DRAGON Group Meeting   3 June 2008

Present  DO(rec) CV LE PM SF LB DH

Hardware:
     
    NaI counters are now clamped down and be removed or replaced with some degree of precision.

    Gas target will be vented for test for signal for SB0

    There is evidence that we have dented the front face of two of the BGO enclosures.  Probably caused by crushing the
      preamp boxes as we close in the array.  Notice to experimenters, be careful when closing the BGO array.

    We a working pre scaler, probably need to repair the one we have as they are scarce.

BGO Efficiency
    
    Some discussion as to why is the efficiency so low?
    Due to Q10 off?  

June Running Plan

    Large group of experimenters here  (36 people)  
    Shift schedule should release CR, DO, SF  at end to run the 22Na.
    Need for a run plan and detailed instructions for e-log use

22Na Run Seattle

   CR presented resonance scan done on weaker 185 microC target
   Attached to minutes
   Represented 70 hours of running.    

22Na Implantation Plan

    CR has documented plan for safety
    JMP and GB are away
    Will discuss plan with Pierre B 
    DO will plan a LN2 system for the cold finger perhaps with a remote readout on the cold finger so we will know if the LN2 goes dry.
    Venting the collector box will be to dry nitrogen.
