FED hardware status

FED hardware status

• As of Sept 2005
• From J. Coughlan communication

FED Production (I)

• Progress is good. We are slightly ahead of the
  predicted FED delivery profile shown at last
  Tracker week. Now expect to start with delivery
  to CERN of 25 boards in October and 50 in
  subsequent months.
• Our special FED Test setups were prepared and
  fully installed at the Assembly plant in
  July/August. Their staff were trained by our
  engineer and are now routinely running the tests,
  although with some expert assistance from our
  engineer on request.

FED Production (II)

• The 1st batch of 50 FED boards was manufactured
  in August and are now under test. 48 have so far
  passed the Assembly plant tests. About 2 have
  persistent problems and will need some rework.
• 42 of the passed boards are at RAL
• 26 of these have now passed our additional tests
  (optical testing, TTC and SLINK).

4
FED Production (III)

• 4 have some problems which we are investigating.
  But there are no common faults yet.
• remainder are still being tested...
• Our general policy is to put any boards failing
  tests to one side and go back to them after
  testing the whole batch. Of course if we spot a
  systematicfailure we would halt production.
• The 2nd batch of 50 boards is now being assembled
  and should start being tested at the Assembly
  plant next week.

Transition cards for SLINK

• 70 cards have been manufactured and all tested
  ok.
• 35 of these are now at B904.
• (We have only 5 twin Slink kits _at_CERN to connect
  up to 10 FEDs)

Firmware

• The problems with VME Block Transfers with both
  CAEN and SBS are fixed.
• We are now improving the readout speed.
• There are many other firmware improvements being
  made Fake Frames, Spy channel, Zero
  Suppression Lite....
