CCD97是e2v技术系列电子倍增ccd(EMCCDs)中的一款微光(L3)器件。该设备使用e2v专利的扩展增益寄存器，并通过使用适当设计的电极来最大化信号，同时将噪声的影响保持在最低限度。这种设备的性质使其非常适合与闪烁体一起使用，以便看到来自单个X射线光子的单独闪光。通过对单个X射线事件的检查，可以分析闪烁体中的每个相互作用，以确定相互作用的亚像素位置。利用Geant4工具包的建模能力，可以模拟X射线事件，从而检查与已知能量和相互作用点的相互作用。通过将实验结果和模拟结果相结合，讨论了这种器件的光谱性能。
The CCD97 is a low light level (L3) device from e2v technologies range of electron multiplying CCDs (EMCCDs). The device uses e2v's patented extended gain register and through the use of appropriately designed electrodes can be used to maximise the signal whilst keeping the impact of the noise to a minimum. The nature of this device makes it ideal for use with a scintillator in order to see individual flashes of light from single X-ray photons. Through the examination of individual X-ray events, it is possible to analyse each interaction in the scintillator to determine the sub-pixel position of the interaction. Using the modelling capabilities of the Geant4 toolkit it is possible to simulate X-ray events and thus examine interactions with known energy and point of interaction. Through bringing together the experimental and simulated results, the spectral capabilities of such a device are discussed.
