Analysis

• Single SLAB @ LLR

  Vladik & Adrian

  • Effect of ambiant light and with flash light seen
  • Set-up Config
    • 2 slabs tested
      • SLAB #15 (with cover)
      • SLAB #20 (no cover)
        • with and without black fabric
    • thr @ 225
    • Masking done "by hand"
      • a few channels
  • Run config
    • Spill Length = 170ms
    • Continuous Current
    • 1/2h runs
    • Note
      • Config was first incorrect (TB instead of BT) → ILC mode (lim @ 5 ms)
  • Results
    • 2 distributions:
      • Peak left of mips seen
        • larger for uncovered one
        • without black fabric
    • rate = 0.05 Hz/cm2
      • ~ 2× expectation
  • DQ

    • Data Corruption
      • Type 7
        • hit bits ≠ on low/high gains
        • 6 / 10^4
    • NHits>64 = 0
    • List fo Histograms
    • negative == adc=4
      • Channels 44–47, ASIC 1 & 4
      • SCA = 0 & >0
    • Spill# ≥ 30000
      • was only 2nd part of data
    • check of hist plots
• Beam Test @ LAL
  • Set-up Config
    • 5 SLABs
      • IDs ?
  • Scan of Spill Length
    • Pbm if SL>2.85ms
  • Run Config 1
    • Spill Freq= 10 Hz
    • SL = 5ms
    • Results
      • Large noise peak seen at BCID = 2050
        • Amplitude ?
      • same in CC and PP mode
      • Why in BT set-up and not LLR Slabs
        • [ ] Test SLAB #15 in BT Set-up

          AI

        • [ ] Change BT Power Supply

          AI

        • [ ] Check FW version of SLAB #15

          JN

  • Run Config 2
    • SF = 10 Hz
    • SL = 2.5 ms
    • Data Corruption = 0
  • Run Config 3
    • SF = 40 Hz
    • SL = 2.5ms
    • Data Corruption = ??
  • Other checks
    • Injection of signal
      • Done for 1 SLAB (AI, JN)
        • Results ?
• SLABs readiness
  • SLAB #21
    • needed a resoldering
      • done by JN
  • SLAB #?
    • 1 bad chip
  • SLAB #13
    • bulky capacitor
    • doesn't fit in det
      • On top of structure
      • How to integrate it ?
        • Measure
