  2. Store Numbers Tevatron Coordinator - FNAL

  3. Store Summary Tevatron Coordinator - FNAL Tevatron Coordinator - FNAL 1/5/2020

  4. Integrated Luminosity for the week Tevatron Coordinator - FNAL

  5. Particle Intensities Tevatron Coordinator - FNAL

  6. Luminosity Lifetime Tevatron Coordinator - FNAL

  7. Earthquake near Baja F0 beam valve air leaks from solenoids QDD1 Tripped on Quench; installed new quench cards and recalibrated SF6 leak from E48 Minus pulser Vacuum bursts from C17 and B17 separators at Flattop D1 LN2 regulation appears to affect D1Q3 motion Transverse emittance growth of pbars at Collisions and Protons at Flattop QDD1 turned off during wet squeeze quenching D0Q3 Problems Tevatron Coordinator - FNAL Tevatron Coordinator - FNAL 1/5/2020 7

  8. Quad motion and LN2 Tevatron Coordinator - FNAL

  9. Proton Emittance growing at flattop Tevatron Coordinator - FNAL

  10. PBAR tunes when excited • This shows upper pbar tune at .5798 and lower at .5938. Is this a tune or coupling issue and do we need a pbar only store? (Later Jerry changed SQ and lifetimes improved) Tevatron Coordinator - FNAL

  11. PBAR non luminous lifetime and SQ changes Tevatron Coordinator - FNAL

  12. D0 and B0 bumps; F0 V-bump +0.25mm; no pbar long blowups since SQ changed to improve pbar non luminous lifetime Installed new BPM software at B3; had to revert as B3 BPMs did not have any data for the proton only stores and the data from Store 8194 looked erroneous. Beam synch cable for D1 BPMs was changed ; no reboots since change on Tuesday Studies/Work Completed Tevatron Coordinator - FNAL Tevatron Coordinator - FNAL 1/5/2020 12

  13. Studies Request • BPM code test (In store, Meyer & Voy) • Alpha Bumps at D0 • EOS: T980 crystal collimator (Still) • TEL2 hollow electron beam (EOS) • Proton Only to investigate spikes in tune spectra during a store? Tevatron Coordinator - FNAL
