D10 - High pressure and Low temperature

A series of short movies showing how neutron experiments are prepared or performed. Some of these movies have an historical interest since they captured important moments in the life of the ILL.

Preparing a High Pressure and Low Temperature experiment

The neutron diffractometer D10 is a four circle diffractometer with optional 2D geometry with analyser. It is the 2D option which is of concern here.

The video below shows the setting up of an experiment in October 2001. The high pressure cell (a clamp) containing the sample is mounted at the end of the sample rod. This assembly is inserted in a liquid helium cryostat. The cryostat is then installed on the sample table of D10. Once the cell is pressurized and cooled down the experiment can start.

Note that, which such a setup, the sample is surrounded by a series of thick metallic walls (cryostat + clamp). This not too much of a problem for neutrons since the beam attenuation remains low enough not to impair the measurements.
