SCIENCE BRINGS NATIONS TOGETHER
TB data analysis #2

Europe/Moscow

Summary from the previous meeting:

==> merging follow-ups

 * test with pulsegen: from the data taken - APV - no problem, VMM still gaps. No help for merging but would be nice to understand if it's CAEN or VMM problem.

       - Vitaly proposed to repeat the test having several (four?) channels of VMM receiving the 50us pulses ==> Kirill

       - Dima proposed to look also at the 10 ms input of VMM in the already taken data ==> Andrey

       - If something changed to VMM between spring and summer? - check the difference between BXID and GrayDecoded in the May and summer data ==> Andrey

      - is there any "quality info" in VMM data - dig George's slides ==> Vitaly

  * re-resynchronisation - Dima introduced an algo to find the beginning of each spill, seems to be working

     - finalize the algorithm ==> Dima

     - fix reference runs from May and summer to compare (the same straw/VMM parameters) ==> Dima, Andrey

     - evaluate rates (efficiency) for every step - trigger481, MM track candidates, merging efficiency etc, document in slides ==> Dima, Andrey

     - add control histos and printouts for the merging process

         (the number of successive missing 50us pulses, full info of fake pulses incl pdo) ==>Dima

     - make merging of 10 spills of the May reference run with both approaches, compare efficiencies ==> Dima, Andrey    

    - merge 100 spills of summer data ==> Dima

    - plot rough RT with the merged summer data ==>Andrey

 

==> slides for Stefano

    - write Stefano that the control histos will be on Tuesday ==> Dima

   - x-check Dima's plot for MM geometry ==> Vitaly, Kirill

   - add missing histos from the merging to the slides ==> Dima, Andrey

 

==> TIGER time-over-threshold - if we see saturation - Vitaly contacted Alberto but no reply yet

   - if no reply by Monday, ping Alberto once more ==> Vitaly

   - get Fe source at GIF++ to be able to work with it without Giuseppe ==> Katerina

   - if converged, test on dump with TIGER, Fe and a scope ==> Kirill, Vitaly, Katerina, Dima
