MTest Pixel Telescope Status Update

• David Christian
• March 12, 2008

2
Detector Status/Plan

• Hybrid development complete.
• 36 hybrids delivered, 4 more expected.
• 2/9 rejected due to readout chip failures (7/9
  78) suspect sensor bias wire bond switching to
  conductive epoxy for bias connection.
• Also have 4 old hybrids.
• May not have enough for 6 stations (yield
  required is 36/44 82). 4 stations should be
  easy (24/44 55).
• Module development
• Full production of 4x HDIs recd (plenty for 6
  stations).

Detector Status/Plan continued

• Plane/Station development
• Three planes being tested.
• 1 has a large number of bad bump bonds.
• Production rate expected to be 2 planes (1
  station) per week.
• Expect 2 stations complete by 3/21.
• Expect 4 stations complete 4/18.
• SLINK
• First prototype tested modifications required.
• Revised PCBs received 1st assembled board
  expected today (3/7/08).
• Delivery of ACTEL FPGAs will determine production
  rate
• 2 in hand now (1 PCB)
• 4 more in late March (2 more PCBs)
• 8 more in early April (4 more PCBs)
• Box/Area
• Mechanical design to be coordinated with needs of
  LHCb VELO (1st users).
• CM Lei has been assigned by PPD.

4
DAQ Status/Plan

• DAQ Hardware/Firmware (Nevis)
• PCI interface 98 complete (trigger/timing hooks
  not written)
• Router 90 complete (trigger/timing,
  implementation of merges not fully tested)
• SLINK (tbtm) firmware debugged without pixel
  modules 1st integration testing planned 4/1.

5
Software Status/Plan

• Online software (FNAL, Syracuse)
• Core low level routines exist have been tested.
• Development of the balance of the package has
  begun (1/3 done).
• On the optimistic critical path
• Offline software (Syracuse, FNAL)
• Data unpacking
• Alignment
• Tracking, integration of DUT
• On the optimistic critical path.

6
Schedule

• Slink integration testing 1st week of April.
• Install test 2-station telescope 3rd week of
  April.
• Install test 4-station telescope 1st week of
  May.
• Install test VELO sensors 3rd 4th weeks of
  May.
• Install test 6-station telescope as possible.
