operations of the Hard X-Ray Imaging Spectrometer (HXIS) on SMM to illustrate the characteristic imaging properties of this experiment. For the small flare of April 4, 1980, we de

A new position sensitive detector system has been developed for the Hard X-ray Imaging Spectrometer launched aboard the NASA Solar Maximum Mission. The instrument operates in the energy range 3.5-30 keV. The Xe-gas filled detector system consists of

A MWPC read-out system is described that determines the position of a photon interaction by calculating the center of gravity of the charge induced in sense wires. The width of the charge induction is determined to distinguish photon interactions fro

We report the discovery of hard X-rays from the region of the supernova SN1987A in the Large Magellanic Cloud. The observations were made from the Mir-Kvant observatory 'Rontgen'. Hard X-rays were first observed on 10 August 1987 and SN1987A then bec

SAX will contain six instruments of which two will be Wide Field X-ray Cameras. Their design is based on the coded mask principle, mask and detector size are equal. We argue that this 'simple' camera design has certain advantages compared with the 'o

X-ray imaging of the limb event of 1980 April 30 shows that the flaring involved two distinct components: a pointlike component, which was the source of the initial hard X-ray burst and an extensive tongue reaching some 30,000 km above the limb. The
