Abstract
A drift detector produces an indication of an occurred hit of a quantum in the detector element. For neutralising accumulated charge in the detector element, indications of occurred hits are used to trigger pulses of deliberately increased neutralisation current into the drift detector for the duration of a limited time interval. Alternatively such triggering may be based on the operation of a timer.
