14:40 Problem with linac injection source from power outage. Morning spent fixing it. Beam being tested currently in stages through the transport line
16:30 Beam coming out of linac, but still not seen further down transport line
19:00 Beam only available for maximum of ten seconds. Issue with the interlock system will be fixed on Friday
Foil mounting still troublesome. Double layer appears to work, but single layer not. Main grip is surface tension, and the foil holding its own weight as it is being extracted from the water.
