== Hardware & Electronics

— two scissor-lifts were not functioning well

— should be fixed today

— want to do a final survey

— can be done without obstacles using laser scans and movable targets

— will ask about targets, prefer to use ours because locations are known relative to other parts of STAR

— some sectors will be removed with proper tool (for aging studies)

— Systems shutdown, operations for the STAR Experiment have ended

== Software

— Gene is working on FXT SC calibration for the three energies that were run

— Yuri received question from PWG about p and p-bar mass position from BToF

— Yuri working on dE/dx for FXT

— need SC calibration

— some dynamics from last year (perhaps some gain reduction)

— need Au+Au from whole year of Run 25 to understand (need SC calibration as well?)

— Gene can work on that around mid-March

— also need new procedure for dE/dx since pion MIP peak cut in these data

— time scale will be longer (not weeks or a month)

 

== AOB

— may lose HLT farm in couple weeks

— need to find home for ~300 TB of work

— proposal to change to bi-weekly meeting time

— another proposal is to merge this meeting with the QA Board meetings on Friday

— one drawback is some focus on the TPC will be lost

— will maintain the TPC meeting for now (bi-weekly initially) and communicate more closely with QA Board

— Flemming mentions that data preservation should be discussed further and with more urgency with STAR management

— Richard added that preserving means of analysis (containers for example) is equally important

— NEXT MEETING: 26 FEB 2026

Best Regards,

  Richard
