Each puck holds 16 crystals. That amounts to 90 crystals for one dewar load . Considering a 280 or 360 degree data set takes 40 minutes to an hour at 2-5 second exposures . If every crystal diffracted ( sadly wishful thinking for our membrane protein world) , that would mean after every load you are all set for 90 hours of beamtime. During this trip we collected 13 datasets from 5 pucks . We did change out some of the pucks once . The beamline personnel are always on hand all throughout the beam time slot ( even at 3.00 am). In our case a lot of the pucks had some surface ice which they cleaned out for us if we were taking a dataset. I hear that this cleaning using liquid Nitrogen may also be automated so as to allow for remote de-icing of crystals A single dewar holds 5 pucks . Each puck holds 16 crystals.
