摘要： A cold trap includes a fluid conduit having a fluid flow path therethrough, a length along the fluid flow path and a width transverse to the fluid flow path. The width of the fluid conduit is greater than the length. A cryopumping array having an outer rim surrounding a central opening is positioned within the fluid conduit transverse to the fluid flow path such that the fluid flow path extends through the central opening of the array. The outer rim captures water vapor from the fluid flow path. The array has a transverse width and a rim width which are both greater than the thickness of the array. A conductive strut extends from the array through the fluid conduit transverse to the fluid flow path for a conductively coupling the array to a cryogenic cooling source which cools the array to cryogenic temperatures.
