摘要： Disclosed is a radiation logging tool, comprising a tool housing; a compact generator that produces radiation; a power supply coupled to the compact generator; and control circuitry. Embodiments of the compact generator comprise a generator vacuum tube comprising a source generating charged particles, and a target onto which the charged particles are directed; and a high voltage supply comprising a high voltage multiplier ladder located laterally adjacent to the generator vacuum tube. The high voltage supply applies a high voltage between the source and the target to accelerate the charged particles to a predetermined energy level. The compact generator also includes an electrical coupling between an output of the high voltage supply and the target of the generator vacuum tube to accommodate the collocated positions of the generator vacuum tube and the high voltage power supply.

摘要： A scintillator type radiation detector package is provided including a scintillation crystal directly coupled to the window of a photomultiplier. A scintillator package is also provided having a longer life at wellbore temperature with minimal deterioration of a hygroscopic scintillation crystal(s). Direct optical coupling of the scintillator to the photomultiplier reduces the amount of light lost at coupling interfaces and improved detection resolution over the conventional structures having separate packages for crystal and photomultiplier.

摘要： Systems, methods, and apparatuses to determine an operation gas pressure in a neutron radiation generator are described. In certain aspects, a method to determine the operation gas pressure includes receiving an operation radiation signal from a radiation generated by electrons backstreaming in a radiation generator, and determining from the operation radiation signal an operation gas pressure in a chamber of the radiation generator. An operation radiation signal may be received from a radiation detector associated with a neutron radiation generator. A radiation detector may detect radiation produced by particles (e.g., electrons) striking a portion (e.g., a cathode) of the neutron radiation generator.

摘要： An ion source for use in a radiation generator includes an active cathode configured to emit electrons on a trajectory away from the active cathode, at least some of the electrons as they travel interacting with an ionizable gas to produce ions. In addition, there is at least one extractor downstream of the active cathode having a potential such that the ions are attracted toward the at least one extractor.

摘要： Systems, methods, and apparatuses to identify functional issues of a neutron radiation generator are described. In certain aspects, a method includes receiving an operation extractor signal from an extractor electrode of a radiation generator, determining a calculated extractor signal of the radiation generator, and comparing the operation extractor signal to the calculated extractor signal. The calculated extractor signal may be determined from an operation acceleration signal from an acceleration member of the radiation generator, an operation electron beam signal from electrons backstreaming in the radiation generator, an ion signal of an ion beam of the radiation generator, or a combination thereof.

摘要： Logging-while-drilling tools incorporating an electronic radiation generator, such as an electronic X-ray generator, and a method for using the same are provided. One example of such a logging-while-drilling tool may include a circumferential drill collar, a chassis disposed radially interior to the drill collar, and an electronic X-ray generator and an X-ray detector disposed within the chassis. The electronic X-ray generator may emit X-rays out of the logging-while-drilling tool into a subterranean formation. The X-ray detector may detect X-rays that return to the logging-while-drilling tool after scattering in the subterranean formation, which may be used to determine a density and/or a lithology of the subterranean formation.
