XRM Readout Working Group

• Fabio short-report on detector support [link]
• Fabio Rinaldi thesis [link]
  
• SLAC Detector meeting prep (14-JUN-2016)  [pdf]
  
• 
  
• First x-rays on LER beamline  [pptx]
• Online Operators Log (requires KEK VPN/tsubaki access) [link]
• External accelerator status  [link]
  

• Readout box internals  [jpg]
• Detector under test (prior to shipment)   [jpg]
  

1. Detector Boards 
   
• Channel mapping (updated 23-JAN-2016)   [xls]   [png]
  
• Reworked, tested boards available (3x); need proper Serial Numbers added
  
• Working on channel mapping (Luca), definitive bonding diagram:  [jpg]
  
• Housings machining:  to be done (1x partial from before)
  
2. Amplifier boards
• 3x Assembled, shipped on Sunday (here either today or tomorrow).  Plan to install all 3, so 48 channels total
  
• Curtis done with shields -- ready
  
3. Boardstacks -- rework in progress
• Matt has done the first 1x Carrier.  As Tri-L wanted $1,100 (unreasonable) and they might not make it in time, Matt will just do so.
  
• He notes that another TJ-Hooker needs to be prepared
• Also, since we'll be using 3x Carriers on the JTAG programming chain, their traces will need to be cut
  
4. Readout Housing
   
• Steven is machining the boxes (approx. 75% complete);  Chris may ask Curtis help with the Front panels, which require quite a bit more machining
• Baseplate needs machining
  
• In principle have all parts, cable, connectors in hand for assembly/integration
  
5. Power boards
• Both boards assembled
• Some cabling work still needed
6. XTD boards
• 1x XTD now PLL working
  
• Both XTD need to have JTAG debugged
  

Next meeting:  Friday @ 2pm HST (1/22)

Other Items (next few days?):

1. Register other r-Pi on network
• Khanh will send MAC address
  
2. Try powering up/network connecting 2 SCROD in D8 Optics hut
• Next week
  
3. Set up EMI antenna(s)
• Bringing log-periodic (400 - 1100 MHz), should get VHF/UHF pick-up (locally?)
  
4. Be proactive in preparing EMI mitigation strategy
• Continue the discussion
