[PRad] Fwd: Re: Beamline Configuration Drawings for PRAD II, X17 and TFF

[gasparan]

   Hi All,

  As you see Bob wants to fix the engineering drawings for the 
experiments. We are
  equally interested in finalizing this part to start the procurement and 
construction
  phase.

  There are few items still not finalized on this part, let us try to 
work on them before
  this Friday meeting, discuss them there and answer to Bob.

  1) veto scintillators thickness: we are testing them now but, it will 
take another week
     if not more. I will contact Youri to see if this is important for 
the engineering design
     part.
  2) Veto scintillator attachment tolerance: we are working on this item 
but, it will need
     again a week or so. I will contact with Youri and Dipangkar to see 
if a 0.5 mm tolerance
     is realistic (for both edges of a single scintilator). In all cases 
we need survey ponts
     on this device.
     Weizhi, please make this item a priority before the weekend. If we 
need one more meeting,
     I am ready for that.
  3) Changing the vacuum window from X17 to PRad_II experiments (as it 
was shown by Bob).
     This is highly undesirable since it will involve not only the vacuum 
part (that comes
     from the target change also) but, it will require a new survey of 
the HyCal.
     If we decide to run PRad-II with the new (smaller) window, then the 
Pb-glass part of the
     HyCal no longer in use (if even it is ready).
     Weizhi and Chao, please take one more look on this part to before 
the weekend.

  4) What else is there to be discussed???

  Thanks,
  Ashot

  Good Morning All,

  Are there any comments on the layout of PRad II and X17, or do we
assume the design is fixed and we can finalize the drawings and prepare
to order parts?

  Thanks,

  Here are the beamline drawings for PRad/X17/TFF.
  Please review and give your feedback by November 15th.

  Eugene,

                  I have attached .pdf’s of the Preliminary versions
PRAD II, X17 and TFF Beamline Configuration Drawings.  Can you please
send these out to the individual run groups and request comments by
November 15th?
