  • Compact in-place gate valve for molecular beam experiments
    At the top right is the CF 16 flange (11) for the sliding linear motion feedthrough , whose operating range for moving the sledge is depicted by the double-headed arrow. vide optical and mechanical access to the source cham- ber.
  • A liquid helium target system for a measurement of parity violation in neutron spin rotation
    The epoxy resin provided additional mechanical stiffness to the laminate tube and suppressed helium dif- fusion and... ...heat transfer by thermal radiation from the aluminum vacuum jacket that surrounded the motion-control feedthrough tube. An aluminum CF flange was glued into the cold end of the tube, and a 316 stainless steel bellows assembly was glued into the room temperature end, which was located outside of target region (Figure 9).
    The A1 block with the atom chip was secured by four stainless rods welded on a vacuum CF flange with a 25-pin type-D electrical f e e d t h r ~ u ~ h . ~Then, the atom chip was electrically connected with a kapton coated UHV ribbon cable to the feedthrough . ...connecting external wires to the atom chip, several methods such as spot-welding, mechanical clamping, and soldering...
  • Resonant Elastic Soft X-Ray Scattering
    The basis of the diffractometer is a large differentially pumped two- circle rotary feedthrough driven outside the... Working in horizontal scattering geometry, the instrument combines very high mechanical precision with the capability of carrying... The latter consists of a large disc that comprises several UHV flanges up to a bore size... Detectors of various degrees of complexity can be assembled on DN 100 CF flanges and can then...
  • High intensity metal ion beam production with ECR ion sources
    Mechanical drawing of the low temperature axial oven. SS feedthrough CF Flange .
  • Hydrogen Storage In Magnesium Based Thin Film
    This viewport is actually an 8" CF flange with an extended welding pipe at one side and a window on the other side. ...the vacuum side, which has 70º of free motion along the vertical axis via a rotational feedthrough . For this purpose, a turbomolecular pump was backed by a mechanical pump.
  • A compact UHV package for microfabricated ion-trap arrays with direct electronic air-side access
    The completed package (Fig. 2b) yields a miniature multi-pin electronic feedthrough for UHV, and access to... Vacuum conductivity also prescribes the layout of the ‘‘UHV flat’’ (Fig. 2c), a custom-made stainless-steel cuboid on a DN40 ConFlat ( CF ) flange to which the electronic package is attached. The requirements for optical access and for mechanical rigidity further affect the geometry.
    Switching the atomic beam on or off is done by mechanical shuttering. A custom 4.5" CF reducer flange has two diametrally opposed 1.33" ports. ...the cold plate the 0.375" copper rod of a commercial high-current feedthrough is attached via...
  • The variable input coupler for the Fermilab Vertical Cavity Test Facility
    B. Mechanical Design and Installation ...main components, i.e., the antenna housing and the linear drive, and two flange holders that prevent... The bellows, welded between a mini CF flange and a diamond seal flange, is assembled together with... The RF antenna and META CERAM RF feedthrough previously connected together are mounted in the mini CF...
  • A crystal cleavage mechanism for UHV STM
    In Ref. [12] the cleaver is fixed on a flange ( CF 35 UHV) that can be placed anywhere along the path of rotation-translation feedthrough for the sample transfer. Mechanical system for sample cleavage.
