Combined WP12/WP13 meeting
Participants: Roberto, Sandro, Florian, Bogdan, Laurent, Dmitri, Benedikt, David, Jens, Javier, Alla, Ruben, Maximiliano, Tom, Markus, Tatiana, Ivana
- MUON developments (Florian)
- how to import the muon geometry?
- details on geo in AliRoot, classes, ...
- too many abstact/helper classes
- get rid of them moving to o2
- electronics to be replaces
- slat-geo to be redone from sratch
- many lines, constants, not well commented
- details on slat-geo in o2 and why better than before (AliRoot)
- JSON for parameters, very useful
- first use for geo application
- MFT uses xml
- how much overhead for parsing wrt c++? compare o2/AliRoot? did not compare yet
- JSON written by hand, can be transformed in c++ to speed up?
- likely timing not a problem
- how to compare geo with AliRoot and validate?
- macro to test, simulate particles xssing different material
- need to integrate geo in simulation
- first PR? or continue until all in place?
- better to be able to have hits before pushing
- estimate on timeline for that?
- hits, before end of May
- FIT developments (Alla)
- details on what FIT is
- FIT in AliRoot for performance studies
- FIT in o2, only T0+
- hits, xy distros, time
- hits, all photo-e
- digits
- PMT time of 1st particles
- gaus-smearing
- amplitude, sum of photo-e
- details on calibration
- details on reconstruction
- details on MC tune on data
- FIT (T0+) hits in o2 ready to use
- simplified digitisation
- V0 geometry not implemented in o2, in real life T0+ and V0 are geo-coupled
- MC tuning (Benedikt)
- what and why to optimise
- monitor steps in G3/G4
- many steps outside detectors, in cave volume
- calls to B where not there
- monitor steps in G3/G4
- steps in G3/G4
- G3 lots of steps outside detectors, G4 many less
- but G4 in general more steps -> more steps in sensitive detectors?
- current cave
- huge cave volume, compared to detectors
- can we modify cave to fit outermost detector?
- custom cuts/process settings
- recent fix in G4 VMC for interpretation of cuts, good to do further tests
- what and why to optimise
- AoB (Bogdan)
- tool to check material budget
