We have developed high sensitivity, high energy resolution hard X-ray/soft gamma-ray detectors for a wide range of applications. In the energy band where NaI (Tl) has benn used (100keV-1MeV), we developed two new inorganic scintillators (GSO and YAP) with Hitachi Chemical (GSO) and Inst. of Nuclear Physics, Minsk, Belarus (YAP) to practically applicable levels. In the lower energy band (10keV-100keV), we developed thick PIN photodiodes (0.5-1.5mm).These two technologies have been combined in the well-type phoswich counter with PIN diodes proposed for astronomical hard X-ray detection. The detectors has been adopted as an instrument on board a Japanese satellite project Astro-E.The final products have given the following characteristics.GSO, Energy resolution - 7.0%(fwhm)at 662keVYAP, Energy resolution - 5.8% at 662keVlight yield-35% of NaI(Tl)at 552keVSi PIN Photodiode Depletion thickness - 1.5mmEnergy resolution <3.0keVWe then worked on a pulse shape discriminator optimized for our well-type phowich counter. A proto-type circuit was made on a bread-board and tested successfully and the design has been put into an ASIC design of LSI.In the final year of the project, we produce a prototype chip. We are now in the second round designing stage.

我们开发了高灵敏度，高能量分辨率的硬x射线/软伽马射线探测器，用于广泛的应用。在使用NaI （Tl）的能量带（100kv - 1mev），我们与日立化学（GSO）和白俄罗斯明斯克核物理研究所（YAP）共同开发了两种新的无机闪烁体（GSO和YAP），达到了实际适用的水平。在较低的能量带（10kv - 100kev），我们开发了厚PIN光电二极管（0.5-1.5mm）。这两种技术已被结合在用于天文硬x射线探测的带有PIN二极管的井型光电计数器中。该探测器已被日本Astro-E卫星项目采用为仪器。最终产品具有以下特点。GSO，在662keVYAP下能量分辨率- 7.0%(fwhm)，在662keVlight下能量分辨率- 5.8%，在552keVSi PIN光电二极管下NaI（Tl）的产率为35%，耗尽厚度- 1.5mm能量分辨率<3.0 kev我们然后研究了一个脉冲形状鉴别器，优化了我们的井型phowich计数。在面包板上制作了原型电路并成功测试，该设计已应用于大规模集成电路的ASIC设计中。在项目的最后一年，我们制作了一个原型芯片。我们现在处于第二轮设计阶段。
