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?

The DSC contributions are expected to be a substantial component of the effort. Please, discuss the matter within your DSCs and prepare 1 slide that presents the paper-planning of your DSC. Send me these slides by April 10th. At the TIC meeting on April 20th we will analyze and comment together about the merging planning. Thank you for your kind collaboration, Silvia
