摘要： A nano gas pump for generating gas flow, gas compression and gas rarefication is disclosed, which provides up to several orders of magnitude pressure difference, operates over a wide range of pressure from several millitorr to several atmospheres, and with pumping speeds from several nano liters to several liters per minute. The nano gas pump does not require any moving parts and generate gas flow using steep temperature gradients of more than 100 milli Kelvin over a mean free path of the local gas in the direction of the gas flow. Temperature gradients are created and restricted mostly to the gas doing the work, through an arrangement of PNP, NPN, PP, NN thermoelectric segments together with conductive interconnects. Contact resistance which drastically reduces the efficiency of a nanoscale thermoelectric heat pump is mitigated by overlapping thermoelectric segments and electric connections. Several exemplary embodiments are described based on linear (straight) and non-linear (turn) gas flow paths. Various staging configurations are also described.

摘要： A housing that defines a high vacuum work environment includes a monolithic member that has one side having a baffle region and a wall region. The baffle region includes at least one angularly contoured evacuation opening that forms a zig-zag flow path from the high vacuum work environment. In the preferred embodiment, each evacuation opening has a chevron-shaped cross section having an outer channel portion that is defined by baffle fins that are parallel or substantially parallel to each other, but at an acute angle relative to the side of the monolithic member. The wall region includes convection cooling fins that are aligned with the baffle fins.

摘要： The invention provides a hydrogen pump for vacuum insulation jackets for a vessel or a pipe which holds or through which flows a hydrogen-containing medium at temperatures such that hydrogen permeates into the jacket, comprising a palladium or palladium alloy membrane exposed on one side to an oxidizing atmosphere and on its other side to the evacuated space within the jacket, wherein the membrane enables the flow of the hydrogen from the evacuated space through the membrane into the oxidizing atmosphere.

摘要： A counterflow helium mass spectrometer leak detector in which a helium sample passes in a reverse direction through a diffusion pump to a mass spectrometer for measurement. The diffusion pump includes a conventional foreline and a second foreline provided with an ejector stage. A test sample is coupled from a test port through a bypass valve to the conventional foreline in a high sensitivity mode and is coupled to the second foreline in a low sensitivity mode. In the low sensitivity mode, the bypass valve is closed. An apertured control plate in the diffusion pump controls the relative reverse rates of duffusion from each foreline to the diffusion pump inlet by controlling the rates of vapor flow an annular pumping stages and to the ejector stage. The ejector stage includes a nozzle for directing a stream of vapor into the second foreline so as to inhibit flow of helium into the diffusion pump and establish a lower reverse diffusion rate at the second foreline. The disclosed configuration permits measurement of a large range of leak rates.

摘要： A vacuum diffusion pump includes a body assembly fabricated from a single piece of deep drawn sheet metal whereby a cylindrical wall of the body assembly, a flange for connecting the diffusion pump to a vacuum chamber, and a floor for a pool of diffusion pump fluid are all formed from the single piece of sheet metal. A boiler for heating the fluid to a vapor includes a cylindrical heating surface centrally located in the pool and extending axially from the bottom surface of the pool. The heating surface is surrounded by a separator tube having openings close to the bottom of the pool so that liquid in the pool enters an annular space between the separator and heating surface close to the bottom of the pool and rises in the annular space while being heated to vaporization. A solid heat insulator is located in another annular space between a cup and the exterior of a segment of the body wall that confines the pool and the exterior of the floor. A cooling coil is wrapped with an uneven pitch around the exterior of a cool wall portion of the body assembly so that the coil is in contact with the hottest parts of the wall portion and cooler parts of the wall portion are not in contact with the coil. A flange clamping plate surrounds the flange to clamp it against the chamber being evacuated. A baffle plate, positioned between a first stage of the pump and the flange, is mechanically connected to the cool wall portion through a path having a high thermal conductivity so that the baffle is cool enough to condense vapor of the diffusion pump fluid that impinges on it.

摘要： In a vacuum system a baffle-valve acts first as a baffle to reduce the backstreaming of a diffusion pump fluid into the main vacuum chamber being evacuated and secondly it can be used as a valve to provide complete isolation between the diffusion pump and the vacuum chamber. This enables the chamber to be open for service work while the diffusion pump is kept operating for rapid pump down. The foregoing dual use of the baffle/valve increases pumping efficiency because of higher conductance.
