Abstract:

A support structure for a membrane comprises a plurality of support members and at least one flange, including: (a) a first set of spoke-like support members that extend generally from at least one flange toward a common hub and that have a distal end joined to at least one flange and a proximal end joined to the common hub; and (b) at least one subsequent set of spoke-like support members that are distributed between circumferentially adjacent pairs of spoke-like support members from the prior sets and that extend generally from at least one flange toward the hub, each having a distal end joined to at least one flange and a proximal end connected to the nearest circumferentially adjacent pair of spoke-like support members from the prior sets via a pair of approximately straight anchoring support members which join together and form an angular joint at or near said proximal end, with the vertex of said angular joint pointing generally away from the hub.

Abstract:

An improved radiation window comprises a film permeable to radiation disposed on a support structure. The support structure comprises a primary transmissive area comprising a plurality of support members defining a plurality of apertures for radiation to pass through; a flange disposed around the periphery of the primary transmissive area having generally greater mechanical rigidity than the primary transmissive area; and a transition region disposed between, and contiguous with, the primary transmissive area and the flange; the transition region having generally greater mechanical rigidity than the primary transmissive area and generally lesser mechanical rigidity than the flange, thereby providing an intermediate rigidity transition between the dissimilar rigidities of the primary transmissive area and the flange. A radiation detection system comprises a sensor configured to detect radiation, disposed behind such an improved radiation window.
