Abstract
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.
