最近在质子位移损坏的 CCD 的暗电流中发现了时间涨落。这些波动采用随机电报信号的形式，具有明确的幅度和时间常数（对于高暗电流状态和低暗电流状态）。已经研究了温度和退火行为以及对质子注量的依赖性。提出了双稳态缺陷机制。
Temporal fluctuations have recently been discovered in the dark current of proton-displacement-damaged CCDs. These fluctuations take the form of random telegraph signals with well defined amplitudes and time constants (for the high and low dark current states). Temperature and annealing behaviour have been studied, as has the dependence on proton fluence. A bistable defect mechanism is proposed.
