6.4.4 Cleaning the CCD
Since kinetics is most often used in asynchronous, single-shot experiments, it is
important that CCD be cleared of accumulating background or dark charge while it is
waiting for an external trigger. To take care of this, ProEM automatically cleans the CCD
one row at a time before the arrival of the first trigger. This keeps the charge buildup on
the CCD to a minimum at the same time minimizing the timing jitter (determined by
vertical shift time of a single row). If desired, the number of cleans can be set to zero for
the best jitter performance. However, the camera must be in a dark environment to
minimize the background.
