The B1 station, as part of the National High Pressure Facility at CHESS, has been combined with B2 station to form a multifunctional high pressure station. This newly upgraded station is equipped for x-ray diffraction studies with diamond anvil cells, still capable of all kinds of measurements that the B1 station had previously.
The source for the B1 station is a bending magnet. The beam is stopped down to about 3 mm before entering the station. The beam is further reduced by a set of apertures to the final beam size of 5 to 500 microns. The final size depends on the requirements of the experiment.
The High Pressure Facility exists to provide experimental support for high pressure experiments with diamond anvil cells. In these cells, pressures from around 0.1 GPa (1 kbar) to well over 300 GPa (1 Mbar) can be generated. The facility has stages for mounting diamond anvil cells installed in the B1 hutch has been modified and permanently installed in the B2 hutch. It still enables high pressure measurement of Energy dispersive diffraction and some Laue experiments.
