JEFFERSON LAB SEARCH

Experimental Hall C

Jefferson Lab has four experimental halls. Hall C is 150 feet in diameter and 60 feet tall.

Hall C houses two large spectrometers, the High Momentum Spectrometer and the new Super High Momentum Spectrometer.  The hall also provides space for temporary installation of other detectors such as the Neutral Particle Spectrometer and the Large Acceptance Detector.

The research equipment in Hall C is used to study form factors and 3-D structure of simple quark systems, and short range structure in nuclei.

Zeroing in on a Fundamental Property of the Proton’s Internal Dynamics

Theory and experiment combine to provide the most precise empirical extraction of the proton’s tensor charge, a fundamental property of the proton.
