Abstract

The ASTRO-E hard X-ray detector utilizes GSO(Gd₂SiO⁵:Ce 0.5% mol)-BGO(Bi₄Ge₃O₁₂) well-type phoswich counters [1] in compound-eye configuration to achieve an extremely low background level of about a few times 10^-5 counts s^-1 cm^-2 keV^-1. The GSO scintillators placed at the bottom of the BGO well observe photons in the energy range 30-600 keV. To cover the lower energy range of 10-60 keV, silicon p-i-n diodes of 2 mm in thickness and 21.5×21.5 mm² in size were newly developed and placed in front of the GSO scintillators. The p-i-n diode exhibits complex spectral responses, including subpeak and low energy tail components. To examine the origin of these components, we measured the spatially resolved response of the p-i-n diode and confirmed that the subpeak and the low energy tail are related to the electrode structures and electric fields in the p-i-n diode, respectively.
