研究了Al_2O_3：C光学受激发光探测器在250 MeV铅笔质子束中的响应。OSLD响应被绘制成宽范围的平均剂量率高达9000GyS(-1)，相当于相当于每个脉冲中150kGyS(-1)的瞬时剂量率。提出了两种用于超高剂量率(闪光)实验的装置，使OSLD或生物样品能够在充满水的小瓶或圆柱体中进行辐照。OSLD被发现在所有剂量率下与剂量率无关，平均偏差
The response of Al2O3:C optically stimulated luminescence detectors (OSLDs) was investigated in a 250 MeV pencil proton beam. The OSLD response was mapped for a wide range of average dose rates up to 9000 Gy s(-1), corresponding to a similar to 150 kGy s(-1) instantaneous dose rate in each pulse. Two setups for ultra-high dose rate (FLASH) experiments are presented, which enable OSLDs or biological samples to be irradiated in either water-filled vials or cylinders. The OSLDs were found to be dose rate independent for all dose rates, with an average deviation
