Measurement of current drawn by DT chambers as a function of LHC instantaneous luminosity


  • The currents drawn by DT chambers were measured during LHC operation, Fills 2683 to 2728. The currents were read from the DT HV modules CAEN A877.

  • The shown values were obtained by averaging the currents of all wires and layers of a given chamber for 10 minutes. The current measured for the same chamber in no-beam conditions was subtracted from the result.

  • The results are plotted as a function of LHC instantaneous luminosity, as read from the LHC Operation Page.

  • The highest values of currents were found in YB+2.

  • For each wheel, MB1 currents were found to be Phi symmetric.
