    • 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 surface 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.
    • 一种改进的检测器杜瓦瓶组件,其中支撑杜瓦瓶组件的上盖的法兰包括径向陶瓷基体(16),该径向陶瓷基体包括埋入式电引线(65,66,67)。 这种陶瓷基体有多种用途。 首先,它提供了一个真空密封的电馈通,它将跨接线从描绘的冷井轴向矩阵(80)连接到嵌入在矩阵馈通的外部部分中的销组件(62)。 其次,它包括在外径或顶面以及其下表面上的金属化(90,92),以提供用于连接(通过钎焊或钎焊)下基座(22)和上盖(17, 18,20)组件。 这种改进的杜瓦瓶组件主要由易于组装,拆卸和测试的金属组件组成。

    • An improved detector dewar assembly in which the flange supporting the upper cap (18, 20) of the dewar assembly comprises a disc ceramic matrix (40), including buried electrical leads (66, 67). This disc serves several purposes. First, it provides a vacuum tight electric feedthrough which connects a tape cable (36) from the detector assembly (14) to a pin assembly (64) imbedded in the exterior portion of the disc feedthrough. Second, it includes metalizations (108, 90) on its top and lower surface in order to provide a surface for connecting (by brazing or soldering) the upper cap (18, 20) assembly and the major vessel wall ( 1 5). A tape cable (36) comprising wires (80) embedded in a flexible nonconductive matrix connects the detector element leadout wires with the electrical connectors of the feedthrough disc. The cable forms a collar which substantially surrounds the coldwell (10) and has tabs (84) at its basal portion which fold up to attach to pin or pad connectors (62) on the lower surface of the disc. The use of Manganin, Constantan, or Balco wires produces a tape cable which significantly reduces the heat load on the dewar refrigerator system. Solder/bond rings and pads (110, 112, 114, 116) positioned both on the endwell and disc assembly mate to solder bondl rings and pads/dots positioned on the tape cable thereby providing stress relief.
    • 一种改进的检测器杜瓦瓶组件,其中支撑杜瓦瓶组件的上盖(18,20)的凸缘包括盘式陶瓷基体(40),其包括埋入式电导线(66,67)。 这张光盘有几个用途。 首先,它提供了一个真空密封的电馈通,其将来自检测器组件(14)的带缆(36)连接到嵌入在盘馈通的外部部分中的销组件(64)。 其次,它包括在其上表面和下表面上的金属化(108,90),以便提供用于连接(通过钎焊或钎焊)上帽(18,20)组件和主要血管壁(15)的表面。 包括嵌入柔性非导电矩阵中的导线(80)的带状电缆(36)将检测器元件引出线与馈通盘的电连接器连接。 该电缆形成基本上围绕冷阱(10)并且在其基部具有凸片(84)的套环,该凸片折叠起来以附接到盘下表面上的销或垫连接器(62)。 使用Manganin,Constantan或Balco电线可生产带状电缆,可显着降低杜瓦制冷机系统的热负荷。 定位在端孔和盘组件上的焊料/粘合环和垫(110,112,114,116)与位于带缆上的焊接环和垫/点焊接,从而提供应力消除。
