Well be contacting the other CATs because we need to know the specific needs/requirement of each CAT, such as protocols for certain computers, etc. If you havent been contacted and you wish to address this issue immediately, you can contact M.

User Operations

The machine has been running well at 90%. Earlier this week we had several problems, primarily with power supplies and rf trips.

The User run will continue through 0800 on Tuesday, December 8. An eight-hour period for Machine Studies will follow; thereafter the Special Operating Mode (SOM) will follow at 1600 with singlets through the end of the run until 0800 on December 14, 1998. During the singlets operation, storage ring refills will occur twice per day, at 0800 and 2000.

Top-up mode studies The vertical beam feedback interaction with top-up has been corrected. We will work out a schedule shortly for upcoming studies periods during the January/February run.
