Studies/Work Completed • Pbar only store (initial BPM & SBD issues. quench on abort: kickers not charged) • Plenty of proton onlys (orbits, tunes coupling, bumps) • • Tried new helix closure corrections Crystal collimator test Bumps through S 4 corrector elements TEL tests • Abort kicker inspections – bad crimp connectors found • Vacuum pumps replaced • 460 firmware upgrade Tevatron Coordinator - FNAL 12/17/2021 8

Studies • • • T-980 (EOS 2 -3 hours, Still) Investigate horz tune mult (Ron) Tune space study at collisions (source of differential coupling) Bumper magnet studies. TEL 2 optimizations for abort gap cleaning (EOS 1 hr) Tevatron Coordinator - FNAL 12/17/2021 9
