Revision as of 04:28, 4 September 2019
Here is reported the current status of Layer-2 electronics. Dead, noisy, strange, disconnected channels are listed with their explanation (when possible). The behavior of each TIGER of each GEMROC is reported, as well as the FEBs that show some issues and should be investigated.
Strips analysis[edit | edit source]
In this section, the status of L2 is analyzed from the strips point of view. This allow to spot the holes due to microsector (in order to remove them from the problematic channels) and potential zones of high noise channels.
- The strip annotated with "microS" show low charge and fewer hits due to the micro-sector geometry. This has a periodic pattern (one each 15-16 strips) and is well known.
- The strip annotated with "almost no charge (VERY LOW NOISE: DISCONNECTED???)" have very few events and very low charge (<5-10 fC) --> this has to be understood
