摘要： Provided herein are articles of manufacture, systems, and methods employing a gas-deflector plate in low to ultra-high vacuum systems that use differential pumping (e.g., gas-target particle accelerators, mass spectrometers, and windowless delivery ports). In certain embodiments, the gas-deflector plate is configured to be positioned between higher and lower pressure regions in a pressurized system, wherein the gas-deflector plate has a channel therethrough shaped and/or angled such that jetting gas moving through the channel enters the lower pressure region at an angle offset from the vertical axis of the gas-deflector plate and/or the channel. In other embodiments, a jet-deflector component is employed such that the jetting gas strikes such jet-deflector component and is re-directed in another direction.

摘要： A system and method for performing active scanning on a nuclear fuel rod are provided. The system includes an electrically-driven neutron generator including an ion source, an accelerator, and a target; a moderator surrounding the neutron generator and configured to moderate neutrons generated by the neutron generator; a fuel rod channel disposed within the moderator, the fuel rod channel configured to receive a nuclear fuel rod and subject the nuclear fuel rod to a predetermined neutron flux; and a plurality of radiation detectors. When the nuclear fuel rod is subjected to the predetermined neutron flux, neutrons induce a secondary radiation of prompt and delayed gamma emissions, neutron emission, or a combination thereof that are detected by the plurality of radiation detectors to determine an amount of fissile material in the nuclear fuel rod and a spatial distribution of the fissile material along a length of the nuclear fuel rod.
