17:00 Anneal done, Prestart not successfull, we reboot every ROC and restart the RunControl.
17:10 - 17:40 Data taking
17:40 -18:10 MCC is working on injector (for Hall A)!
19:55 -21:50 System Check! Rephasing took so long!
Remark: The fastest way to center the beam on the SEM is to know that a movement of the beam spot by +1mm needs a Bdl change of +1000Gauss*cm on the last stearing magnet 3C20H or V for Horizontal or Vertical, 1mm to positiv x (the same for the SEM and 3H00B) would mean +1000Gauss*cm change on 3C20H and vice versa!
22:50 Paddle 8 Layer 2 (channel 30) has missing ADC's and TDC's! As the spectras are only filled if both TDC's are ok, either the left or the right TDC was dead since the outputs of the delay boxes which go into the TDC's were both present. Beni switched the left detector nr. 8 plane 2, connected to channel 27 of slot 18, to channel 41 of slot 18)! The right detector nr. 8 plane 2 was in channel 11 of slot 20, it was moved to channel 25 of slot 20! The discriminator inputs where moved from channels 26 to 42 of the paddle discriminators. The map file has been vupdated, new name is gen.map.22538!
Furthermore we seem to run into a network problem. Beni is now going to reboot cdaqs2, you can read more in the next shift summary!
