An assembly () for monitoring ionising radiation comprises a detector substrate () for generating electronic charge responsive to incident ionising radiation, the detector substrate () having an array of ionising radiation sense volumes () formed in it. A circuit substrate () supporting an array of read-out circuits () corresponding to the array of sense volumes is mechanically and electrically coupled to the detector substrate (). Each of the read-out circuits () is switchable between first and second charge integration modes for receiving charge from a corresponding sense volume. A charge integration circuit () is configured in the first charge integration mode to integrate charge corresponding to sensing of a single ionising radiation detection event in a corresponding sense volume and in the second charge integrating mode to integrate charge corresponding to sensing a plurality of ionising radiation detection events in the corresponding sense volume.

Ionising radiation detector

Embodiments of the invention are concerned with a method of manufacturing a radiation detector having one or more conductive contacts on a semiconductor substrate, and comprise the steps of: applying a first conductive layer to a first surface of the semiconductor substrate; applying a second conductive layer to form a plurality of contiguous layers of conductive materials, said plurality of contiguous layers including said first conductive layer; and selectively removing parts of said plurality of contiguous layers so as to form said conductive contacts, the conductive contacts defining one or more radiation detector cells in the semiconductor substrate.
