RAW file dumped by EUDAQ (stream from Labview)

EUDAQ dumps the complete stream from labview control. Labview adds prefixes to each packet in the stream to destinguish an origin:

  • 0xCDCD: ASIC data, temperature data, timestamps
  • 0xACDC: slowcontrol info
  • 0xDAC1: LED voltage
  • 0xBAD1: Bias voltage adjustment

EUDAQ RAW

type is "CaliceObject". responsible module: ./user/calice/AHCAL/module/src/ScReader.cc

Event parameters

(standardized EUDAQ)

  • EventN
  • TriggerN
  • Timestamp (range from - to, 25 ns bins) - typically filled with the complete bxid width, 

event block structure:

  • Block 0 (c_str): "EUDAQDataScCAL" - will be translated to the name of collection
  • Block 1 (c_str): "i:CycleNr,i:BunchXID,i:EvtNr,i:ChipID,i:NChannels,i:TDC14bit[NC],i:ADC14bit[NC]" - field description for slcio
  • Block 2 (vector<int>): time (unixtime)
  • Block 3 (vector<int>): slowcontrol block
  • Block 4 (vector<int>): LED information
  • Block 5 (vector<int>): Temperature
  • Block 6 (vector<uint32_t>): timestamps: start (Lo, Hi), stop(Lo, Hi), (trigger(Lo, Hi))++
  • Block 7 (std::vector<std::pair<int, int>>): stopping BXID per asic
  • Block 8 (vector<int>): HV adjustment info
  • Block 9 (vector<int>): (reserved)
  • Block 10 (vector<int>)*: block of BXID data from ASIC for all 36 channels (as described in Block 1
  • ... (same type as block 10)

  • LDATS_High - trigger timestamp in ns
  • LDATS_Low - trigger timestamp in ns
  • ROC - Readout Cycle
  • ROCStartTS - timestamp of start of the acquisition command (25 ns bins)
  • TriggerBxidTdc - trigger timestamp within the BXID. Can be 0..159 in case of 4us acquisition window
  • RawLDATrigID
  • (Dummy) "1" means a dummy packet to fill the sequence in case event number is used as a trigger number
