Wei  Discuss the closeout of DOE  Review

The SNS ring in storage mode (1 sec) for lower intensities were discussed, RF hardware is compatible for this

mode if the intensity is "LOW ENOUGH". Control group should be told for use of this mode.

In the production mode , changing painting function for 1 pulse were discussed, hardware is compatible

for this operation, but YY Lee warn that the next pulse will not be same.

Fedotov updated the instabilities in the ring due to transverse impedance and effect of space-charge

Davino discuss reducing the impedance by changing the height of the 1st seven extraction kickers.
