Day Shift, Saturday, August 24, 2002

8:00 D. Lawrence, J. He, E. Clinton, S. Danagoulian on shift
     Called MCC to ask status. The Crew Chief informed me that 
     they tried tuning beam to us for 4 hours and were unsuccessful
     and so gave up. At this point, they are not planning any more
     attempts at giving us beam. Our only option is to talk with
     the PDL at the 8:30am meeting.

11:30 Mark talks to Roger Carlini (Program Deputy), Mark Pitt (Hall C
      Run Coordinator) and Jacques Ludwig (Crew Chief). Hall C just
      started getting beam, about a couple of hours ago. They are
      struggling with rate problems right now and are in the middle of
      devising strategies to diagnose and correct their beam
      steering. Apparently, beam cannot be established to Hall B
      without bringing down Hall C for the duration of the beam tuning
      exercise. Given their current problems, Hall C is not
      considering giving up the beam for tuning to Hall B right now.

      According to Jacques, the process of establishing G0 beam to
      Hall C was not done with simultaneous multiple hall operation in
      mind. In particular, the beams coming out of the injector for
      the two halls are not well matched. That means that a good tune
      for one hall may not be a good tune for another. There are some
      other steering magnets being used that interfere with
      higher-than-three pass beam. All of this happened in the context
      of poor general health of the machine for the past few weeks.

      For it looks like we need to wait for the situation in Hall C to
      settle down. Mark I. will contact Mark P. this afternoon to try
      to identify a window for another attempt at steering us
      up. Roger seems willing to do this if Hall C does not mind.
