<p>An improved detector dewar assembly in which the flange supporting the upper cap of the dewar assembly comprises a radial ceramic matrix (16), including buried electrical leads (65, 66, 67). This ceramic matrix serves several purposes. First, it provides a vacuum tight electric feedthrough which connects jumper wires from the delineated coldwell axial matrix (80) to a pin assembly (62) imbedded in the exterior portion of the matrix feedthrough. Second, it includes metalizations (90, 92) on either the outer diameter or the top surtace and on its lower surface in order to provide a surface for connecting (by brazing or soldering) the lower base (22) and upper cap (17, 18, 20) assemblies. This improved dewar assembly is comprised primarily of metal subassemblies which are easily assembled, disassembled and tested.</p> |
