The US Department of Energy’s Thomas Jefferson National Accelerator Facility, or Jefferson Lab, will hold an open house for the public on Saturday, April 30, from 9 a.m. to 3 p.m. It is an opportunity for people of all ages to spend the day exploring this world-class research facility. Visitors will be able to take part in tours, hands-on activities and interactive displays and demonstrations, such as the popular Liquid Nitrogen Show. Guests will also be able to see much of the lab and learn about its research program and technological advances.

Staff and visiting scientists will be on hand to discuss the research underway at the lab, its particle detection and supercomputing capabilities and its particle acceleration capability (superconducting radio frequency), a technology with growing interest in the US and abroad.

A number of local universities, museums and other organizations will also be participating in the event and presenting activities and information on scientific endeavors.

The event will be spread out over several buildings and outdoor areas and involves a lot of walking, taking flights of concrete stairs and walking down and back up rough, inclined truck ramps. In some areas, visitors will walk on compacted gravel or dirt surfaces instead of pavement. Visitors are encouraged to wear sturdy, comfortable shoes and sunscreen or a brimmed hat and protective clothing.

Jefferson Lab is located at 12000 Jefferson Ave., Newport News VA. The event is free of charge and will be held rain or shine. Families, individuals and groups are welcome. Free parking is available. Lots open at 8:30 a.m., but no vehicles will be admitted after 2 p.m. Free shuttle buses will be available to carry visitors between most of the tour stops, and nearly all areas will be accessible by wheelchair. Photos and video recording are welcome.
