16:00 Still waiting for beam.
21:00 MCC is going to change the Hall A status from controll access to beam
permit and send the pulsed beam to Hall A. The beam polarization is lower now, 61%
because they changed the gun with a new one.
22:21 MCC is ready to send beam to Hall A.
Change target to LH2 15cm. Reset trigger (T3 ignores aerogel)
22:54 MCC said the maximum current which can be sent to Hall A is 55uA.
Ask MCC to send the maximum current to Hall A.
2330 checked trigger signals with beam. Found that S-ray signal remains
well centered within aerogel signal.
