Improving thermal contact

PreviousCooling down with LHeNextT-dependent measurements

Last updated 2 years ago

The screws on the manipulator head (left photo) can be tightened to provide a better thermal contact while cooling for the samples that require lowest possible temperatures. Vacuum screwdriver is located in the Preparation Chamber, close to the heater (right photo).

To tighten the screws:

  • Move manipulator to preparation chamber;

  • Close the valve between the chambers;

  • Go to a saved position "screwdriver" or rotate manually tilt and polar angles;

  • Do not apply force! Just screw until the end without making it too tight;

  • Return to "Transfer_PREP" position.

To take your sample out later you will need to loosen the screws by ca. 2 full turns.
