12 GeV Upgrade

On Feb. 5, 2.2 GeV/pass tune beam was transported to 2R and held there for eight hours. This energy is a new record for one pass and is the machine performance needed to eventually deliver 12 GeV beam to Hall D and 11 GeV beam to Halls A, B and C. This demonstrates one of the Key Performance Parameters needed for CD-4A approval of the 12 GeV CEBAF Upgrade project. Starting from pre-calculated settings for the magnets, only minor adjustments were needed for the steering and optics. Beam transport installations for the accelerator are complete. The beamlines to the halls are being completed with vacuum checkout. The rebuilt YB septas in the east spreader/recombiner have been set back in place and are being hooked up and aligned. All radiofrequency and cryomodule scope has been completed. Box supplies for arcs 3-6 are onsite and at various stages of checkout. MARC5 and MARC6 are ready for testing with the dipole magnets. The final shipment of the 20 Amp trim supplies is on the way from the vendor. The Personnel Protection System installations for the 5.5 pass recirculation are complete. The order for the stripline beam position monitors has been awarded. Work is starting on the nano-Amp beam position monitors for Hall D.

Environment, Safety, Health and Quality

Proper Gloves
Just like hard hats and safety glasses, gloves are a key component of a worker's safety gear in the industrial sector. However, the critical protection offered by gloves becomes meaningless when workers refuse to wear them because they are uncomfortable or too cumbersome. Every year, approximately 1 million workers in the United States are treated in emergency rooms for acute hand injuries incurred on the job. According to the Bureau of Labor Statistics, 70 percent of workers who experienced hand injuries were not wearing gloves, and the remaining 30 percent experienced injuries due to wearing damaged gloves or the improper type of glove for the application.

At Jefferson Lab, there are a wide variety of gloves available in the Stock Room that have been selected for the type of hazards at the lab. As one can imagine, there is no one glove for all hazards, so the supervisor in consultation with Industrial Hygiene has selected the type of glove for a particular job. The type of glove is specified in the various work control documents for that work. "Rubber" gloves, a poorly used generic name, is applied to numerous types of soft, pliable-material gloves, but each has distinct chemical resistance properties. Therefore, it is important to use only the glove specified, and in the correct size and in good condition, for a particular chemical so that you avoid a skin injury. For more information regarding glove selection, consult the ES&H Manual.

Computing and Networking Infrastructure

CNI Maintenance Period Tuesday, Feb. 18, 5-10 p.m.
The IT Division's CNI group will hold a systems and network maintenance period on Tuesday, Feb. 18, 5-10 p.m. During this time, work will be performed on the Zimbra mail system, which may cause some interruptions to service as the proxy servers are upgraded. Updated certificates will be installed on www.jlab.org, so there may be a brief outage while the certificate is installed and the system is rebooted. Also, there will be an update to the Cisco IP phones that may cause the screen to flash, but no active calls will be affected. A Firefox and Thunderbird update will be released to all Windows systems, as well as a flash plugin update. All MIS applications will be down while patches are applied to the backend servers and rebooted. Finally, patches will be released to all Windows and Linux systems. Plan on rebooting your system on the Thursday or Friday following CNI Maintenance. As always, if you have any questions or concerns, contact the IT Division Helpdesk, x7155.

Computer User Audit Begins Next Week
The annual Computer User Account Audit will begin on Monday, Feb. 17. All supervisors and sponsors of users with computer accounts at Jefferson Lab are required to review and re-authorize these accounts. This audit is a critical part of maintaining an appropriate level of cyber security at Jefferson Lab. If you sponsor someone with a computer user account at Jefferson Lab, you will receive an email on Feb. 17 with information on how to complete your user audit. If you have any questions or concerns regarding this audit, contact Jessica A. Perry, x7262.
