The charge questions for the reviewers and the agenda is below Charge questions : 1. Are the technical performance requirements appropriately defined and complete for this stage of the project? 2. Are the plans for the various sub-systems appropriately documented and complete for this stage of the project? 3. Are the current plans for the detector likely to achieve the technical performance requirements, with a low risk for cost increases, schedule delays, and technical problems? 4. Are the schedule assumptions for the fabrication of the various sub-systems and assembly plans reasonable and consistent with the overall detector schedule? 5. Have ESH&Q and QA considerations been adequately incorporated into the plans at their present stage? 6. Have the recommendations from previous reviews been adequately addressed? Schedule (assigning speakers???) May 12, 2026 (TIME IN EST): 11:30 am : BTOF sensors (Satoshi) 12:15 pm : BTOF modules (Simone) 1:00 pm : BTOF service hybrid (Wei Li) 1:45 pm : BTOF integration (Andy) 2:30 pm : BTOF ASICS (Artur) 3:00 pm: Overview and requirements (Surabhi) May 13, 2026 (TIME IN EST): 1:00 pm FTOF ASICS. – 1:30 pm : FTOF sensors - Alex Jentsch 2:15 pm : FTOF modules - Mathieu Benoit 3:00 pm : FTOF service hybrid – Wei Li 3:45 pm FTOF integration. – Mathieu Benoit Best regards, Surabhi
