Goal:

Review the potential benefits of wire-based beam-beam compensation, assess status of studies and make decision on initiating R&D, with the expectation that the R&D would be further reviewed before a decision on a production system is made.

Charge:

Address the potential benefits of a wire-based system for active beam-beam compensation in the Tevatron and assess its role in the context of the Tevatron Electron Lens. Review status and adequacy of the studies carried out so far.

Provide guidance on the following specific issues:

Is wire compensation of beam-beam effects potentially useful for increasing the luminosity?
How should the wire compensation complement the compensation with the Tevatron Electron Lens (TEL)?
Are the right strategies being used for compensation?
Is the engineering scope of the project well understood?
Should we proceed with an R&D project to build the system?

The committee should provide a preliminary assessment at the closeout meeting. A final written report should be produced within a week of the review.
