CAT Chat Minutes

Information and Follow-up Items

What is the standard response time for PFS cleanup? Sector 20 had a water leak occur during the weekend that took just over 2.5 hours for cleanup. First, the water needed to be surveyed by Health Physics and finally PFS was called for cleanup. What is a reasonable responsible time for cleanup?

Bill Wesolowski has contacted the Custodial Manager. In addition, in an emergency, the floor coordinators have access to a wet vac should custodian be delayed.


User Operations

Operation Stats: Delivered beam is 125.55 hours. Percentage of scheduled time is 99.6% with downtime during this period of 0.52 hours. Mean fill duration in period is 41.85 hours; mean time between faults (MTBF) is 62.77 hours. There were three occurrences: 10/9 8:00 a.m. to 9:43 p.m. with duration of 1.73due to turning off pinger; 10/9 beginning 9:58 to 10/10 6:49 a.m., interval 20.85, due to Sector 34 BPLD trip; and finally 10/10 7:06 to 10/14 14:04 of 102.97 duration with fill ongoing.

The Future Operating Modes Workshop, planned for November 6th will discuss the desirability of different machine parameters. An announcement will be sent on CAT-Net following the TWG meeting on October 17th.

Centralized Management of Beamline Scheduling and Utilization: Roger Klaffky presented viewgraphs that displayed a list of task force members; Objective & Timetable for Beamline Scheduling and Utilization; BES FY 2003 Supplemental Reporting Requirements Summary Table of Beam Line Usage; view of scanner and checkpoint stations; APS User Locator Card sample; Beamline Usage Table and calculations therein; and finally On-Line Beamline Downtime Entry Program.

Yeldez Amer extends her thanks to those who cooperated in relaying scheduling information to her. This information will be combined with that of the floor coordinators to derive weekly utilization reports that are to be discussed with each CAT. Work will begin on the spreadsheet template that is expected to be employed in the reporting process by CATs. We will continue to use the paper schedules until uploads from a standard template are in place.

Regarding the BES reporting requirements, a question was raised as to why BES wants to see a report on the beamline utilization. Kevin Beyer, APS floor coordinator, explained that he has posted magnetic tags at every station so that a systematic numbering sequence would be in place. The floor coordinators will scan stations if attended and move along, if unattended with no card, a note will be left for the User to contact floor coordinator upon return to the beamline.

There was discussion about the contents of the User Locator Card and a request was made to modify the cards to show new categories such as time and date.

A user asked if they could fill the locator card ahead of time and was answered that they could.

Other Discussion: Dixie Franklin, CARS, asked for a target date for the new screen so she may check on general user GERT training and other essential training as well as indices status for users. Marcia Wood replied, via e-mail, that an initial version of the form that includes badge number, core training course and link to the users training history would be sent to CAT Administrators on Tuesday, October 15th. Plans for linking the 593 data and resident/non-resident user information are currently being developed.
