US Patent:

20060033432, Feb 16, 2006

Filed:

Aug 10, 2004

Appl. No.:

10/915622

Inventors:

Charles Tomasetti - Leola PA, US
Scott Moulzolf - Lancaster PA, US

International Classification:

H01J 43/00
H01J 43/04

US Classification:

313532000, 313536000

Abstract:

Photomultiplier tubes with improved collection of incident radiation, especially from the periphery of the front face of the tube, and that more efficiently couple the collected radiation to the photocathode, and moreover have higher packing densities when assembled into arrays, resulting in enhanced imaging characteristics. The improvements in radiation collection and photomultiplier tube packing density are gained by a combination of several features including: tapering the edges of the faceplate so that the faceplate subtends an area as large or larger than any other cross-sectional area of the photomultiplier tube; forming the junction between the faceplate and metal tube on the underside of the faceplate, and in such a manner as to avoid obscuring the optical path between the incident radiation and photocathode; and utilizing the tapered edge of the faceplate as a reflector to couple radiation incident on the periphery of the faceplate to the photocathode.

Abstract:

Methods and systems for attaching a device to a substrate for operation of the device under variable conditions includes attaching a device to a substrate, disposing a removable material over a first portion of the device, positioning a second portion of the device adjacent to the substrate, operably attaching a retainer to the substrate adjacent to the device with a part of the retainer disposed over the removable material, and removing the removable material to form a gap between the device and the retainer so that the device is retained on the substrate, and wherein the gap allows the device to move freely relative to the retainer and the substrate in response to changes in temperature.
