• Technical Progress• Project Status• Status Report for December ‘05


Technical ProgressTechnical Progress

• AP2, DB studies Dave’s talk

• Li Lens One each of PT-1 and PT-2 lenses will be filled and

the PT-2 will be tested on the test stand. PT-2 should be ready for beam in June.

• Rapid Transfers Many elements of the upgrade are in place (ramping

power supplies, BPMs) providing benefits to operations in various modes

Transfers without reverse proton tune-up tried many times last week with good results


Technical Progress (contd.)Technical Progress (contd.)• 2.5 MHz pbar acceleration in MI

Results from 2 pbar study periods promising: 86- 93% eff while tuning, ~ 30%

• Shows 100% efficiency and ~10% emittance growth in proton studies for relevant intensities and emittance

• May save 15% pbars now being lost in MI during acceleration and coalescing

– current scheme acc+ coalescing eff. ~85%, 80%

• better beam quality, hence expect lower losses in Tev and gain in luminosity due to smaller long. Emittance

• Overall expect >20% gain in peak luminosity • Contention on how to proceed. There was a recent review held by

McGinnis/Kourbanis. • McGinnis report: Potential for 5-10% in L.dt now• We should try a few shots before shutdown

Far less risky and far less complicated than trying to recover and recycle pbars!

Compare with many projects in pbar source each <10% gain


• MI BPM upgrade Most of the hardware designed, ordered or delivered First test system almost ready; will be installed in

MI40 next week, replacing the old system Full upgrade during and immediately after shutdown

• BLM upgrades Prototype system running at MI60 for ~ 3 months,

with PC instead of local control card. Control card + software under test

Production to be completed by 4/15, a month of testing followed by installation

Technical Progress (Contd.)Technical Progress (Contd.)


• IPM, OTR detectors One each installed in the Tevatron during the Dec.

shutdown. Now fixing some problems. Might have some data after the current shutdown

• Tevatron Electron Lens Good progress TEL-1 upgraded with new SEFT e-gun TEL-2 essentially ready for installation

• Tev ES separators Install in SD’06, 2 new separators and swap 3

existing separators (these were sparking at higher voltages when larger collision helix were tried last Fall.)

Possible AdditionsPossible Additions

• Chromatic Compensation in the Tev Lattice The mom. spread combined with chromatic error in

the optics lead to poorer beam lifetimes. Correct the chromatic errors by implementing new circuits using existing sextupole magnets

Benefits:• Improves beam lifetime leading to 5-10% L.dt gain• Allows Tev to be operated at a new working point near

½ integer resonance. This in turn allows more intense proton bunches to be used in Tev stores. Can lead to another 10% gain in L.dt

A review was held in Dec., 2005 Three versions of the hardware implementation and

cost estimates presented with cost estimates of $620K (v1) (whole ring), $220K (v2) and $107K (v3).

• Since v3 seems to provide optimal benefit and the most cost effective, we would like to pursue v3.


Possible Gains (Peak Luminosity)Possible Gains (Peak Luminosity)

• Pbar stack rate + aperture up by another 30% ?

• 2.5 MHz pbar acceleration 10-20% • More protons 230E9 ppb 20% • Chromatic Compensation 10%


Near term Reviews/Decisions (Contd.)Near term Reviews/Decisions (Contd.)

• Beam-beam effects in Tev Jan. 26, ’06

• Tev alignment SD’06 work Feb. ’06

• Pbar aperture SD’06 work Aperture: band-4 cooling tank arrays + DB extraction

kicker magnet (+ DB extraction kicker motorized stand) <7% gain expected; Lot of effort, Risky? Review late

• 2.1 Reliability Upgrades Infrastructure: 345-KV switchgear spares for KRS, MMS
