Top View

• RUN 39401
• 167 CSCs in readout
• All ME1/3 are excluded 13 troublesome chambers
• 18 DDUs
• Trigger LHC, single-CSC,
• 400K events per DDU

3
DDU-level

• DDU39 (RUI5) - only DDU reported critical error
  nearly 100 of events
• DDU22 (RUI10) got out of sync at some point
  (6 events reported errors)

4
Found CSCs

• One hot CSC - ME1/2/15

5
CSCs with format errors

• 6 CSCs with gt1 error rate (down from 13 from
  previous golden)
• ME3/2/02 - DMB Header Missing
• ME3/2/14 - CFEB-DAV mismatch
• ME2/2/04 - CFEB-DAV,
• ME2/2/08 - TMB CRC
• ME2/1/11 - TMB CRC
• ME2/1/12 - TMB CRC

6
Low TMB/CLCT Efficiencies

• All ME1 and majority of ME2/1 have low TMB/CLCT
  block efficiencies (50 and less)
• ME2/2, ME3 have TMB/CLCT efficiencies 60-80
• TMB configuration issue (resolved?)

ME3/2
ME1/2
7
No CFEB SCA data

• ME2/2/04 - CFEB3
• ME3/2/14 - CFEB3
• no SCA data (check timing or CFEB-DMB cable)
• also reports format error CFEB DAV mismatch
• low occupancy of comparator hits as well

8
No CFEB data

• ME1/1/09 CFEB2
• ME1/1/35 CFEB1
• (no format errors)

Comparators (ME1/1/09)
SCA Data ME1/1/09
9
Hot CFEB SCA Channels

• ME2/1/1
• Hot SCA Channel
• (Layer3, CFEB3)
• ME3/1/11
• Hot SCA Channel
• (Layer1, CFEB1)

10
Hot Comparators

• ME3/2/15 - CFEB5
• hot comparators
• (loose CFEB-TMB cable)
• ME1/2/15 - CFEB5
• hot comparators
• (loose CFEB-TMB cable)

11
TMB CRC errors

• ME2/2/08
• TMB CRC errors 6
• (origin unknown)

12
No Comparators

• ME2/2/15 - CFEB5
• no comp data (???)
• consequently, SCA data does not show up too often
  either

13
Strange SCA occupancies

• ME2/2/31
• Strange SCA occupancies gaps

14
HV Segments issues

• ME2/2/11
• Plane1, HV segment 2
• still low efficiency -- check HV
• (2 channels are replaced)
• ME3/2/29
• Plane1, HV segment 5
• low efficiency -- check HV
• (update Alex confirmed and fixed
• bent pin in connector)

15
Miscellanea

• Run 39384
• ALCT format errors
• after firmware update
• on ME1/3 chambers
• (firmware bug is fixed by Alex Madorsky)
• Please upload the
• fixed version to ALCTs

16
Summary

• Run 39401 is good
• Initial timing and configuration issues are
  resolved
• Attention needed for
• Low TMB/CLCT efficiencies (fixed)
• 4 CSCs with missing CFEB data
• 2 Hot SCA channels
• 2 Hot comparators
• 2 HV channels to be checked
• 3 CSCs need further investigation
• ALCT192 firmware bug (fixed)
