Intro:
- no questions
- I will check this implementation with Tony’s new signal files once these are ready. In any case this is a tentative solution until we get the insitu measurement of the field map.
- then need to just decide on the field strength itself (probably 1.6 T for BPPP and 1 T for Trident)
Tony:
- lots of changes and as few bugs were found —> validation now checks out: effectively no difference within stat errors
- should get the Brems' from Sasha for the BPPP sim
- should check also the Comptons but the fact the positrons behave well is indicative also that the photons are fine
- please change x-axis to intensity rather than pulse energy or spot size
- will detail all changes formally later
- jobs should be done this week
Sasha:
What needs to be implemented before launching (by the end of this week ideally):
- calo geometry from Maryna for the IP system (including a simple box/crate)
- merge John’s branch for the upstream system (can be done by the end of the today)
- fwd photon system:
- add collimators as in Gianluca’s drawings
- change to a Kapton foil at the end and the collimators (ending the beampipe’s vacuum and serving as a target)
- “copy” the Cherenkov + screen implementation from John’s branch to the fwd photons system (replace the tracker+calo which are there now). Please check what’s in the step file from Oz - the Cherenkov should be fully implemented there (TBC with Ruth)
- distance between the end of the beampipe (Kapton foil) and the back of the calo of the IP detector system should be smaller. It can be easily moved by ~3.5 m upstream. If we do that, also the detectors should move upwards).
We will discuss on Thursday again
What can be implemented before launching but not if we didn’t finish the points above:
- stage + optical table for supporting all components (important for background but secondary)
- add the non-perfect B-field
Else (not high priority):
- give Tony the Brems' spectrum so he can launch the BPPP jobs
- need input from Noam for the materials distribution in a stave (not high priority)
- Arka needs the tree to start looking on the interface to the KF code
There are minutes attached to this event.
