CAT Chat Minutes

August 15, 2005

 

Information and Follow-up
Liability - Users and staff discussed need to call the floor coordinator and/or emergency response.

John Quintana answered that liability is a legal term and the Institutional User Agreements address such issues.

Still looking for volunteers for automated x-ray beam steering tests. John will talk more about these tests at the 8/18/2005 TWG meeting.

Green Detex Burn Paper is no longer available. Stockroom has run out of the papers and the vendor cannot supply more.  John passed out samples of paper (see specs below) as we continue looking for options.
