Advance registration is required to attend this User Meeting, because of access control at Oak Ridge National Laboratory, a U.S. Department of Energy facility. Registration will open February 20 and end on May 10. On-site registration will NOT be available. All attendees are required to register and provide their name, affiliation, and contact information. Those without an ORNL badge will receive an ‘Invitation to ORNL’ to submit their personal information for obtaining a Visitor Badge. Access to ORNL is for the purpose of attending this User Meeting ONLY, and does not enable access to other ORNL facilities or laboratories. Access to ORNL requires photo identification; foreign nationals will need to bring their valid passport and visa.
