Problems • • D 1 SHP polarity switch popped its breaker; reset ok E 3 Power Lead 0 has gotten worse; 5 m. V from tripping St 7062: Quenched D 0 low betas at Seq 24. High He background confirmed at A 19 -half cell. Turbo installed. . Tevatron Coordinator - FNAL 9/30/2020 4

Lifetime OK on helix Store 7062 (Quench). 7057 (lum=327)

Studies/Work Completed • Continue testing auto chromaticity setup for shot setup. • Smoothed orbits between stores. New offline algorithm that will keep angles across IR constant tested. • St 7062: Tested new version of C 101 for vertical pinging. New version is faster and did see the vertical ping. • Before st 7066: Adjusted hor. Position at F 0 at FT, lowered ver. Chromaticity at Seq 23 and adjusted ver D 0 angle at Seq 24 & 25 in response to quench. • Turbos added to A 11, A 19. A 3 survey of feedcan. D 1 wet engine repair. • BBQ tune measurement system operational for proton tunes. Pbar tunes coming soon. • TEL electron cloud study. Tevatron Coordinator - FNAL 9/30/2020 6

BBQ vs 1. 7 GHz Note horz tune change. Vert 1. 7 GHz really noisy!

Study Requests • • • P 1 line Lattice matching study (not ready yet) Chromaticity Tracker (Dedicated Study - Tan) Bumper as abort gap cleaning. BPM re-cabling (between stores). Pinging studies to look at coupling at start of ramp. Also test Vertical Pinger • Low Beta lattice study • TEL electron column study
