Letter from Cardman to the Reviewers
---------------------------------------------------------------------

Thank you for your willingness to help with the review of the plan of 
electronics for the GlueX/Hall D project at Jefferson Lab. I understand 
that you have already been contacted by Alex Dzierba, the GlueX 
spokesperson. The GlueX/Hall D project is a major component of the 
planned JLab upgrade to 12 GeV and it includes construction of a new 
beamline, detector and experimental hall. We are awaiting CD-0 approval 
but in the meantime the GlueX collaboration has been active on various 
R&D projects as suggested an earlier external review of the project 
chaired by David Cassel of Cornell. In anticipation of a full-scale 
"Lehmann" review of the GlueX/Hall D project we are reviewing various 
aspects of the GlueX design: calorimetry, electronics and tracking. We 
are asking you and Glenn Young to help with the review of the electronics.

The review will be held at Jefferson Lab on Wednesday July 23 and 
Thursday July 24. We propose to start at 8:30 am on July 23 with a 
four-hour presentation of the project and electronics by various members 
of the collaboration. That will be followed by an executive session (of 
perhaps two-three hours including lunch) after which you will meet with 
the collaborators to address issues that might require more infomation. 
We will close the first day with a dinner. The first few hours of the 
following day will start with the collaboration members addressing 
issues raised on the previous day. You will have the remainder of the 
morning to prepare a draft of your report. The final closeout - a 
meeting with several of the collaboration members and me will take place 
by noon.

I am asking you to concentrate on these aspects of the electronics:

o Is the GlueX electronic design sound? Are any special areas of concern 
  that deserve special study?
o Does the collaboration have a sensible plan for management and are 
  their estimates of manpower needs realistic? Also, do they have a 
  realistic milestones as we prepare for the Lehmann review and beyond to 
  construction?
o Are there any major items missing in thier list of R&D tasks? Is the 
  priority given to each appropriate at this stage?
o Are there technologies or developments which we have overlooked that 
  may allow cost savings and/or improved technical performance?

A tentative agenda for the first half of July 23 is included below. 
Please feel free to provide feedback on this agenda directly to Alex 
Dzierba. The collaboration will supply other written material to you no 
later than July 7. I understand that you already have received a copy of 
the GlueX/Hall D Design Report.

Please contact Rachel Harris (757-269-7255 or harris@jlab.org) for help 
with travel arrangements. Members of our staff will help with all 
aspects of the review and preparing your report.

I realize that this service is an imposition on your busy schedule and I 
want to express my appreciation for your help in this project.

Sincerely,

Lawrence Cardman
