Live Time

  • The computer dead-time (CDT) occurs during the process of writing the experimental data into computer disk.
  • CODA stores each event by its trigger type separately and controls the recording rate by adjusting the pre-scale factor (PS).
  • Then the computer dead-time is defined by comparing the number of events stored in the computer (Ntrigger) and the number of pre-scaled raw trigger events (Ntrigger/PS), which is recorded independently in the scaler information:

<math>LT = \frac{Ps*N_{stored}}{N_{triggered}}</math>
