A structure is prepared by preparing a getter assembly by furnishing a single-piece getter base including a getter substrate and a getter-shield precursor, affixing a getter material to the getter substrate, and processing the getter-shield precursor to form a getter shield. The processing is preferably performed by folding at least a portion of the getter-shield precursor to overlie the getter material affixed to the getter substrate. There may be provided a vacuum housing and a device. The getter assembly and the device are inserted into the vacuum housing, and the vacuum housing is evacuated and sealed.

Method for preparing a getter structure and getter structure

A radiation detector () has a base (), a frame (), a window (), and solder layers () formed from a solder pre-form () to define a vacuum chamber (). Feedthroughs () penetrate the base () for electrical connection to internal components. A method for sealing the detector () aligns a lower detector assembly (), the frame () the window (), and the solder pre-forms () in a non-sealed relation within a processing chamber (). High temperature and low pressure is imposed, and the getter () is activated by resistive heating imposed by current leads (). The window (), frame (), and lower detector assembly () are then pressed together and sealed by the liquefied solder pre-forms (). The method eliminates the need for a seal port, combines several steps within the processing chamber (), and eliminates certain prior art cleaning steps.
