Summary The purpose of this meeting was to report on DOE review.
 

J. Wei summarized the initial feedback from the DOE AP review. There is support for 
the superconducting move in general, but some areas need more study. For example, 
linac beam dynamics, and  more collimation optimization. There was a discussion 
on the PSR instability work. A general sentiment was voiced from the group that 
the R&D money would be more usefully spent doing experimental verification of Ti 
coating the rest of the machine, instead of theoretical model developement. 
K. Reece will pursue this with R. Macek to see if this is feasible. Another
point brought up in the review is the need for a more flexible parameter list, 
and this group needs to play a better integration role. J. Galambos will put 
together a strawman set of working tables on the WWW for discussion at the 
next CC. 

D. Raparia presented some proposed SC cavity parameters to be included in the
working table. He also outlined a strategy for multiparticle tracking studies.
A standard sensitivity study is proposed to understand the impact of individual
error components.

Sang ho's cavity design work was mentioned and it is useful for Sang ho to go 
to LANL next week to discuss this work with J. Billen. It is prefereble for JLab 
to also attend.

S.Y. Lee proposed doing space charge experiments at the IU  synchrotron. The
parameter space needs to be scoped to see how useful these studies would be for 
scaling to SNS parameters, and the cost of the experiments also need to be examined. 
There was also a discussion of scape charge experiments on the AGS booster. K. Reece
proposed bumping the beam into a collimator in the ring and monitoring
the beam loss measurements, to examine the beam profiles. This would be in the ring, 
and avoid extraction difficulties.

D. Jeon discussed syncrcrnous particle tracking studies with errors. Correlated micro-phonic
errors show small (< +- 0.5 MeV) energy jitter, consistent with LANL results.

Action Items
 
a) K. Reece will contact R. Macek about fully Ti coating the PSR. 
b) J. Galambos will set up a strawman set of working tables on the WWW for discussion Tues.
