The NCNR now uses the web-based Information Management System (IMS) to track interactions with its facility users.

The following steps must be followed before a first time user can obtain unescorted access to the NIST site and unescorted access to the experimental areas of the NIST Center for Neutron Research (NCNR). These procedures are designed to meet NCNR security and safety requirements.

If you have any questions please contact the NCNR User Office (K07) at 301-975-8200 or email
