A synchrotron beam has been used to investigate the radiation tolerance of a PILATUS II module. It has been demonstrated that radiation-induced threshold shifts become significant above 30 Mrad. Individual adjustment of pixel thresholds after irradiation enabled retention of standard behaviour in excess of 40 Mrad. This implies that a module can be continuously irradiated for in excess of 40 days at an individual pixel count rate of 10(6) counts s(-1).
利用同步加速器光束研究了PILATUS II模块的辐射耐受性。结果表明,当辐射剂量超过30兆拉德时,辐射引起的阈值偏移变得显著。辐照后对像素阈值进行单独调整,可使模块在超过40兆拉德的剂量下保持标准性能。这意味着该模块可以在单个像素计数率为10(6)个计数每秒(-1)的情况下连续辐照超过40天。
