CAT Chat Minutes

October 2, 2006

Announcements/Schedule Update, Mark Beno

Beno welcomed participants to the first CAT Chat of Run 2006-3.

Safety, Tom Barkalow

Barkalow clarified the new requirement for helmets for riders of bicycles and motorcycles. This requirement applies to vehicles ridden on Argonne 's roadways, not to tricycles ridden on the experiment hall floor.

Barkalow also announced a new site-wide assessment of pressurized systems to begin on Monday, October 9. APS will be a focus area. Users may be contacted and asked about the design or operation of vacuum systems, but it is more likely that APS staff members will interact with the assessment team.

Safety: ESAFs, Bruce Glagola

Glagola explained the basis of problems with the ESAF system during the past week. The announced server upgrades were coupled with software upgrades. The new version of Oracle was incompatible with several of the functions in the ESAF application. These problems have now been corrected. Users were asked to notify Bruce ( immediately if additional problems occur.

Equipment Pool , Kevin Beyer

Beyer announced that the following items have been added to the equipment pool:

  • Lindberg/Blue Modatherm 1100 degree box furnace
  • Linkhorn THMS600 heating and freezing stage
  • Cryo-cycle LP 120
  • Cole Parmer brushless variable speed digital peristaltic pump drive

Users with requests for additional items to be added to the pool should contact Beyer (

Liquid Nitrogen Problems, Kevin Beyer

Last Thursday, a large draw on liquid nitrogen triggered a low-level alarm. Unfortunately, the alarm was not handled expeditiously, which led to problems on one beamline. The APS is working with that beamline to assess and handle that situation.

During the run, probably after October 17, two new liquid nitrogen tanks will be installed in the Bldg. 432 truck lock. After next week, module A in that area will be allowed to run dry, then isolated from the system and removed. Until the new tanks are installed, the frequency of fill for the remaining B, C, and D modules will be increased.

Argonne Open House, Mark Beno

Beno reminded users that Argonne 's Community Open House will be held on Saturday, October 7, from 9:00 a.m. until 4:00 p.m. More than 20,000 people are expected, which means that parking will be a problem for users and staff. Visitors will not be allowed on the experiment hall floor beyond 1-BM. However, family members and friends of staff members may visit offices in Building 401 and the LOMs if the appropriate staff member accompanies them.
