Intro:
- e+laser: need another beam-only production
- implement Florian’s dump for now tentatively and we study the result of the
Beate:
- assume 1e7 sec per year nominally (in 2019 ~40% of the year beam time, then 80% data taking efficiency)
- what is the fraction of time where we have the the nominal beam?
Tony:
- waiting for brems’ —> Sasha is validating and will provide the input files before the weekend ideally so Tony can run the jobs over the weekend
Sasha:
- s6: what’s the distance between the
- what is the x value in the table for the calo?
- 1 GeV cut is maybe too loose maybe, just because these won’t exit the dipole in the signal
- point about the segmentation of the lysos compared to the tracker…
- we do also measure the electrons with the Cherenkov
- air scattering is not a problem?
- can do the dose plots for the sensitive parts
Kyle:
- previous hotspots are just artefacts of plotting
- change to LANEX with higher light yield (otherwise very similar to lysos)
- need to verify the radiation hardness —> need an answer this week
- segmentation can be much finer than what we consider now for the lysos
- take the data from Sasha to do the deconvolution after Sasha gets it running?
- profiler:
- segmentation can go to less than 50x50 um2
- rad-hardness is still a question
- need to make sure if it is possible to place it after the shielding without ruining the backscattering calo measurement
- check can we remove the inner part of the profiler to cut the core of the beam - will that ruin the measurement?
- Awake are using Gadox (how much rad-hard?)
- FLUKA:
- geom converted from G4
- already did e+laser tests which look reasonable.
