Cryogenic Nano Positioner

STATEMENT OF REQUIREMENTS Title: Encoded Cryogenic Nano-positioners and Controllers Requesting Lab / Division / Group: Physical Measurements Lab / Applied Physics Division / Spin Electronics Group Requisition Number: NB686000-26-01956 I. BACKGROUND INFORMATION The Spin Electronics Group of the Physical Measurement Laboratory requires the purchase of position encoded cryogenic nano-positioners and the necessary controllers for characterization of superconducting devices and circuits. The encoded nano-positioners must be compatible with temperature below 4 Kelvin and vacuum pressures below 1x10 -8 Torr. The nano-positioners and controllers must be 1-to-1 compatible with the stages and controllers that are specified below. II. Purpose The position encoded cryogenic nano-positioners and controllers will be used to characterize devices and circuits made for our pi-ground state Josephson junction research and for testing electrical performance of superconducting digital logic circuits that will be imaged in our scanning superconducting quantum interference device microscope. The positioners and controllers must meet temperature specifications, dimensions and load specifications, and be comprised of all non- magnetic materials to ensure our ability to rapidly test new device and circuit designs and materials.
