November 5, 201512 GeV Upgrade
The conventional facilities scope for the 12 GeV CEBAF Upgrade is complete. Commissioning of the tunnel air conditioning was performed the week of Oct. 12. During commissioning, a control programming issue with the chilled water temperature in relationship to the dew point was identified. The controls subcontractor has corrected the controls programming and the system is working as designed. -

July 15, 201512 GeV Upgrade
Work on the tunnel air conditioning systems is progressing well. A team of insulators have been working inside the tunnel while controls and electrical work is occurring above the ground. Over at the Central Helium Liquefier cold box, fit-up and welding of components is on-track. In the experimental halls, there are several activities in progress, including cryogenics and electrical connections for the Torus magnet in Hall B as well as low-current testing of the Horizontal Bend magnet in Hall C. -

July 1, 201512 GeV Upgrade
One of the last civil construction tasks for the 12 GeV CEBAF Upgrade is the accelerator tunnel air conditioning. Under this contract, installation of the chilled water piping in the tunnel is now complete. Pressure testing of piping segments has begun. With successful pressure tests, the chilled water piping is insulated. Installation of fire sprinkler pipe in the tunnel arcs continues.
