P5 recommendation on Tevatron running

Report of June 8 meeting

FNAL

Charges

• Should the Tevatron run through the end of FY09 as currently planned?

• What are the factors and considerations which might lead to running beyond FY09?

Run through FY09?

• Will the accelerator deliver interesting level of integrated luminosity?

• Can the detectors handle the luminosity?

• Do the collaborations have the people to operate the detectors and analyze the data?

Subject of June 8 meeting

Running beyond FY09

• What is present reach and prospect for new discoveries? Trigger issues Endgame strategy

• Battling the sqrt N barrier--will a few more fb-1 matter?

Running beyond FY09

• What is present reach and prospect for new discoveries? Trigger issues Endgame strategy

• Battling the sqrt N barrier--will a few more fb-1 matter?

Might know more after analyses for Summer conferences

Meet again in September to consider

Accelerator projections

D0 detector performance

• Basically running well, producing nice results

• Remaining issues for 09: Silicon radiation damage Fiber tracker occupancy

Findings summary

• Accelerator running well and will likely deliver 6-7 fb-1 by end of FY09

• CDF and D0 detectors running well, some issues for 09 but no show-stoppers

• CDF resources matched to needs through FY09

• Concerns about D0 people power in FY09

• Examine case for running beyond 09 at next P5 meeting (likely end of September)

Recommendations summary

• Tevatron should run through end of FY09

• Lab should work with D0 to augment human resources Visitors program is highly leveraged and cost-

effective Additional Applications Physicists?
