CAT Chat Minutes

October 13, 2003

 

Information and Follow-up

User reported problem at the beginning of run - beam orbit had to be repositioned. To correct the problem, User stated it took four hours to get orbit right.

The particular ID beamline involved has very demanding orbit requirements because of a small fixed pinhole. The orbit spec allows for correction to within 1 microradian, and can drift several microradians. Glen Decker has offered to spend time next studies period to make sure that the reference orbit centers the "hot" part of the beam on this aperture.

M. Rivers asked if we could post on the web all PVs that are available.

The BCDA Group and the new webmaster will look into this possibility. At the TWG meeting this week, there will also be a discussion by John Maclean of PV naming conventions.

User would like to see better communication between the management and users on how far along ESAF approval process rests.

Roger informed that Bruce Glagola is in charge of the ESAF process. If ESAF is not submitted to the system within the recommended timeframe, there can be delays. Most Users at todays meeting did not want to have e-mails at every approval stage, and this is not a part of the present system..

User asked at last CAT Chat if the sexual harassment course is something they would have to take in order to work at ANL/APS.

Jeff Alicz spoke with Eve Gohoure about the sexual harassment training requirements. She stated that this course is required for all ANL employees who have a JHQ in the TMS system. However, it is considered optional for individuals who have a JHQ, but are not ANL employees (i.e., APS resident users). Therefore, HR is currently trying to identify those individuals so that they do not receive any type of required training notification for this course. Individuals who do not have a JHQ (off-site contractors, APS visitors, and non-resident users) are also not required to take the training.

Operating Modes R. Klaffky: Roger showed a viewgraph of the operating modes for FY01, FY02, FY03 and FY04, which included number of non-top-up days.

Emergency Access Policy We are currently drafting a policy which will first be reviewed by the task force and AOD.

A viewgraph of the FY04 Long Range Operations Schedule, October2 2003- September 2004 was shown. The summer run period is still in draft status. A SOM request form is being developed and requests will have to be submitted sometime early in November.

Emergency Notification - B. Wesolowski APS will do an e-mail page "test" by the end of the week during the regular workday.

Emergency Power - B. Wesolowski:

This emergency power information will be sent out via cat-net email.

If needed, the EFOG stockroom has cylinders. Let your floor coordinator know what you need and they will see that it is delivered. We realize there is insufficient storage at the present and some CATs are stockpiling cylinders. Some of the cylinders observed are many years old. Overcrowding and unsafe combinations of cylinder in storage could cause a serious hazard risk.

User asked if gas could be stocked in the stockroom. Bill said that APS management preferred that EFOG keep spare nitrogen and helium cylinders to backup the users supplies on an emergency basis (not as a regular supply) and at the present, two cylinders of each. If necessary, he can extend the number he stores to three or four cylinders.
