3. Run II PMG 1/19/06 Pushpa Bhat 3 Technical 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

4. Run II PMG 1/19/06 Pushpa Bhat 4 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

5. Run II PMG 1/19/06 Pushpa Bhat 5 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.)

6. Run II PMG 1/19/06 Pushpa Bhat 6 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.) Technical Progress (Contd.)

8. Run II PMG 1/19/06 Pushpa Bhat 8 Possible 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.

9. Run II PMG 1/19/06 Pushpa Bhat 9 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%
