The detector system will be used by the GlueX physics collaboration.
An overhead view of Hall D, the newest experimental hall at Jefferson Lab, and part of the 12 GeV Upgrade project. On Dec. 14, operators of the Continuous Electron Beam Accelerator Facility (CEBAF) delivered 12 GeV electrons (12.065 Giga electron Volts) to the Hall D complex. Critical to the detector system is the superconducting solenoid magnet – the large red and green equipment is the solenoid.
