Hi Todd, I believe the blue colour is caused by free electrons produced on irradiation (the size and shape is presumably v. similar to the beam and the colour will not spread beyond 1 um if at 100K) and these will be produced both in the crystals and the cryo solutions. I thought that it was described somewhere in the literature but I cannot find a reference, perhaps someone else knows? Best wishes, Matt.
