TB data analysis #38
→
Europe/Moscow
Description
run 163
full acceptance FEI4
timepix caen 1.8 M
azalea triggered 2 M
timepix and azalea ~570k tracks (Sasha's reco)
azalea reco (Artem) ~500k events with track
we expect ~250k tracks within straw acceptance
Dima -
- double tracking in Artem's method is fixed
- update azalea reco for double counting corrections + info total events, number of tracks (single track events)
- write to DUNE about available run
- still problem with merging 163 - Sonja will use caen-timepix-azalea merging at the moment
- still problems:
- time merging for 163 - do we need to try fix time merging? From which time triggerID was fixed?
if we don't need time merging - forget about it and use caen-timepix-azalea
- shift in coordinates Artem-Sasha - plot timepix residuals from Artem's data
then fix the problem (Sasha's help needed)
Sasha
- FEI4 is not used for neither reconstruction nor alignment
- update aligment table to discuss next time
Sonja
- page 3 - pls add fit - very largde sigma_t of the straw??
- page 5 - left plot - two tipes - for cherekov tag and for cherenkov veto
- update analysis for caen-timepix-azalea merged sample (RT, Landau)
Natalja
- 11% efficiency?? 87% events do not have ch0 ON - Dima: because of test pulse
- correlation dT and pdo_hit, and dT and pdo_ch0
- if no correlation => cut on dT~20 bx
- next step - selection on dT (and may be pdo?), and then clustering
There are minutes attached to this event.
