BTF-DAQ data specification

The BTF-DAQ is a dynamic composition of different modules, each one of those is run-time switchable on and off
Here is a standard configuration, with some modules in a VME crate, other in NIM crate and again as standalone:

  1. Delay Programmable Unit

  2. Scaler

  3. Silicon Microstrip chamber

  4. Peak Detector

  5. QDC

  6. TDC

For more info see this page

Here a sample of one line in output from BTF DAQ

This example datastream has: - SINGLE event mode: one event(ok trigger) per buffer - only one running board (QDC2)

Here an example row of the datastream (\n unix terminated): 1 73 0 0 0 1 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 16375 8471 0 10 18775 19964 42 314 134 1065 106 816 106 833 151 1180 134 1034 145 1168 30 251 131 1038 134 1076 159 1231 154 1232 146 1118 164 1262 141 1118 149 1182 0 -1697888 165123 1 1 1
