概要

• 論文の詳細を見る

• We have developed a new kind of phoswih counters (the well-type phoswich counter) that is capable of detecting very low flux hard X-rays/gamma-rays (60-800 keV) from astronomical object. We flew the first prototype detector system (Welcome-1) from Cachoeira Paulista, Brazil in November 1990. The objective was to detect ^<57>Co (122,136keV) and continuum emission from SN1987A. The background spectrum taken at an altitude of 4g/cm^2 indicates that the 3σ sensitivity reaches ∿a few×10^<-6>/cm^2/s/keV and ∿10^<-4>/cm^2/s by 10^4s observation for the continuum spectrum and line spectrum respectively.
