SPS testbeam:

• runs taken: 
  • HV scan on top/mesh and drift
  • X&Y scan
  • pions run at different intensity
• links:
  • run spreadsheet
  • data storage: 

    /eos/user/h/hcal/Documents/TestBeam2024/gddRun

• notes:
  • able to take very long and stable runs up to 1M events per run
  • tracker made of 2 Tmm plus the GEM one placed at the end of the calo structure
  • towards the end, changed the flex adaptors with PCBs one -> no dead channels; decided to change all the adapors for PS testbeam
  • MM-RM3 -> the plot sent via email done using only pad chambers; understood that the inefficiency on MM-RM3 is a misalignment problem
  • 

PS testbeam:

• runs taken:
  • X&Y scan -> reperformed after having changed all adaptors -> at a first look, only noisy channels and no dead channel
  • energy scan from 11 to 3 GeV
•  links
  • spreadsheet 
  • data storage:

  notes: 
  • energy scan runs performed adding the CTF clock in AND with the scintillators
  • RHUM & MPGDHCAL sharing the same trigger -> possibility to perform offline matching between the 2 DAQ system

What to look at (link):

• SPS:

  • Tracker: 2Tmm+GEM 

  • check the charge sharing / cross-talk for calo chambers

  • charge distribution (MPV) as a function of HV

  • cluster size Vs top/Mesh HV

  • spatial resolution Vs top/Mesh HV

  • efficiency (with tracker) Vs top/Mesh HV

  • efficiency (with tracker) Vs Drift HV

  • uniformity (for each position we need to recheck the alignment )

  • timing Vs top/Mesh & drift HV (must be done from the Tmm+GEM)

  • Pions run: charge distribution Vs Rate; efficiency Vs rate

  • muons Vs Pions 

• PS:

  • configuration to have similar MPV for all the chambers and high E-Drift

    • check the charge sharing / cross-talk -> double check nothing is changed wrt SPS, in the without absorber configuration

  • uniformity

  • shower:

    • number of hits Vs energy with data/MC simulation

    • charge/per pad / per  layer  Vs energy

    • re-run geant4 simulation to recheck digital and semidigital

    • timing

  • mips pion Vs muons PID

  • timing with higher flow rate

  • Rhum:

    • check clusters extrapolation

    • DAQ system
