ABSTRACT:
In a capsule for a detector operating in an ultra high vacuum suitable as a gamma radiation spectrometer, there is provided a detector chamber in which the detector is mounted and a getter chamber in which a getter element is mounted and the getter chamber is separated from the detector chamber by a thermal protection structure to prevent heating of the detector when the getter element is heated for conditioning. The getter element serves to maintain an ultra high vacuum in the detector chamber over a long period of operation.
