TOF Preliminary Design Review (June 3-4) Room: https://bnl.zoomgov.com/j/1617546118?pwd=qNzxLqF8Q4Mj3RerAZdVSELzEgEQzV.1 From: Surabhi Tarafdar <stara@jlab.org> Sent: Wednesday, April 1, 2026 5:14:13 PM (UTC-05:00) Eastern Time (US & Canada) Subject: Re: TOF Preliminary Design Review Dear TOF DSL and DSTCs, The agenda for TOF PDR (60% design completion) has been finalized and will take place on June 3 and June 4 , 2026. 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???)
