WP2: Status meeting #25

Thursday 19 Jun 2025, 15:00 → 16:00 Europe/Zurich

874/R-018 - salle de réunion activité CCC (CERN)

- integration:
    - small change needed for distance between MTNs
    - survey files ready and will be provided to Fred this week
    - new sequence will be updated in acc-models-ea
- Survey:
    - need to discuss with Patrick and Camille to how we re-align the elements 
    - all the splitters will be moved and out and in in LS3
        - we need to know where to put them back
        - can we put them back where they were? 
- Sequence:
    - ± 30 mm for the aperture of the TAX
    - sequence to be updated for the optics design (Fabian)
    - also instruments in the survey and integration done with new BSGs in TCC2
    - Laurie to check if all instrumentation in P42 is IN-OUT
    - Matt to check with Anthony the thickness of the vacuum window at the splitter
    - Laurie discussed with Miguel for the vacuum - Miguel will present at the next meeting
- TBIU specification 
    - Laurie confirmed that BI can do the BSG with off-set for Hi-ECN3
    - Francesco to finish TBIU doc with specs for BSGs for other lines 
    - Fabian to add gitLab link for the latest beam trajectory in TBIU
- BLM
    - BLM robotic solution being validated in the lab - soon to be finished 
    - Matt and Francesco to make a very short specs to put in confluence and the Christos will add this to specs
    - Christos explaining that if the timing is missing at some point, they will use a "fail" user. Basically there if the info on the user does not come, that user will be used and a dump will happen. 
- Dipanwita share a list of points that will have to be discussed before the NACONS review
    - 24th of July review - need to check before
- Dilution sweep specification (Matt)
- Johannes is looking after the LOKEN
- Matt sent the list of requests to EPC for the requests that we have 
- BDSim model of P42 available to assess background 
- SHiP target diameter above 250 mm does not change much 
    - for 16 mm beam size 
- Error studies once optics is available 
- Results available on the use of orthogonal steering for TT24 - discussion needed with Thomas and Philip to agree on the need for laminated correctors in P42 or not

15:00 → 16:00 Round table

P42 optics rematching
- list of constraints
- quad position knob
