用于星载X射线探测器校准的α标记X射线源
An alpha tagged X-ray source for the calibration of space borne X-ray detectors
摘要：
X射线探测器的校准对于了解探测器的性能特征及其随时间和不断变化的操作条件的变化非常重要。这使得能够最准确地将测量值转换为入射X射线光子能量的绝对值和相对值，从而可以测试源发射的物理模型。一般做法是将已知的X射线源（放射源）放入探测器外壳中进行校准。这就增加了背景。用来自同时发射的电荷粒子（如α粒子）的信号标记校准源可以识别用于校准的X射线事件。在本文中，我们提出了一种新的α标记X射线源的设计，使用Am ^241放射性源，并描述了其性能特点。还讨论了它在即将发射的Astrosat卫星上的应用。
英文摘要：
Calibration of X-ray detectors is very important to understand the performance characteristics of the detectors and their variation with time and changing operational conditions. This enables the most accurate translation of the measurements to absolute and relative values of the incident X-ray photon energy so that physical models of the source emission can be tested. It is a general practice to put a known X-ray source (radio active source) in the detector housing for the calibration purpose. This, however, increases the background. Tagging the calibration source with the signal from a simultaneously emitted charge particle (like alpha particle) can identify the X-ray event used for calibration. Here in this paper, we present a new design for an alpha-tagged X-ray source using Am^241 radio active source and describe its performance characteristics. Its application for the upcoming Astrosat satellite is also discussed.
