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 tile high and low dark current states). Temperature and annealing behavior have been studied, as has the dependence on proton fluence. A bistable defect mechanism is proposed.
