JLab Site Information


On Monday, June 7, 2021 Jefferson Lab continued its gradual, phased and coordinated process of returning to on-site operations, in line with Department of Energy and Commonwealth of Virginia recommendations to help limit the spread of the COVID-19 pandemic. In doing so, we are continuing to place the highest priority on mitigating the risk of future COVID-19 outbreaks amongst our workers.

At this time, the majority of the Jefferson Lab workforce will remain in a remote work status continuing to advance the Jefferson Lab mission. A limited number of Jefferson Lab staff, scientific Users and subcontractors are permitted to return on-site to perform mission-essential work that cannot be accomplished from off-site. 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.

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.
