Persistency

To perform persistency tests the detector is initially saturated. It is exposed to laboratory radiation for 1 minute with no filter placed and then is covered with a cool blank before proceeding to acquire data.

The conclusion is that it is necessary to repeat the reset cycle to remove the effect produced by initial saturation. Also, a dark current increase is associated to the previous saturation of the detector (see Fig. 7).
