f All Experimenters' Mtg - 2 Jun 03K. Gollwitzer - FNAL3 TeV Summary Fixes –T:HE17 Trips that caused quenches Bad cable connector inside of relay rack –Trim power supplies LLRF filter to remove 100Hz –Small tune changes at 980GeV stop pbars from being coherent Studies –2 studies looking at injection line matching and vertical dispersion –Lattice measurements at flat-top & low beta –Tunes as a function of octuple and helix separation –Confirmed that F0 lambertson is now largest impedance –Much checkout of ramps (coupling, chromaticity…) –BPM characterization

f All Experimenters' Mtg - 2 Jun 03K. Gollwitzer - FNAL7 Antiproton Source Problems –2 Lithium Lens replacements Most pulses (20 months of service); transformer went bad Installation error led to early demise of lens –Lens water system problems (conductivity cell & valve) –Bad AP3 shunt caused bad transfers for 2 shots –Water pump broke  lost stack Broke a dipole and 2 quad shunts Studies –Tunes across Accumulator aperture –Measurement of the Accumulator momentum aperture –Quad BPM study –Extraction lattice measurements –Fast stacking

f All Experimenters' Mtg - 2 Jun 03K. Gollwitzer - FNAL9 Attempt at Fast Stacking Stack cycle from 2.4 to 2.0 sec Stack rate remains the same Pbar production decreases Goal is to increase stack rate by shortening cycle time and decreasing ARF1 bucket area. The tradeoff: leaving more pbars on injection orbit

f All Experimenters' Mtg - 2 Jun 03K. Gollwitzer - FNAL10 Proton Source & SY120 Proton Source –LRF Tubes One of BNL spares delivered to FNAL LRF5 Rested when possible; has been replaced today Back to no spares –Concern with hot areas of Booster SY120 –Three studies periods Extract beam on $21 but no evidence of proton beam in P3 line See beam spray on P3 multiwires Magnet polarities checked during access Steering/alignment is suspect

f All Experimenters' Mtg - 2 Jun 03K. Gollwitzer - FNAL11 Narrow in P1 and P2; wide beam in P3 P1 and P2 wires P3 wires

f All Experimenters' Mtg - 2 Jun 03K. Gollwitzer - FNAL12 Study week + shutdown week = average week ? Quench – Beginning of ramp Shutdown Studies Investigation of poor pbar efficiency
