CP525 Dip Probe


The CP525 Cryoprobe is the interface between a Josephson array voltage chip and its microwave and bias electronics systems.

The CP525 Cryoprobe can mount to a variety of liquid Helium dewars, and contains its own level sensors and readouts. Probe length and mounting flange specifications are built to meet customer requirements.

The CP525 Cryoprobe is now used in Metrology Standards Laboratories all over the world, including SIRIM, IEM, Lockheed Martin, NPL India, NIST, and others.

Features

  • The CP 525 Cryoprobe uses a low loss, internally silver plated stainless steel waveguide with WR-12 input and output flanges. The typical attenuation at 75 GHz is 0.8 dB with periodic resonant peaks of 1.5 dB.
  • Heat leak less than 0.6 liter of liquid helium/day.
  • Milled aluminum connector/filter box for LC filter network, fully wired with Bendix PT06A-16-8P connector for precision voltage output.
  • Helium vent system with relief and shutoff valves. Helium gas is vented through the probe tube and filter box. Allows easy connection for Helium recycling; aids cooling of the probe and lowers Helium consumption.
  • Helium level sensor and display.
  • G-10 support tube.
  • Sliding flange assembly (specify Dewar flange).
  • Magnetic shield: AD-MU-80 standard (CP-EXP-1184 optional).
  • Low loss silver-plated stainless steel waveguide with WR-12 microwave horns.
  • Electrical leakage resistance between precision voltage leads is 100 Gohm or higher at 10V.
  • Comes boxed for international shipping.
