Scheduled Maintenance Periods

Three CNM preventive maintenance periods will be in effect in 2013. During these times, the CNM will not be available for user activities in laboratories or on the High-Performance Computing Cluster. Please plan your work visits and schedules accordingly.

To better ensure reliable instrument availability at CNM, defined maintenance periods occur three times per calendar year. These periods are used to perform preventive maintenance on the scientific instruments and their support equipment. The facility's operating infrastructure systems also undergo preventive maintenance that will help avoid unplanned shutdowns. The maintenance periods will occur at these times and are inclusive of weekends:

• January 2-6, 2013
• May 13-19, 2013
• September 3-8, 2013

Additional Holiday Shutdown

Argonne National Laboratory, including the Center for Nanoscale Materials, will close for the holidays at COB on December 21, 2012, and will reopen on January 2, 2013. Neither the CNM building nor CNM staff (including administrative support) will be available to users during the holiday shutdown. Note that this is immediately followed by the January 2-6, 2013, maintenance period shutdown.
