Present: Flemming, Jim, Yuri, Gene, and myself

== Hardware & Electronics

— Survey is not complete as far as we can tell

— Schedule for actual removal of the TPC may be months not weeks

== Software

— Gene will being Run 25 SC calibration as soon possible

— otherwise to do list remains largely same as last meeting

— Gene mentioned disk space was provided for Yuri’s work 

— ~135 TB 

— Yuri working on dE/dx 

— sample from beginning of Au+Au

— sees definite evidence of aging effects

— has preliminary version of calibration, but not yet satisfied with it

— in FXT data sees higher dE/dx than predicted by model (mostly in 1/beta^2 region)

== AOB

— JH says we will have survey no sooner than 2 weeks from now

— Yuri would like to know the weight of the FST materials once they are removed

— Flemming work on adding FST 

— cable trays have been added but do not have content yet

— actual trays are about 5-6cm longer than engineering drawings from 1997

— Yuri mentioned that beam pipe support may be quite different than what is in drawings

— changes after HFT was installed and later removed

— TPC aging study 

— need to socialize which sector(s) we would like for the study 

— NEXT MEETING: 23 APR 2026

Best Regards,

  Richard
