This page collects the fraction of active channels for each detector. Numbers are representative of the overall performances in a given run period. They are based on information is collected for the weekly run meeting.

  • For Pixel Detector: During EYETS the pixel detector has been replaced. Total number of ROCs for the current one has increased to 29696 compared with 15840 for the phase 0.
  • For RPC Detector: During the EYETS the RPC system has been flushed with Argon. The active channel is lower then at the end of last year because of a small percentage of argon still present mainly in the endcap chambers, which is causing high current and preventing to turn on all them. We will be able to restoring the situation in 1-2 weeks.

  • For Strip Detector: Previous definition (in 2015 plots) accounted for channels not included in the cabling or masked in online. New definition also includes channels identified as out-of-sync or irresponsible by the backend electronics and as too noisy or inefficient for various reasons in an offline analysis

  • For RPC Detector: The RPC active channel fraction in April 2016 is 97.7%. This is 0.9% less than the November 2015. About 0.5% is due to chamber off due to gas leaks, HV, or LV problems and ~0.4% is due to chambers with opto-link/configuration problems. Between April and May 2016, commissioning activities have not stopped and we recovered 0.6% of active channels. Presently, May 2016, the RPC active channel fraction is 98.3%
