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?

paper out on irradiated AC-LGADs from last year: https://arxiv.org/abs/2503.16658
We did another round of irradiation with neutrons on some AC-LGADs but at extreme fluence, plus another irradiation campaign with protons on the large AC-LGADs that should be ready soonish.
