P371 In-Vacuum Scintillator

Friday 6 Feb 2026, 15:00 → 15:30 Europe/Zurich

530/R-030 - BE-EA Conference Room (CERN)

Present: Laurie, Philippe, Dieter, Vincent, Huagen,

• Candidate location in T11 between T11.MQNE008 (blue quad) and T11.MBXHF010 (green dipole).
• Located around S = 9m and experiment around 27m giving 18m for time-of-flight
• Likely KF 40mm flange to be used in T-shaped vacuum piece
• Vacuum piece will be ready from CERN ~end of May
• Installation foreseen during operation in June during best opportunity. Would take 1/2 day.
• Potentially high rate of 10^7 to 10^8 at this point in the line.
• Agreed not a SiPM to be used in this area due to radiation. Only conventional PMT.
• Cables should be prepared for ~25m. HV + Signal.

 

Actions

• Laurie - basic simulation for S = 9m to predict rate
• Philippe - 3D model of T-shaped piece to give to P371 team

 

Will meet on Friday 20th to rediscuss.

15:00 → 15:20 Discussion

• proposed location in T11
• proposed connection we will make
• blank and connection for scintillator
• confirm which cables will be needed
