Dear All,
If this "5 cm request" is due to the "installation" of an additional tracking station, I would like to remind you that the best solution can be SciFibers.
I will need <1 cm in Z (compact), fast, low mass, and good tracking setup.
Best regards, Nikolai.
PS. It can be a rather "valuable" R&D and simulation activity, if the team (new, old) will stand up to prepare the proposal.

_______________________________________________Hello colleagues,
Not unexpectedly, as part of the ePIC e-endcap tracker optimization, the space allocated for the pfRICH was reduced by 5cm along the beam line.
Alex, please we need realistic estimates of the overall envelope for the pfRICH vessel, especially at Rmax, Zmin and Zmax. Remember, the v03 pfRICH GDML geometry was still in a "few mm overlap" conflict with the neighboring subdetectors, meaning the clearances may have not been observed strictly, even before this 5cm reduction.
Then we check with Chandra what the implications on the pfRICH performance are.
All in all, it sounds like we should discuss the incorporation of other possible pfRICH extensions (either pyramid funneling mirrors or a second aerogel layer a la Belle II or both) in the baseline configuration at our Thursday meeting, before the transition from mRICH to pfRICH is concluded in P6.
Regards,Alexander.
