Issues that require action and/or follow-up
1. We have discovered that the amount of information on the Web for work permits is not enough for us to determine how we will be impacted. What can be done?

We will work on improving the content of the information and will provide follow up through the floor coordinators.

2. The APS would like your opinion on refill criteria. Would the users prefer to refill on a predetermined time schedule or is the existing current-based refill better for taking data.

For the present, the current method is adequate.

3. The rf problem, did it just go away?

A couple of changes were made that could have corrected the problem - one being air cooling into the cabinet, and the other being the replacing of the trigger card for the crowbar.

Information
The storage ring is performing much better. The duration of the fills is averaging ~ 9 hours.
