Pulsar Hardware Status (report from
E1) Ted for Burkard Aug.
15th, 2003, bi-weekly meeting
We have been busy

• Pulsar pre-production boards status
• AUX card status
• Taxi mezzanine card production status
• Pulsar alpha version of Muon interface path
  status
• Plans for the coming two weeks

2
Pulsar pre-production status? produced exactly
as the prototype design, no single design
change needed, but by a different vendor

• Good news
• 4 pre-production boards arrived two weeks
  ago,
• 3 of them have been fully tested within two
  days.
• it was just plugplayall interfaces
  tested.
• ? thanks to Burkards automated test-stand
  VME software
• Not so good news
• The company made Pulsar more flexible than
• design specification the thickness is thinner
  than
• spec (63 mil instead of 93mil)
• As a results, the boards work up to 80 MHz,
• but not at 100 MHz as the prototypes do.
• not so bad news the company admits the mistake,
• and will make four new boards free of charge
  soon

Pulsar AUX card status

• 5V version fully tested long ago
• 3.3V version was tested with Pulsar SLINK test
  tools last week
• ? Ready for pre-production in progress

AUX Card

Taxi mezzanine card status
TX
RX

• Production finished weeks ago, 40 fully
  tested
• Testing is somewhat behind due to the
  availability of
• Pulsar boards and crate (all four prototype
  Pulsars
• have been dedicated for muon path
  commissioning effort)
• Now with the new pre-production Pulsars,
• Taxi mezzanine card testing started again
• Mikko is already an expert with Taxi mezzanine
  cards,
• and he is taking care of the production
  visual inspection
• and testing in progress
• Note hotlink mezzanine cards productiontesting
  finished long ago.

Status of Alpha version of Pulsar muon path

• Hardware/firmware/software tested and works
• with cosmic runs for the full chain early this
  month
• muon fiber XTRP inputs? Pulsar ? XTRPList
  ?Alpha
• Had some problems with beam and can be
  reproduced with
• L2_torture runs firmware needs improvements
• work has been slowed down by other activities
• the known problems have been fixed in the
  firmware,
• now can handle L2_torture
• Burkard just left for vacation
• Sakari just came back from Finland ?
• Cheng-Ju is now running the show ?

7
Firmware needs for PulsarPC interface timing

• Two Pulsar PCs shipped from Upenn to B0
• soon need special firmware for timing study for
  Pulsar/PC

SLINK LSC

• Tomi has been working on improving Muon Tx
  firmware,
• now he has just started working on this
  firmware

Plans for next two weeks

• Finish Taxi mezzanine card production testing
• start AUX pre-production
• Pulsar muon Rx with (near end of store)
• beam runs (readout inputoutput buffers)
• IF all works, may(?) request for a special run
  for the
• full chain
• Pulsar muon online monitoring software ready
• Initial firmware ready for Pulsar/PC timing
  study
