CAT Chat Minutes

July 31, 2006

Operations Update, Mark Beno

Beno told the group that there were two drops during the week, lasting just one hour each. We were at 98% availability, and there were 64 hours between faults.

Beno also reported that XSD will have its own safety person on board by August 14 th .

Safety, Tom Barkalow

Barkalow reported that the Building 437 construction has been completed. The gates have been removed and the roads are open once again. Prior to the gates being removed, there was an incident involving a bike rider who ignored the fact that there was a crane being used and rode directly through the lift zone of the crane. Barkalow reminded all to be aware and heed all warning signs and warning tape.

Barkalow cautioned the group to be aware of the increased bee and wasp sightings on site. He reminded all to be cautious especially near the gas cylinder storage areas where they have started to build their nests.

Barkalow also reported an incident at IPNS where a stack of concrete blocks collapsed. Fortunately, there was no one in the area. Apparently, the blocks had been stored on wooden crating, and the crating had given away under the extreme weight of the concrete.

Results of Cyber Security Audit, Ken Sidorwicz

Sidorwicz gave a follow up on the Cyber Security Audit that was conducted recently. Apparently, ANL came through the audit very well, and the audit team was impressed.

Because of the credit union scam that had begun prior to the audit team's arrival, they did not do any social engineering this time, but may be doing this through e-mail communications in the future.

ACS Motor Controller Problems, Ron Sluiter

Sluiter reported on the motor control failure on Tuesday, July 25 th , at the sector 34-ID wide beam hutch. Because of this failure, three days of beam time were lost. This type of problem had never been reported before. The situation is being investigated by Sluiter and the Beamtline Controls Group.
