Current CNM User Facility Access


On February 25, 2022, the U.S. Centers for Disease Control and Prevention (CDC) issued new COVID-19 safety recommendations centered on COVID-19 Community Levels, which assess the risk the coronavirus poses using county-level data. Argonne has worked with the Department of Energy Argonne Site Office to update our COVID-19 safety plan accordingly, outlining protocols for the low, medium, and high Community Levels.

Effective June 27, 2022, due to a change in transmission levels from Medium (Yellow) to High (Orange) for DuPage County, as per the U.S. Centers for Disease Control and Prevention, our COVID-19 safety requirements have been revised.

  • Face coverings are required, regardless of vaccination status.
  • Social distancing of at least six feet is required, regardless of vaccination status.
  • The wearable proximity device program will resume. If you need a device, contact CNM Environment, Safety and Health Representative Jim Young at jjyoung@​anl.​gov

COVID-19 controls that remain in place include:

  • Site-access requirements for users of the CNM remain in place: users must provide proof of vaccination or negative results from a COVID-19 test conducted within 72 hours of site access.
  • Users should not come to Argonne or CNM if they are not feeling well or exhibit symptoms consistent with COVID-19, regardless of vaccination status. If users become ill while at Argonne, they should stay away from others and immediately call the COVID-19 Question Line at 630-252-2555 for guidance on isolation and restriction requirements.
  • The lab will sustain augmented flow and filtration for building ventilation, enhanced surface cleaning and disinfection, and its contact tracing program.

Beginning on February 28, 2022, the cap for on-site access for users was removed. Only users who have an approved UWA, and who have signed up via the CNM Visit Management System (VMS) (external VMS link and internal VMS link) are allowed on site. Mail-in and remote experiments will remain available.

Please contact the CNM User Office at cnm_​useroffice@​anl.​gov if you have questions about how to apply this updated approach to COVID-19 safety while at Argonne.


Some amenities are now open. The Argonne cafeteria (Bldg. 213) and the 401 Grille at the Advanced Photon Source are serving food. The Argonne Guest House is also open. 


All CNM users are only able to enter the laboratory site if they: 

  • Provide proof of COVID-19 vaccination; or 
  • Provide a negative result from a COVID-19 test conducted within the last 72 hours. 

Users who have been vaccinated against COVID-19 may provide proof in two ways: 

  1. At least two business days in advance of arrival at Argonne, upload proof of vaccination to this folder in Box Plus, Argonne’s secure storage system. Argonne will review the proof and authorize site access if the documents are valid. User badge will be used for access to the site. 
  2. Upon arrival at Argonne, show proof of vaccination at the Argonne Information Center. Proof may only be shown at the AIC during regular business hours (6:30 a.m. - 5:00 p.m., Monday through Friday). A gate pass will be issued for the day while our systems are updated; starting the following day, the user will use their badge for site access. 

Proof of vaccination is defined as a physical vaccination card, photocopy of a vaccination card, or digital image. The time at which the proof is provided must be at least 14 days after the date of the final vaccination shot. Argonne will accept vaccines approved by the World Health Organization: Astra Zeneca, Covaxin (Bharat Biotech), Covishield (Oxford/AstraZeneca), Johnson & Johnson (Janssen), Moderna, Pfizer-BioNTech, Sinopharm BBIBP, and Sinovac. 

Argonne will accept printed COVID-19 test results from either a polymerase chain reaction (PCR) test or a rapid antigen test performed by a healthcare provider no more than 72 hours prior to site entry. Results from at-home testing kits will not be accepted.

Argonne does not require booster shots for any COVID-19 vaccines at this time. 


Principal Investigators (PIs) are notified when work is completed using remote operations, or as newer UWAs are activated or identified. Accepted proposals that have not yet begun, as evidenced by a UWA start date, are being kept in a pending status. 

Currently, the CNM user program is supporting: 

  • Mail-in/remote operation/participation for many capabilities. Tools available remotely are indicated by an asterisk in the list of capabilities at this link.
  • Remote access to the supercomputing cluster, Carbon, and programs developed by CNM’s Theory and Modeling Group.
  • Mail-out programs for select samples, depositions, fabrications, and other select capabilities
  • Visit registration must be booked before arriving at the CNM to conduct experiments. Time can be reserved either through (a) the user’s proposal dashboard if you are not an Argonne employee or (b) the Visit Management System for users who are Argonne employees. An existing or pending user work approval (UWA) on an allocated proposal is required. For the safety of everyone at the CNM, there will be repercussions if we determine you are in a CNM facility without a visit request. For the first occurrence there will be a loss of one month of access, for the second occurrence there will be a loss of two months and a third occurrence will result in loss for the duration of the user work approval (UWA). 
  • Off-hours access for authorized users who are Argonne employees and who do not hold a student status (graduate, undergraduate or high school).

Argonne National Laboratory seeks solutions to pressing national problems in science and technology. The nation’s first national laboratory, Argonne conducts leading-edge basic and applied scientific research in virtually every scientific discipline. Argonne researchers work closely with researchers from hundreds of companies, universities, and federal, state and municipal agencies to help them solve their specific problems, advance America’s scientific leadership and prepare the nation for a better future. With employees from more than 60 nations, Argonne is managed by UChicago Argonne, LLC for the U.S. Department of Energy’s Office of Science.

The U.S. Department of Energy’s Office of Science is the single largest supporter of basic research in the physical sciences in the United States and is working to address some of the most pressing challenges of our time. For more information, visit https://​ener​gy​.gov/​s​c​ience.
