Tevatron progress Aug to Nov03, look in FY04

• Luminosity (average initial peak L)
• End of July (5 stores 2815-2826) L40.1
• End of Aug (7 stores 2934-2956) L39.9
• record L as of Aug.8 45.3e30 store 2824
• record L as of Nov.7 48.9e30 store 2887
• lifetimes of N_p dropped from 70 to 32 hrs , L
  from 12 to 9 hrs, N_pbar and eff-emittance same
  ( 30hrs)
• FY03 Integral 238 pb-1 (goal was 230 pb-1)

Highlights on Operations/Reliability

• FY03 goal of 230 pb-1 2 weeks before shutdown
• New helix gt500GeV to Seq.4 ? 2 ramp eff (Yuri)
• Lattice corrected at inj ? helps ?pi (Valery)
• Crate PSs problems (3 stores)
• 1 bckt off pbars (2 stores, 3 days) fixed
• High proton losses early in stores
• 1st inj damper ½ commissioned (JS, CYTan)

Tevatron Beam Physics Progress

• V4YA ramp helix commissioned (Yuri, Jerry, )
• series of lattice measurements, implementation of
  corrected lattice at injection (Valeri, Petr)
• direct ?-function msmnt QXR way off the model
  (AJ)
• b2 snapback news, no need in 6 ramps, etc
  (Pierre, Velev)
• calcssuggestions on octupoles/A0 sextupole (PI,
  YA)
• ? est 37-44 cm from L(?z) (VS), drift since Feb
  (Vaia)
• theory of instability and inj damper, recomds
  (A.Burov)
• SDA of high proton losses (Paul, Vaia, VS)
  still ??

Tevatron Diagnostics

• new BPM design progress(S.Wolbers,J.S.,M.M.)
• Cv,h from tunefitter works (Paul)
• new SBD ?l algorithm (Alvin)
• IPM reviewed, OKd (AJ)
• Bunch phase detector design started (Claudio, JS)
• HLS system moved to sector B (BINP, J.Volk)
• Strange 21 MHz pbar Schottky (Markus H.)
• FWs test/analysis in progress(S.P,K.Genzer)
• Abort gap monitor improved, unexplained study
  results (H.Cheung, S.P)

Next Two Months

• Operation/Maintenance
• Tev startup 7 days 11/18-11/25
• Back to gt40e30 mid-Dec
• Beam studies after the startup
• impedance measurements after shutdown ? explore
• larger N_p (PI, Bruce, )
• lattice msmnts after shutdown (VL, PI, )
• commission inj-dampers (JimS, Tan)
• possible studies to reduce high LOSTP (TEL?)
• P1/A1 rolls ? Emm at injection (DaveJ,Val,JA)
• 300W kicker to clean DC beam (CYTan, J.S)
• commission SL abort gap monitor (Harry, Stephen,)

7
Next Two Months Expectations

• Last time it was we are around 45-51 by Sep 8
  - we are at 49e30
• Over the next 2 months, I expect
• be around 40e30 mid-Dec
• possible improvements
• 10-20 more p due to reduced Lambertson impedance
• As the result, I expect well be around 45-55e30
  by Jan.8, 2003
