Abstract: Systems and methods for improving the performance of dilution refrigeration systems are described. Electrostatic cryogenic cold traps employed in the helium circuit of a dilution refrigerator improve the removal efficiency of contaminants from the helium circuit. An ionization source ionizes at least a portion of a refrigerant that includes helium and number of contaminants. The ionized refrigerant passes through an electrostatic cryogenic cold trap that includes a number of surfaces at one or more temperatures along at least a portion of the fluid passage between the cold trap inlet and the cold trap outlet. A high voltage source coupled to the surfaces to causes a first plurality of surfaces to function as electrodes at a first potential and a second plurality of surfaces to function as electrodes at a second potential. As ionized contaminants release their charge on the electrodes, the contaminants bond to the electrodes.

Abstract: Adaptations and improvements to tubular metal powder filters include employing non-circular cross sectional geometries, aligning the inner conductor off-axis, replacing the inner conductive wire with a conductive trace carried on a printed circuit board, combining multiple filters within a single common outer conductive housing, and employing meandering and other non-parallel signal paths. The various adaptations and improvements are designed to accommodate single-ended and differential signaling, as well as superconducting and non-superconducting applications.

Abstract: Adaptations and improvements to tubular metal powder filters include employing cross sectional geometries of any suitable shape, aligning the inner conductor off-axis, replacing the inner conductive wire with a conductive trace or a superconductive trace carried by a printed circuit board, combining multiple filters within a single common outer conductive housing, and employing meandering and other non-parallel signal paths. The various adaptations and improvements are designed to accommodate single-ended and differential signaling, as well as superconducting and non-superconducting applications.
