Argonne National Laboratory, including the Center for Nanoscale Materials (CNM), is closed beginning December 23, 2022, at 5:00 pm CST and will reopen on January 3, 2023 at 7:00 am CST. The CNM suspends user operations during this closure; neither the CNM building nor CNM staff, including administrative support, is available to users at any time during the winter break.
The winter break will be followed immediately by a preventive maintenance period for a week to be determined in January 2023. During this period some capabilities may be unavailable at times and the servicing of some infrastructure systems may affect operations. More information will be sent to the user community as the date nears.
