JLab Site Information

On Monday, June 8, Jefferson Lab began a gradual, phased, and coordinated process of returning to on-site operations. In doing so, we are continuing to place the highest priority on mitigating the risk of future COVID-19 outbreaks amongst our workers.

A limited number of Jefferson Lab staff and scientific Users will be allowed to return on-site during this time to perform mission-essential work that can not be accomplished from off-site. On-site workers will be required to practice social distancing, wear cloth face coverings in public areas, wear full PPE when social distancing is not possible to perform a vital job, and follow other Centers for Disease Control and Prevention and U.S. Department of Energy guidance.

The priorities for on-site work include resumption of the CEBAF experimental program, as well as continuing to deliver on other projects deemed essential to the lab’s mission. We anticipate that most of our staff members and scientific Users will continue to work off-site at this time, continuing to advance the Jefferson Lab mission while maintaining social distancing. The lab will keep monitoring and adapting to changing conditions on-site, in our surrounding communities and state, and nationwide.


Jefferson Lab's geographical location in Newport News, VA, makes it susceptible to a variety of severe weather events with the potential to damage property, adversely affect Lab operations and cause personal injury.

The National Weather Service provides near-term forecasts for these weather events with sufficient advance notice for site preparations and decisions about lab closings. Less predictable weather events, such as lightning and tornados, usually occur under specific conditions, and these precursor conditions are typically forecasted in advance. Heeding these advance notices, and using them to prompt Jefferson Lab weather preparations, is essential to reducing weather-related risk to equipment and people. At Jefferson Lab, personal safety takes precedence over other considerations.
