12 GeV Upgrade
A Note on Safety
In Hall B, an important milestone was achieved last week with the completion of the CLAS decommissioning effort. The removal of the north clam shell as the last remaining major structure was completed Friday. With this, Hall B is ready for modification of the forward carriage and of the space frame. The modifications are needed for the installation of the new CLAS12 detector systems and magnets.
2012 Thesis Prize Nomination Deadline Nears
Continued good progress has been made toward making the Virginia funds available for the buncher and cryomodule. George Neil attended the Department of Energy Workshop on Laser Technology for Accelerators.
The mechanical Vacuum and Installation group has been working on many tasks in support of the Long Shutdown. The following is a short list of work that has been completed or is in progress.
Installation has either completed or almost completed the work on:
Installation has also begun the dipole and girder work in the west spreader and work on the low conductivity water system in the east recombiner and east spreader.
Additionally, the Vacuum and Installation group has provided support for cryogenic maintenance, penetration maintenance, power supply LCW repairs, FEL maintenance and 6 GeV accelerator maintenance. The majority of the shunt resistor plates are mounted. Termination for the revised 20-amp quadrupoles are progressing on time. One final note from mechanical is that four of the eight new ZA septum magnets that will be installed in the spreader/recombiner regions are onsite. One of the ZA's has been installed in the southeast recombiner. A second ZA is currently undergoing testing and magnetic measuring.
