Building of EUDAQ 1.7 release continues. Challenge now is installing extern/libusb without internet and system privilege. Settled the new ESTB user 116PRA training session to be Tuesday 11am at Bldg 28-141. Carsten warned that Tuesday May/29 morning will be preoccupied with dismantle of previous experiment and moving concrete shielding.which may use up all access keys. Our access to ESA may need to wait until at least Tuesday afternoon.
May/29
8:00AM Mike Dunning installed the current version of libusb and Ben managed to fully compile EUDAQ 1.7 release.
10:00AM ESA on permitted access so that no longer needs controlled key access until we close the area for beam, but the tunnel area still sealed off due to the Cu dump inside for previous experiment is showing some residual radioactivity that needs a few more hours to cool off.

11:00AM Some concrete shielding removal still ongoing but target/dump removal will be reevaluated after lunch.
1:30PM New crew Vallary, Ke and Jason exercised the Caladium auto trigger test runs in the parking position. Caladium chiller water needed a bit top up.
4:30pm Update from Keith Jobe: "The target is removed, but that was not as helpful as expected. The copper target had decayed a factor of two from the morning reading to 160 mrem/hr contact, but now we were able to find that the concrete blocks are 70 mrem/hr at the target location. This is still high. Tomorrow the Test Facilities team will proceed as RWT-II with contamination protocols to remove the lead and steel bricks and then the concrete blocks. Once that is done, I expect reinstallation of the Caladium will be relatively easy."
