US Patent:

20080156996, Jul 3, 2008

Filed:

Feb 23, 2007

Appl. No.:

11/678225

Inventors:

Joseph A. Nicolosi - Bardonia NY, US
Sun K. Park - Paramus NJ, US
Leong Ying - Hoboken NJ, US
Steven Cacioppo - Mahwah NJ, US
Michael Solazzi - Hillsdale NJ, US
Bob Westerdale - Hewitt NJ, US

Assignee:

AMETEK, INC. - Paoli PA

International Classification:

G01T 1/24
F25B 9/02

US Classification:

25037015

Abstract:

An apparatus for the indirect cooling of a silicon drift detector (SDD) includes an enclosure with a vacuum maintained therein, at least one SDD module that generates substantially no heat positioned within the enclosure, a cooling engine positioned remote from the SDD module within the enclosure for cooling the SDD module, whereby heat is generated by the cooling engine, a thermal conduction device comprising a first end thermally coupled to the cooling engine and a second end thermally coupled to the SDD module and a heat removal device thermally coupled to the cooling engine. The cooling engine indirectly cools the SDD module by transferring thermal energy through the thermal conduction device from the SDD module and the heat removal device dissipates the heat generated by the cooling engine to the environment surrounding the enclosure. A method for indirectly cooling a radiation detector is also provided.

International Classification:

H01J 37244

US Classification:

25037006

Abstract:

A pass-through shutter mechanism enables the semiconductor crystal of an energy dispersive x-ray detector to extend beyond the shutter mechanism for analysis, adjacent to the sample, achieving optimum solid angle collection efficiency. The shutter mechanism provides optimum protection of the semiconductor detector crystal from high energy x-ray or secondary electron events produced in the chambers of electron microscopes, microprobes, x-ray spectrometers, etc.

Appl. No.:

7/898772

Inventors:

Joseph A. Nicolosi - Bardonia NY
Costas Blionas - Hackensack NJ

Assignee:

North American Philips Corporation - New York NY

International Classification:

G01T 100
G01T 124

US Classification:

2503361

Abstract:

An x-ray detector assembly is improved by covering the detector holder with a dielectric film to prevent contamination of the sides of the detector without covering the front of the detector. The film does not hermetically seal the detector holder.
