This is one of the frames from the first dataset collected at 100K with the Cryojet system, overnight. Some rows of diffraction spots can be seen, along with some scattering around the direct beam that comes from a little ice build-up on the crystal.

First 100K, now high pressure. One of the diamond-anvil pressure cells of the ETH design mounted on the Xcalibur 2 system.

The first task after mounting a pressure cell is to drive the goniometer around and to check for collisions between the bulky diamond-anvil cell and the other components of the diffractometer.

One of the challenges in obtaining diffraction data from crystal held at high pressures inside of diamond-anvil cells is how to measure the diffraction intensities from the crystal (sharp spots) in the presence of strong scattering from the components of the pressure cell. The powder rings come from the beryllium backing plates.
