Run II Upgrades Status Report for the month of Dec Nov ember 2005 JanuaryDecember 241, 2005

1. Summary

The Run II Upgrades are 820% complete, as of DecNovember 310, 2005. 82 of the 106 A, B and C Class milestones have been met. Phase-3 of operations started on October 3, 2005. The upgrades plan washas been revised, re-baselined and theupdated in version 4 plan was released in December.

On November 5, 2005 the initial luminosity reached a record 167E30 cm -2sec-1. The rest of the month continued with smooth running until the Tevatron was off beginning November 22nd for a three week period to replace broken magnets. During the Tevatron repair period the Optical Transition Radiation (OTR) and the Ion Profile Monitor (IPM) detectors were installed and are now in the commissioning phase. During the three week shutdown in late Nov. – Dec. ‘05, studies were focused on centering the beam in the AP2 beamline and the Debuncher, and optimizing orbit in the AP2-Debuncher injection area. A number of instrumentation and ramping devices were commissioned and lattice measurements of AP2 and Debuncher were done. A 15% increase in stack rate has been seen as a result of this work. The studies have continued using other opportunities.

During the Tevatron shutdown in December, studies of the 2.5 MHz pbar acceleration scheme in MI were also done with both protons and pbars. The scheme, if implemented in operations, has the potential to essentially eliminate the pbar loss (10-15% currently) and the longitudinal emittance dilution (>80% currently) in the Main Injector for Tevatron stores. It can provide better quality pbar bunches with smaller longitudinal emittance and smoother profiles providing additional benefits in the Tevatron. The project has been declared successful and the operations department is expected to implement the scheme when higher priority issues are taken care of.. A proposal to implement compensation of chromatic errors in the Tevatron was reviewed in December. Currently, the momentum spread combined with chromatic error in the Tevatron optics lead to poorer beam lifetimes. These chromatic errors can be corrected by implementing new circuits using existing sextupole magnets. This is expected to improve beam lifetime leading to 5-10% gain in integrated luminosity. This chromatic compensation will also enable the Tevatron to be operated at a new working point near ½ integer resonance. This in turn allows more intense proton bunches to be used in Tevatron stores. The M&S cost of this project is about $110K and the project will be completed by August 2006.

Since the pbar source was still operational during the Tevatron repairs, studies of the AP2/Debuncher aperture were performed aimed at centering the beam in the physical aperture and increasing the pbar stacking rate. Analysis of the data continues

A new version of the Run II Upgrade plan, v4, has been issued and baselined in November. The scope and schedule changes in v4 reflect changes to the Run II Upgrade project based on recent accomplishments, operating experience and the rescheduling of the “Fall 2005 Shutdown” which will now occur in the Spring of 2006. The changes were approved at the Run II PMG in early November. The plan and the changes from v3 have been documented.
