This paper presents the calibration of two different kinds of image plates (IPs) for detecting electrons with kinetic energy in the range of 150 keV-1.75 MeV. The calibration was performed using a Sr β source. The paper also provides the measured fading response for the IPs in the time range from 12 min to 18 h. Calibration results are compared to Monte Carlo simulations of energy deposited by the electrons in the sensitive layer of the IPs. It was found that within this energy range a linear relation between simulated energy deposited by the electron in the phosphor layer and the measured photo stimulated luminescence in the IP is adequate to model the response of the IP.
本文介绍了两种不同类型的影像板（IP）的校准，用于检测动能在150 keV至1.75 MeV范围内的电子。该校准使用锶β源进行。本文还给出了影像板在12分钟至18小时时间范围内测得的褪色响应。将校准结果与电子在影像板敏感层中沉积能量的蒙特卡罗模拟结果进行了比较。结果发现，在该能量范围内，电子在磷光体层中模拟沉积的能量与影像板中测得的光激励发光之间的线性关系足以对影像板的响应进行建模。
