摘要： A detector signal processing circuit comprises a current/voltage converting unit (21) which converts the current value, which is converted by a neutron detector (3), to a voltage value which corresponds to the current value; a variable gain amplifying unit (22) which includes an operating amplifier, in which a D/A converter is added, and amplifies the voltage value which is converted by the current/voltage converting unit (21); a regulation control means (26 to 28) which regulates a gain of the D/A converter; and a comparator (29) which automatically compares an output voltage, which is amplified by the variable gain amplifying unit (22), in accordance with a reference value which is previously set, so as to output the output voltage to the regulation control means (26 to 28).

摘要： A method and apparatus for inspecting an object (420) is presented. Radiation is emitted from a radiation source (218, 302). A beam (234, 314) is formed from a portion of the radiation emitted by the radiation source (218, 302) using a collimator (220, 304). The collimator is connected to the radiation source by a bearing system (221, 306) comprising a first structure (236, 316) associated with the radiation source and a second structure (238, 318) connected to the first structure. The second structure is configured to hold the collimator (220, 304). The second structure of the bearing system is moved using a movement system (223, 308) such that the second structure rotates in one of a plurality of directions (328, 330) substantially about a center point (228, 402) in the radiation source while the radiation source (218, 302) remains stationary relative to the second structure. Rotation of the second structure substantially about the center point in the radiation source changes a direction in which the beam is directed.

摘要： A method for operating a pulsed neutron generator including an ionizer with an electron emitting cathode and a grid wherein the cathode and grid are disposed in a sealed chamber. At least one of the following is applicable to the ionizer; a distance between the cathode and the grid, a cathode current and/or a potential on the grid are selected such that the ionizer operates at most about one-half the space charge limited current for a grid current selected to provide a predetermined amount of neutron production.

摘要： In one example, a radiation source comprises a housing and an acceleration chamber within the housing, with a peak acceleration energy greater than the lowest neutron production threshold of tantalum. A source of charged particles is supported by the housing to emit charged particles into the acceleration chamber. A target is supported by the housing downstream of the acceleration chamber. The target consists essentially of at least one isotope having a neutron production threshold greater than the peak acceleration energy. No neutrons are therefore generated. The source may also comprise a collimator, target shielding, and/or housing shielding comprising at least one isotope having a neutron production threshold greater than the peak acceleration energy, reducing or eliminating neutron generation as compared to the prior art, as well. Systems comprising the source, methods of operation of the source, and methods of manufacture of the source are also disclosed.
