Mount for cryogenic fast switching mechanism

摘要

A mount for a mountable element includes a frame, and a plurality of flexures supported by the frame. The plurality of flexures are configured to be outwardly extended against a restorative bias, so that the element can be inserted therebetween. The mount further includes a plurality of intermediate bonds that may be inserted between the plurality of flexures and the element while the plurality of flexures are outwardly extended. Among other things, a system and method mounting the element are also disclosed.

1. A mount for a mountable element comprising:
an annular frame defining a central aperture; a plurality of grooved flexures mechanically coupled to said frame, each grooved flexure comprising a cantilevered L-shaped arm comprising a first arm member extending axially from the frame at an attached end, a second arm member integrally part of a distal end of the first arm member extending in a circumferential direction, and a groove disposed on an unattached end of the cantilevered L-shaped arm, the plurality of grooved flexures defining a channel around a periphery of said central aperture, and configured to be radially outwardly extendable against a restorative bias for receiving an edge portion of the mountable element in the channel; wherein for each grooved flexure, the groove, second arm member and distal end are in the same plane as the plane defined by the grooves and the periphery of the mountable element, and wherein the unattached end of one grooved flexure is circumferentially adjacent and circumferentially spaced-apart from the distal end of a circumferentially adjacent flexure; and a plurality of intermediate bonds, arranged between the plurality of grooved flexures and the mountable element, said intermediate bonds being configured to cushion the mountable element against an acceleration of the mount, and to compensate for a mismatch between different coefficients of thermal expansion of the flexures and the mountable element so as to reduce a distortion of the mountable element.
