Photon Detector Based Upon An Activated Lanthanide Beryllate Scintillator
US Patent:
5483062, Jan 9, 1996
Filed:
Jan 21, 1994
Appl. No.:
8/184147
Inventors:
John B. Czirr - Mapleton UT
Manuel Berrondo - Orem UT
Manuel Berrondo - Orem UT
Assignee:
Merrill Corporation - Salt Lake City UT
International Classification:
G01V 504
G01T 1202
G01T 1202
US Classification:
250256
Abstract:
A photon detector includes an activated lanthanide beryllate crystal, such as activated lanthanum beryllate, as a scintillator to detect photons. In one embodiment, the lanthanide beryllate crystal is doped with cerium.
Low-Energy Neutron Detector Based Upon Lithium Lanthanide Borate Scintillators
US Patent:
5734166, Mar 31, 1998
Filed:
Sep 20, 1996
Appl. No.:
8/706141
Inventors:
John B. Czirr - Mapleton UT
Assignee:
Mission Support Incorporated - Salt Lake City UT
International Classification:
G01T 306
US Classification:
25039011
Abstract:
An apparatus for detecting neutrons includes a cerium activated scintillation crystal containing. sup. 10 B, with the scintillation crystal emitting light in response to. alpha. particles emitted from the. sup. 10 B(n,. alpha. )Li* reaction. The apparatus also includes a gamma scintillator positioned adjacent the crystal and which generates light in response to gamma rays emitted from the decay of Li*. The apparatus further includes a first and a second light-to-electronic signal converter each positioned to respectively receive light from the crystal and the gamma scintillator, and each respectively outputting first and second electronic signals representative of. alpha. particles from the. sup. 10 B(n,. alpha. )Li* reaction and gamma rays from the. sup. 10 B(n,. alpha. )Li* reaction.
Method Of Downhole Neutron Monitoring
US Patent:
5008067, Apr 16, 1991
Filed:
Mar 7, 1990
Appl. No.:
7/492395
Inventors:
John B. Czirr - Mapleton UT
International Classification:
G01T 300
G01V 500
G21G 106
G01V 500
G21G 106
US Classification:
376159
Abstract:
A method of downhole neutron monitoring using an oxygen containing scintillating material to generate scintillator light as a function of electrons and gamma rays emitted from the product of the. sup. 16 O (n,p) reaction in a scintillator, converting the generated scintillator light to an electrical signal, and using the electrical signal to record the flux of measured neutrons.
Method For Determining Mine Roof Competency
US Patent:
4686849, Aug 18, 1987
Filed:
Dec 6, 1985
Appl. No.:
6/805772
Inventors:
John B. Czirr - Mapleton UT
International Classification:
G01N 1508
G01N 1908
G01N 1908
US Classification:
73 38
Abstract:
Mine roof competency is determined by injecting a pressurized gas into a borehole drilled in the roof of the mine and measuring the rate of pressure loss. A high rate of pressure loss is indicative of a dangerous mine roof. A tracer gas may also be injected into the borehole to determine the extent of cracks in the roof if a dangerous condition has been determined.
Neutron And Photon Monitor For Subsurface Surveying
US Patent:
5313504, May 17, 1994
Filed:
Oct 22, 1992
Appl. No.:
7/964966
Inventors:
John B. Czirr - Mapleton UT
International Classification:
G01T 300
G01V 500
G01V 500
US Classification:
376153
Abstract:
An apparatus to survey subsurface formations includes a sonde which is configured to move through a borehole. The sonde includes a neutron generator that emits neutrons into the subsurface formations. A crystal detector connected to the sonde monitors the neutron output of the neutron generator. The crystal detector can comprise an yttrium silicate crystal, an yttrium aluminate crystal, a lanthanum phosphate crystal, or a lutetium phosphate crystal. A lanthanum phosphate crystal or a lutetium phosphate crystal can also be used to detect photons coming from the subsurface formations. The sonde pressure casing can be fabricated from borated stainless steel to shield the internals of the sonde from thermal neutrons.
