46671072, May 19, 1987

Filed:

Jun 19, 1985

Appl. No.:

6/746496

Inventors:

Ching L. Wang - Livermore CA

Assignee:

The United States of America as represented by the United States
Department of Energy - Washington DC

International Classification:

G01T 300

US Classification:

250390

Abstract:

The invention comprises a neutron detector (50) of very high temporal resolution that is particularly well suited for measuring the fusion reaction neutrons produced by laser-driven inertial confinement fusion targets. The detector comprises a biased two-conductor traveling-wave transmission line (54, 56, 58, 68) having a uranium cathode (60) and a phosphor anode (62) as respective parts of the two conductors. A charge line and Auston switch assembly (70, 72, 74) launch an electric field pulse along the transmission line. Neutrons striking the uranium cathode at a location where the field pulse is passing, are enabled to strike the phosphor anode and produce light that is recorded on photographic film (64). The transmission line may be variously configured to achieve specific experimental goals.

Appl. No.:

Inventors:

Assignee:

Department of Energy - Washington DC

International Classification:

G01N 2322

US Classification:

378156

Abstract:

An apparatus utilizing filter-fluorescer combinations is provided to measure short bursts of high fluence x-rays above 120 keV energy, where there are no practical absorption edges available for conventional filter-fluorescer techniques. The absorption edge of the prefilter is chosen to be less than that of the fluorescer, i. e. , E. sub. PRF E. sub. F. In this way, the response function is virtually zero between E. sub. PRF and E. sub. F and well defined and enhanced in an energy band of less than 1000 keV above the 120 keV energy.

Assignee:

International Classification:

H01J 3150

US Classification:

250213VT

Abstract:

An improved streak camera in which a microchannel plate electron multiplier is used in place of or in combination with the photocathode used in prior streak cameras. The improved streak camera is far more sensitive to photons (UV to gamma-rays) than the conventional x-ray streak camera which uses a photocathode. The improved streak camera offers gamma-ray detection with high temporal resolution. It also offers low-energy x-ray detection without attenuation inside the cathode. Using the microchannel plate in the improved camera has resulted in a time resolution of about 150 ps, and has provided a sensitivity sufficient for 1000 KeV x-rays.

US Patent:

Filed:

May 14, 1981

Appl. No.:

6/263649

Inventors:

Ching L. Wang - Livermore CA

International Classification:

G01T 300

US Classification:

250390

Abstract:

Apparatus for improved sensitivity and time resolution of a neutron measurement. The detector is provided with an electrode assembly having a neutron sensitive cathode which emits relatively low energy secondary electrons. The neutron sensitive cathode has a large surface area which provides increased sensitivity by intercepting a greater number of neutrons. The cathode is also curved to compensate for differences in transit time of the neutrons emanating from the point source. The slower speeds of the secondary electrons emitted from a certain portion of the cathode are matched to the transit times of the neutrons impinging thereupon.
