Folks at Yale (Fleming, Friedman, Johnson) invited a device to freeze
crystals while under xenon pressure in a pressure cell, avoiding the
limitation to release the pressure, remove the crystal from the cell and
freeze quickly as Xenon leaves the crystal.  The device has been
commercialized as the Cryo-Xe-Siter from Rigaku/MSC.
