FDC Update

CDC Update

  1. The gas lines and outer shell have been installed.
  2. The CDC has been reoriented vertically for stringing.
  3. So far rows 1-4, 13-16, 25, have been strung and 26 is in progress. There are 2 more straight rows to do after row 26.
  4. Between stringing sessions the techs are also making measurements of wire tension and practising soldering. Most wires are within 5% of the specified tension (30g).
  5. The production documents are being updated (nearly finished).
  6. We have to start work on the TDR updating.
  7. Naomi's latest resolution studies with the CDC protoype are here: CDC prototype latest Using a high threshold to find the peak followed by an earlier lower threshold to give the time gives much better resolution than using one threshold for both.
  8. Curtis asked about the new fADC, Beni and Eugene said that there would be a preproduction run of 20 which would be available in the spring.
  9. Curtis offered CMU's help with testing electronics.
