CAT Chat Minutes

October 23, 2006

Operations Update, Mark Beno

The run has gone well thus far. New procedures will be put into place to make the clean up easier for the beryllium window breaks that took place. Bruce Glagola will report when these procedures are finalized. Although today was studies day there was beamtime because of station authorization.

Problems during the past week:

  • Cryostat problems
  • Chain hit a window
  • Shutters not opening properly because of air pressure at 21-ID
  • The north station door is falling off at 30-ID


  • 97.7% schedule time
  • Meantime between faults = 100 hours

Safety, Edmund Chang

The EQO pressure assessment is over. The report should be here in a week and we have 10 days to respond.

APS Electrical Inventory, Jim Lang

There will be an inspection of all non-NRTL electrical equipment. This is the beginning of a 4-year plan. The inventory will be our best effort and a fair snapshot of what we have today. A kick off meeting will be held tomorrow at 2:00 p.m. in A1100 (Tuesday) to further explain the inventory to the Safety Representatives. Lang will have a supply of red dot stickers that will be placed on each item as it is inventoried. A safety notice on this subject will be going out soon. This inventory is due to the Lab by December 15 th . Lang is asking that he receive all beamline inventories by December 9th.

XRAY OPS, John Quintana

John Quintana presented material regarding a moderated email list server that has been set up to facilitate communication around the APS (experiment hall and machine) when beamline scientists suspect that there may be issues with storage ring operations that the operations staff may not be aware of. This list is called xrayops and is available from the APS mailman web site:

The APS status and event notification lists are also available from this page.
