Sample Rotation Probe

We offer a sample probe which allows the sample to be manually rotated through
330 degrees around the vertical axis. The sample probe comprises a top flange
housing all electronics feed-throughs (for sample wiring and temperature control)
fixed to a stainless steel tube which supports a sample mount at the field centre.

Rotation of the platform is done manually from the top of the probe.
A multi-turn knob with a calibration is fitted. An automated rotation motor is also available.
Positional accuracy of better than 1 degree may be obtained with the rotator.

The probe is fitted with 20 pairs of electrical leads for experimental use. A PLCC chip is used
as a sample mount. The PLCC chip mounts into the PLCC socket on the rotation platfor. The
wires from the rotation platform lead to a room temperature multi-pin Fisher connector at the
top of the probe. The sample platform is also fitted with a 30 point calibrated Cernox
thermometer (1.4K to 325K) and a small heater. Wiring for the heater and thermometer is
taken to a separate 6 pin Fisher connector at the top of the probe.
