Scope Review: Stacktail Betatron Cooling of pbars in the Accumulator

Goal:

Scope Decision and Technical Review: (WBS 1.3.3.3.2.1.2)

Decide whether to proceed with the betatron cooling upgrade and if so, perform design and technical review before major purchases

Charge:

The goal for the review is to  decide whether to proceed with the stacktail 
betatron cooling upgrade (WBS 1.3.3.3.2.1.2 of the Run II Upgrade Plan) 
in the accumulator or not.

The document (pbar Note 686) outlines the calculations and a few specific
scenarios for stacktail betatron cooling of pbars in the accumulator and 
concludes that the scenario that provides the best improvement of 15% in
transverse emittance is considerably more expensive and more difficult
to build than was originally proposed. The implication of this conclusion 
is that we will not proceed with the betatron cooling subproject.
 
The reviewers are asked to comment on the document and its conclusion and 
provide guidance on whether or not to proceed with the betatron cooling 
system.  

A report from the committee is requested by November 24, 2003.
