Manuel Lara (left) and Daniel Bennett, postgraduate students at Indiana University, assemble components for what will be called the Forward Calorimeter, a piece of detector equipment being installed in Hall D of the Continuous Electron Beam Accelerator Facility.

Here's a close-up look at a cut-through of a superconducting cable that will be used in Jefferson Lab's Hall B. The cable, which is for the CLAS12 magnet, is soldered to a copper stabilizer. The greenish-looking parts are the braided superconductor wires soldered into the copper channel. CLAS12 is the detector system being installed in Hall B as part of the 12 GeV Upgrade.

John Leckey, a postgraduate student at Indiana University, examines the Forward Calorimeter under assembly in Hall D. When complete, the detector system will contain 2,800 lead glass blocks. Each block will be attached to a photomultiplier tube.  Photons will enter Hall D and interact in the target, producing different types of particles. Some of these particles will hit the lead-glass detector and be converted to light that is measured.

Jefferson Lab staff Technician Thomas Prosper cuts aluminized mylar used for insulation in cryomodules built by Jefferson Lab's SRF Institute. The cryomodule under construction in the background is a C100, one of 10 built and designed to help double the energy of the lab's particle accelerator to 12 GeV, 12 billion electron volts.

As Jefferson Lab prepares for new experiments as part of the 12 GeV Upgrade, crews are demolishing structures and dismantling equipment that were used during the 6 GeV era. In Experimental Hall C, crews are shown demolishing a shield house, which was used to protect a spectrometer. Once all the demolition work is completed, crews will begin installing new equipment for new experiments.
