The U.S. Department of Energy (DOE) National Science Bowl® is a nationwide academic competition that tests students’ knowledge in all areas of science and mathematics. Middle and high school student teams from diverse backgrounds are comprised of four students, one alternate, and a teacher who serves as an advisor and coach. These teams face-off in a fast-paced question-and-answer format, being tested on a range of science disciplines including biology, chemistry, Earth science, physics, energy, and math.

Hall B is the site of the CEBAF Large Acceptance Spectrometer called CLAS12. Powerful magnets steer the electron beam into a target in the experimental hall. The beam's individual electrons smash into the protons and neutrons inside the nuclei of atoms in the target. These violent collisions produce new particles; heavier versions of the familiar protons and neutrons as well a whole variety of intermediate mass particles called "mesons". The outgoing electron that collided with the target nucleus, as well as the produced particles, go flying out into our detector, where they're measured.
Our job as particle physicists is to use these measurements to try to deduce the underlying structure of protons and neutrons in the target and to try to understand the forces that create these particles.

Department of Energy: Actions Needed to Assess U.S. Manufacturing Policy and Protect Technology from Foreign Acquisition
Note: Four of the 17 labs and six of the 19 universities did not provide templates to GAO for review. The labs stated that they do not have their own exclusive templates and instead use a sample agreement for non-exclusive licenses, which was created by DOE's Technology Transfer Working Group. Six universities declined to share their templates. For each of the license template provisions shown above, we reviewed whether the provision was comprehensive, present but not comprehensive, or not present. We use "comprehensive" to mean that the clause is strongly drafted to protect the lab or university from the risks associated with the applicable activity, for example, a change in control. We use "present – not comprehensive" to mean that the clause is drafted in an incomplete way that provides some protection but still leaves the lab or university somewhat exposed to such risks. A template where "no [such] provision [is] found" provides no protection from such risks.

A group of lab scientists, technicians, mechanical designers, engineers, scientific users and students are building a new electron calorimeter in Hall A. Known as ECal, the apparatus is a detector for a nuclear physics experiment that will allow scientists to better understand the internal structure of the proton.
