Summary of the evening shift 04/07 4:00pm-12:00am

On shift, AT and WR

Very smooth shift:

Took over with run 5443 in progress

17:55 Martin Hu reported that the problem with the cooling was under 
      control.

19:05 end of run5443: beam current at 14.5 mA, integrated luminosity
      for this run is 266.7 nb^-1

20:35 and 21:55 Jet started clogging. Warmed up the nozzle (with some help 
      from Gabriele)

22:07 DAQ reset (but no problem)

22:40 Jet density regulation turned off automatically after reaching a 
      density well over 3 * 10^14 . Automatic regulation was kept off 
      for the rest of the shift. 

22:45 End of run 5444: beam current at 12.07 mA, integrated luminosity 
      for this run is 254.0 nb^-1. 

Summed luminosities of runs 5438-5444 are now 1.1857 pb^-1. 

23:00 Jet clogged up again. Warmed up the nozzle, and it back to normal.

12:00 am: run 5445 (still in progress) accumlated 71.5 nb^-1 sofar,
      i.e. we have a total of 1.2572 pb^-1. Beam current at the time 
      is 11.24 mA.
