3. fDIRC detector holder:  [version c]
4. fDIRC detector frame drawing to affirm:  [version c]   [version d]
   
5. potential placement of parts on H8500 front board

Information from Taiwan colleagues on Altera to Aurora connection:

Preparations for scanning set-up deployment visit.

Updated documentation below.

Touching base -- behind schedule on getting next board stack together.  Schedule first modules delivery once get back from iTOP cosmic ray test.

Drawings sent:  [version a]   [version b]

1. There are 2 classes of H8500 tubes:  1kV --> 1.1x10^6 gain, 1.1kV --> 2-3x10^6.
2. According to the HPK data sheet, the divider current is about 173uA at 1.1kV.  (so Jerry thinking to gang 3x together from Bertan HV supply)
3. Jerry will request quote for additional H8500
• Gary will forward this quote, to try and get PNNL to cover
  
4. Send H8500 tube in Hawaii back to Jerry
5. In return, Jerry will send one of the new, tested H8500 for integration tests in Hawaii
6. First priority will be to get scanning system module readout working first, which entails
• Designing and fab appropriate Front card
• Additional cards (SCROD, interconnect, L1-L4, BLAB3A ASIC) dedicated to fDIRC
• Qualify performance with H8500 tube
  
7. fDIRC fBlock to SLAC by July, assy in August
8. Final module mechanics to be sent to SLAC when available
9. Items to resolve for deploying full complement of BLAB3A board stacks in CRT:
• Power supply for SCROD modules
• Brackets and cabling mechanics

17-JUN-2011:

Drawings from Jerry:

• Previously proposed image plane scheme: [pdf]
• New scheme to accommodate later arrival of Wavecatcher electronics: [pdf]
• New H8500 connector & pin mapping: [pdf]
  

Discussion points/questions from Jerry:

• Can BLAB3 electronics package fit within H8500 profile?
• Older version of H8500 tube is in Hawaii, send back to SLAC?
• Plans to provide realistic BLAB3 package for scanning setup?
• Fiberoptics still needed at new setup?
• Fiberoptics are still required, 1 per electronics package, which services 2 H8500 PMTs.

Image plane concept drawing from Jerry, with BLAB3 module superimposed:  [PDF]

Clarification on module width:  the boards are 100mm in the direction shown,
and the width will be determined by the thickness of the aluminum side plates
(which also serves as a heatsink) and the depth of the slots.  However, the
clear boundary condition is to meet the H8500 [PDF]  104mm + spacer (1-2mm?) between tubes?

Of course for this first configuration, could be wider, though it would be better
to keep the footprint small enough that it can continued to be used later, when a 
full matrix is packed together.

Gary will be in transit and cannot make meeting.  Kurtis will post an agenda/slides?

Summary figure from discussion last week:  [PDF]

Agenda

1. Summary of number hits in new data?
2. Processing status?
   

There will be a meeting to discuss options for a new PMT/readout holder on image plane.
