Abstract
A CCD Device of the type for providing charge gain by impact ionisation has a multiplication register. Gain provided by a subset of the elements of the multiplication register are independently controllable from other elements in the register. This enables the register to be used in one setting with the same gain applied to all elements and a different setting with a subset of elements arranged to provide a different gain. By comparing the two signals, the gain provided by each element and the register as a whole may be derived.
