## Collider Run IIa Luminosity Goals

- For Run I:
- Typical peak luminosity ~1.6x1031 cm-2 s-1
- Typical weekly Integrated luminosity ~2 pb-1
- Total integrated luminosity delivered ~0.14 fb-1
- The official luminosity goal for Run IIa was defined in the data sheet for the Main Injector Project:
- “The Tevatron proton-antiproton colliding beam luminosity will be increased to at least 5x1031cm-2sec-1.”
- Total integrated luminosity of 2 fb-1
- We are committed to exceed that official goal with additional effort and the Recycler.  The limits are believed to be:
- 8x1031 without the Recycler
- 2x1032 with full benefit of the Recycler

## Operations Issues: Incidents

**Unclean Aborts**
**Correct Kicker Timing, (DC)  beam in abort gap**
**Mitigate by using Tevatron Electron Lens to remove DC Beam from abort gap**
**Incorrect Kicker Timing**
- Trigger Circuit misfiring
- Thyratron misfiring (the most recent)
- Affects (mainly) CDF Silicon

## Progress

**Every** performance improvement evident in the luminosity performance plot has been associated with a specific modification to the accelerator complex.
- Major modifications since January 1, 2002:
- Accumulator->Main Injector transfer optics
- Adjustment of tunes during low beta squeeze
- Modified injection helix in Tevatron
- Proton beam loading compensation in Main Injector
- Accumulator (stochastic) cooling upgrade
- Accumulator shot lattice
- Antiproton beam loading compensation in Main Injector
- Tevatron beam line tuner (BLT)
- Tevatron tune/coupling drift compensation
- Tevatron transverse dampers
- Steve Holmes note: (1.15)10 =4.0

## Help from Others Inside the lab

- We are fielding many offers of help, both from within and from outside the laboratory. Effective integration requires:
- Three-fold match of capabilities, need, and internal contact
- Case-by-case facilitation
- We are effectively integrating resources from within the laboratory, but outside the Beams Division
- PPD: Assistance on instrumentation projects, Recycler vacuum. Transfer of the PPD deputy head and former CDF silicon project manager to BD. Technician support for shutdowns.
- CD: Shot Data Analysis and instrumentation projects. Applications programming support.
- TD: Component fabrication, magnetic field monitoring, time dependent currents, instrumentation projects, Recycler planning. Technician support for shutdowns.
- ~50 people total, 20-25 FTEs

## Help from OthersOutside the Lab

- And outside the laboratory a number of things are happening or are in the works:
- SLAC: Accelerator simulations and instrumentation
- LBNL: Visits aimed at identifying areas of participation
- ANL: Tevatron vacuum and Booster instabilities
- BNL: Personnel visits (Tevatron acceleration and IR issues)
- CERN: Personnel visits
- Exchange of letters formalizing a collaboration and projecting Fermilab participation in LHC commissioning.
- Maryland: accelerator modeling (Recycler)

## DOE Review of Collider Run II

- The overriding impression of the Review Committee is that Fermilab has embraced the challenge of meeting the luminosity goals for the Tevatron complex and that the Laboratory realizes the significant level of challenges ahead.
- There has been excellent progress in the past year that serves as a solid platform for future progress and the increased focus of the Laboratory on this effort is a crucial factor.
- The Committee judges that there is a good likelihood that the “base” luminosity goal set for FY03 will be met or even exceeded.

## A look at the longer future

- Luminosity projections throughout Run II
- We have done detailed studies of technical issues to be addressed.
- Caveats
- R&D is still going on.
- Detailed schedule and resource planning is still needed.
- Funding is not known.

## Run II Physics Program

**Run II Physics Program**

**2fb****-1**** **
- Measure top mass ±3 GeV
- Measure W mass ± 15 MeV
- Directly exclude mH = 115 GeV
- SUSY Higgs search @ large tan 
- Constrain the CKM matrix
**6.5 fb****-1**** **
- 3 Higgs signal @ mH = 115 GeV;
- exclude Higgs 115-125, 155-175 GeV
- exclude much of SUSY Higgs parameter space
- possible discovery of supersymmetry in very large fraction of minimal SUSY parameter space
**11 fb****-1**
- 3 Higgs signal mH = 115-125, 155-175 GeV;
- exclude Higgs over whole range 115-175 GeV
- possible discovery of supersymmetry in larger fraction of parameter space
**15 fb****-1**
- 5 Higgs signal @ mH = 115 GeV;
- 3 Higgs signal 115-175 GeV

- Each factor of  two in luminosity yields a significant increase in reach and lays the foundation for the next steps

## DOE Review: Goals Beyond FY03

- The Laboratory’s technical approach for increasing luminosity over the next six years is sound and well motivated and, if successfully implemented, will maximize the integrated luminosity over this time period.
- The Committee believes that reaching the base luminosity goal ... will be a significant challenge.
- ... adequate funding throughout the luminosity upgrade period is not assured and so constitutes a substantial risk to reaching the goals.
- The DOE should undertake a follow-up review in about 8 months...

## Long Term Tevatron Run Plan

- Run CDF and DØ until the LHC experiments start to produce physics results that dominate our picture.
- Low mass Higgs searches are among the most challenging, even at the LHC.
- Be  prepared to run the Tevatron until 2010
- The luminosity projections require that we upgrade the detectors, starting now.

- Fermilab Physics Advisory Committee

- November 14, 2002

## Run IIb Detector Upgrades

- In June you recommended laboratory approval to CDF and D0 upgrade projects that would
- replace radiation-damaged silicon detectors with new detectors of simpler design with more radiation-hard technology.
- upgrade data acquisition and triggers to deal with higher luminosity.
- We held successful Lehman baseline reviews in September.
- No action items, recommended reduced contingency, which we accepted
- External Independent Review complete, preliminary report looks good.
- Aiming to start project by January

## Summary

**The Luminosity has shown a steady and very significant increase over the course of 2002.**
**There are still many things which are known to be problems so the potential is by no means exhausted.**
**We are projecting a factor 2-3 over the course for FY2003**
**The strategy tries to balance integration of luminosity with providing the Accelerator Complex with space to improve.**
