Gain Stabilization Circuit For Photomultiplier Tubes

View page
US Patent:
4918314, Apr 17, 1990
Filed:
Jan 6, 1989
Appl. No.:
7/293916
Inventors:
Darrell S. Sonne - Katy TX
Assignee:
Halliburton Logging Services, Inc. - Houston TX
International Classification:
G01T 128
US Classification:
250369
Abstract:
A photomultiplier tube stabilization circuit is set forth. It is particularly useful in downhole logging tools exposed to increases in temperature and to overcome component aging and drift. A high voltage power supply is connected for operation of a photomultiplier tube. The output of the PMT is amplified and applied to a set of comparators forming logic levels associated with threshold values affiliated with the spectral peak anticipated for the output data. The high voltage power supply is controlled upwardly or downwardly to vary operation of the PMT by means of a relatively simple control loop utilizing the comparators and means forming a control voltage for the high voltage power supply.

Gamma Ray Measurement Of Earth Formation Properties Using A Position Sensitive Scintillation Detector

US Patent:
4638158, Jan 20, 1987
Filed:
Jan 18, 1984
Appl. No.:
6/571897
Inventors:
Darrell S. Sonne - Katy TX
William J. Beard - Houston TX
Assignee:
Halliburton Company - Duncan OK
International Classification:
G01V 500
G01T 120
US Classification:
250266
Abstract:
A well logging system for measuring the radial density distribution of earth formations in the vicinity of a well borehole is provided. The system utilizes a single position sensitive gamma ray detector capable of deriving formation bulk density using the gamma-gamma scattering technique a different radial distances from the well borehole.

High Resolution Scintillation Crystal

US Patent:
4638164, Jan 20, 1987
Filed:
Oct 17, 1984
Appl. No.:
6/661636
Inventors:
Darrell S. Sonne - Katy TX
Allen Nunley - Houston TX
Assignee:
Halliburton Company - Duncan OK
International Classification:
G01V 506
G01T 1208
G01T 1202
US Classification:
250366
Abstract:
For use in downhole logging tools responsive to gamma rays or x-rays, an improved scintillation device is set forth. In the preferred and illustrated embodiment, a scintillation crystal, typically sodium iodide (thallium activated), is utilized. It is an elongated, regular structure having two ends, and separate photomultiplier tubes (PMT) are attached at the separate ends. The two PMT output signals are supplied to a circuit which forms a signal adjusted or modified to compensate for loss of light energy arising during transmission through the scintillation crystal to the PMT's.
