Hall D Counting House

Jefferson Lab's Experimental Hall D.


Experimental Hall D

Jefferson Lab’s fourth experimental hall, known as Hall D, began receiving beam for calibration and commissioning purposes late in 2014.

The Hall D complex consists of an extension to the accelerator tunnel to house a transport line for the electron beam, which is used to produce a beam of high-energy photons, the experimental hall and its associated detector systems, a counting house, cryogenics plant and service buildings.

Experiments to be conducted in Hall D will make it possible for scientists to study what are known as exotic or hybrid mesons.
