CAT Chat Minutes

Information and Follow-up Items

The liquid nitrogen dewars are moved through the truck locks for refilling. In some areas the pavement is cracked and uneven which can cause a safety hazard. Can we get this fixed?

We will examine these areas and repair the surfaces.

Modifications are complete. Access should now be available to view the APS stock catalog.
