Obtaining Entry to CNMS Facilities

Photo Identification  - Effective March 30, 2015, ORNL has become fully compliant with the REAL ID Act of 2005. This Act requires that anyone accessing a Federal Facility, which ORNL is, must present a compliant form of identification. State-issued driver's licenses that are not REAL ID compliant will no longer be accepted as proof of identity at ORNL. If you are from one of the noncompliant states, you will need to provide another form of approved identification as listed at You will not be allowed entry to any ORNL facility unless you have a form of compliant identification.

In order to enter the CNMS and/or use computer resources, users must have an approved Personnel Access Systems request issued by Oak Ridge National Laboratory (ORNL). To apply for on-site and/or computer resources, please send an e-mail to requesting an invitation to ORNL. You will receive by return e-mail a link to our Personnel Access System to initiate the registration process. Please include in the subject line of the e-mail 'ORNL Invitation for (your last name).' In the text of your e-mail, include the following:

  1. Project Number
  2. Title of the CNMS Proposal
  3. Name of the Principal Investigator
  4. Indicate Cyber Only (if applicable) - when only computer resources are needed

Note that only individuals who are named as Principal Investigator or Collaborator on an approved CNMS Research Proposal are eligible to apply as a CNMS User. (See instructions below if you need to add a collaborator to a project.)

Non-US Citizens: Please note that access to ORNL facilities for all non-U.S. citizens requires additional processing time for approvals.

Important Information for Users Arriving from Outside the U.S..
In order to participate in research at the CNMS, users traveling from outside the U.S. must enter the U.S. in either Visa Waiver – Business (VWB) or B-1 status. This status must be annotated on the Form I-94 that you will receive from the immigration officer at the port of entry, usually the airport. Before leaving the immigration station, it is important that you carefully inspect the I-94 and ensure that it says VWB or B-1. If it says anything else, you must explain to the immigration officer that you are entering the U.S. for business and require an I-94 that reflects a business visit.

Adding a Collaborator to a CNMS User Project
The Principal Investigator may request an additional collaborator be added to a user project by sending an e-mail to Include the name and e-mail address of the new collaborator as well as the CNMS project number in text.
