New crew on shift: Guillaume Batigne, Pierre Moussiegt, Eric Voutier, Bodo Reitz
16:00 Sweeping Hall A in progress
16:43 Power permit
17:15 Beam permit
19:15 MCC calls, had problems with the injector and will startonly now to restore beam.... if everything goes well, we may expect beam by 20:30.
20:30 Update... after they solve the RF problem at the injector, they experience a "phase" problem and are now steering again >> in practice they are still at the injector
level, expect to pass it now at resume beam within 1-2 hours.
20:57 Pulse beam to the hall
21:29 Ready to send CW beam to the hall; MCC starts with low current to check the
21:35 Beam is on with 5 uA; start an HARP scan to check the beam spot
Harp run number 1791 ..... coda run # 1621 ..... 101 um x 57 um
21:50 MCC wants to try to go to 100 uA before we continue to tune the beam spot
since further adjustement may affect the beam spot too. Carbon target being in place
we start pointing meassurement at the same time.
21:59 Take beam for spot adjustement, we end with 69 um x 81 um and take this
beam spot for data taking
22:16 Start data taking
22:24 Move to 15 cm LD2 target
22:33 Beam is unstable / MCC check something in our line
23:52 Start taking data at 70 uA, the beam is stable there and they will try to increase
increase intensity over the next hour.
