A high-pressure parallel-grid gas scintillation proportional counter for high-energy X-ray astronomy

Summary We present preliminary results on a new detector for X-ray astronomy sensitive in the energy range from 3 to 120 keV. The detector can be implemented either as a narrow-field instrument (∼1 degree field of view) or as wide field camera (30×30 degree field of view). This detector with its large area, good energy resolution and background rejection represents a valid option to the present generation of instruments for high-energy X-ray astronomy. Paper presented at the 2° Convegno Nazionale di Fisica Cosmica, held at L'Aquila, 29 May–2 June 1984.
