Abstract
We propose a gamma-ray burst detector (GRB) detector combining the silicon drift detector (SDD) array and scintillators with broadband X-ray and gamma-ray coverage (0.5-1000 keV or more), high energy resolution (2-10%) and high time resolution (~μs) in space. To realize such compact high-performance detector without photomultiplier tubes, we constructed proto-type model using KETEK SDD with a detection area of 1 cm2 and BGO crystal. Signals from both detectors are clearly separated by the double integration method. The detector shows a very good performance. Obtained FWHM energy resolution was 191 eV at 5.9 keV in the SDD, while 6.5% at 662 keV in the BGO at −30 degree C. Evaluation of the 7 channel SDD array and development of analog ASIC for its readout are also presented.
