Abstract

A directly-converting X-ray detector includes: a directly-converting sensor material, which is to be maintained at a working temperature, and configured to have a DC voltage applied thereto; a conditioning unit configured to cause a base current to flow through the sensor material; a heating unit for the sensor material, the heating unit configured to be regulated by a regulating unit to maintain the working temperature; and a control device having a plurality of electronics units, which include the regulating unit. When a new configuration and/or a reconfiguration process takes place, the control device is configured to maintain the operation of the conditioning unit, and to interrupt the operation of the heating unit and/or maintain the operation of the heating unit with the control value most recently ascertained in ordinary operation of the regulating unit.
