Simple devices for pressurisation of crystals under rare gas atmospheres at synchrotron beamlines

At the EMBL Hamburg Outstation and Elettra devices are available to the user community, which allow flash cooling of crystals pressurized under xenon and krypton. Experience and preliminary tests using porcine pancreatic elastase (PPE) crystals have been carried out.

We found that a procedure using 40 bar pressurization for around 1 minute to be generally effective for xenon derivatisation. A number of the beamline support staff has been trained in the use of the devices so that access for users is now routinely available. Over the two years that the devices have been available to the user community there has been regular usage of the facilities, usually on projects where all else has failed.
