Cryogenic, high-resolution x-ray detector with high count rate capability

Title: Cryogenic, high-resolution x-ray detector with high count rate capability

Abstract

A cryogenic, high-resolution X-ray detector with high count rate capability has been invented. The new X-ray detector is based on superconducting tunnel junctions (STJs), and operates without thermal stabilization at or below 500 mK. The X-ray detector exhibits good resolution (.about.5-20 eV FWHM) for soft X-rays in the keV region, and is capable of counting at count rates of more than 20,000 counts per second (cps). Simple, FET-based charge amplifiers, current amplifiers, or conventional spectroscopy shaping amplifiers can provide the electronic readout of this X-ray detector.

High resolution, multiple-energy linear sweep detector for x-ray imaging

Patent Perez-Mendez, Victor [Berkeley, CA]; Goodman, Claude A [Kensington, CA]

Apparatus for generating plural electrical signals in a single scan in response to incident X-rays received from an object. Each electrical signal represents an image of the object at a different range of energies of the incident X-rays. The apparatus comprises a first X-ray detector, a second X-ray detector stacked upstream of the first X-ray detector, and an X-ray absorber stacked upstream of the first X-ray detector. The X-ray absorber provides an energy-dependent absorption of the incident X-rays before they are incident at the first X-ray detector, but provides no absorption of the incident X-rays before they are incident atmore »« less

High resolution collimator system for X-ray detector

Patent Eberhard, Jeffrey W [Schenectady, NY]; Cain, Dallas E [Scotia, NY]

High resolution in an X-ray computerized tomography (CT) inspection system is achieved by using a collimator/detector combination to limit the beam width of the X-ray beam incident on a detector element to the desired resolution width. In a detector such as a high pressure Xenon detector array, a narrow tapered collimator is provided above a wide detector element. The collimator slits have any desired width, as small as a few mils at the top, the slit width is easily controlled, and they are fabricated on standard machines. The slit length determines the slice thickness of the CT image.

High count rate thermal neutron detectors and electronics

Patent Ianakiev, Kiril; Iliev, Metodi; Swinhoe, Martyn; ...

Improved, high count rate thermal neutron counters and electronics enabling new, higher measurement capabilities are disclosed. Next generation 3He and 10B tubes may include an electronics package capable of operating at higher count rates and in higher gamma fields and providing more efficient use of 3He gas. Conventional detector systems may also be upgraded, providing a possible solution to measure spent nuclear fuel with high neutron efficiency previously not possible in 235U fission counter systems. Switching the number of tubes per amplifier allows use of the measured nuclear material for a calibration standard for dead time correction, increasing accuracy ofmore »« less

High collection efficiency X-ray spectrometer system with integrated electron beam stop, electron detector and X-ray detector for use on electron-optical beam lines and microscopes

Patent Zaluzec, Nestor J.

An X-ray spectrometer systems and methods are provided for implementing signal detection for use on electron-optical beam lines and microscopes. The X-ray Spectrometer System (XSS) includes an X-ray detector (XD) measuring the X-ray signal and positioned proximate to a specimen. An environmental isolation window together with an electron beam stop is disposed between XD and the specimen. The environmental isolation window and the electron beam stop protect XD from electrons directly transmitted through the specimen. An electron detector is located between the electron beam stop and the specimen allowing the measurement of scattered electrons. The XD measures an X-ray signalmore » in the X-ray spectrometer system.« less
