Electric Field

We provide a sample stick for applying electric fields to a sample.
The stick is capable to handle high voltages of up to +-5kV.
Electrically floating sample mounting is possible, i.e. for charge current measurements.

The stick consists of a vacuum chamber containing the sample.
To permit multiple neutron scattering geometries with respect to the E-field direction, electrodes are either sputtered onto the sample, or painted on with silver paint during sample preparation.
For a reliable preparation we recommend to mount the sample 1 day before the start of the beam time.

Two sizes of vacuum cans are available

id	35	18
samp. len	59	55
sampl. mount	sapphire plate	sapphire plate
	63x23x1	60x14x1
