Practical Information

North Area

info copied from 2016 test beam:

All practical information for users of the North Area can be found in the North Area Handbook.

The layout of the H8A area can be seen in the EHN1 experimental hall drawings.

The area is approximately 6 metres wide and the height to the beam line is 50 inches (127 cm).

Access to the area

Aim of the Testbeam

1. see clusters correlated to tracks from the half-ROBs.

2. Hit-efficiency for (sorted with priority):

  • different thresholds at one position (close to mirror)
    • planned for the low standard thresholds, we try to simulate
    • higher thresholds before to see which would be useful
  • threshold scans with tracks not feasible, LY too high
  • whole width of this mat (LHCb x)
  • one position in each mat (still close to mirror)
  • three positions along one mat (along fibre direction, LHCb y)
  • different angles one mat, one position
    • not as easy as it was in the past, but should be possible: 0, 5, 10, 20
  • one position different over voltages (lower PDE up to 50%)
    • different over voltages planned, but probably not possible to lower
      pde significantly (not possible to measure gain anymore)
  • this + different thresholds
  • all of this for all mats...

MiniDAQ2 Data Format

The MiniDAQ2 output ROOT-files contain the following information (extract):

1. A directory "Geom" with one TTree per module, i.e. ROB0 and ROB1. These trees contain the branches:

  • ROB_ID: ID of this ROB (0 or 1)
  • Orbit_ID: NOT FILLED HERE PROPERLY - DO NOT USE!
  • Evt_ID: The index of this event. Counting up during filling.
  • Fragment_ID: Counter from the TELL40 assigned to each fragment. Should match with Evt_ID!
  • BXing: Bunch crossing ID. Range: [0,3564)
  • ConsecBXing: Counter for incrementing BXing (reset to 0 when not incrementing by 1) - especially of interest for TAE data
  • absBXing: NOT FILLED HERE PROPERLY - DO NOT USE!
  • Time: NOT FILLED HERE PROPERLY - DO NOT USE!

2. In case where the new MD2 firmware with ODIN information was used (runs 30434 and above), an additional tree called "ODIN" with branches:

  • UTC_TIME: UTC timestamp in nanoseconds at start of run and then incrementing in steps of 25ns... BETTER USE absBXing AS TIMESTAMP!
  • Fragment_ID: See above. Should match with Fragment_ID of ROB0/1!
  • Orbit_ID: Orbit counter (1 Orbit = 3564 BXings)
  • BXing: see above.
  • absBXing: Calculated as Orbit_ID*3564+BXing. Can serve as timestamp (25ns per step)!
