Calorimeter Software Meeting - Tuesday, September 18, 2001

• Looked at SCA distributions
• New Zero Bias Run 131042 - 39904 events
• Pedestal Subtracted, non-zero suppressed

Many SCA daughter cards replaced throughout Crate 5 by Fu and Melissa
Comparison of distributions before (Run 127290 - August 5th) and after (Run 131042 - September 13th)

Shift in L2SCA for every channel in BLS.
Fixed it by replacing entire BLS card.

Bad BLS Card - Tried to replace SCA daughter cards - No major improvement
We later realized that ADC 7, BLS 2 was an L card
(in the readout, ICD is BLS 3, Tower 2, but in the electronics, it is BLS 2, Tower 0).
This card was replaced Sept 19th during a controlled access.
With a new run and pedestals, we should see an improvement.

• Replaced 16 SCA daughter cards and 1 BLS card.
• There is a marked improvement in all affected channels.
• Do we continue?
• I looked at the rest of the channels in Crate 5:
  Nearly one-third (126/384) of the total towers have one or many rather marginal to quite bad SCA distributions
  Some may have been introduced when other SCA and/or BLS cards were changed in Crate 5 during the supervised access of Sept 10-12. Most were previously there, but I focused on just a handful the first time.
• At least the following 39 SCA daughter cards SHOULD be replaced in Crate 5:

ADC 0, BLS 0, Tower 0	ADC 0, BLS 2, Tower 3	ADC 0, BLS 3, Tower 0	ADC 0, BLS 6, Tower 0

Problem with L2 bit in Crate 6. Doesn't work most of the time.
We got lucky with Run 127290, but not so with Run 131042 (below).
