October 15 Briefs Excerpts: 


Sprinkler System Maintenance in CEBAF Center 
A work crew is currently on site, performing annual maintenance on the CEBAF Center Fire Safety System. Building occupants may notice that building water may appear brown or discolored after 4 p.m. today and after 3 p.m. tomorrow and Friday (Oct. 16-17). There is no cause for alarm, but before using the water, make sure that it runs morning please make sure to run water until clear before using. There is no cause for alarm, but run the faucet until the water is clear before using. If you have any concerns about this work, contact Tim Minga, minga at jlab.org. 


Jefferson Avenue Roadwork 
The construction contractor for the new Tech Center site will begin working on adding the new turn lanes and widening Jefferson Ave. this week as weather permits. This work is scheduled to take place over the next six weeks. Crews will begin working south of Hogan Drive and will proceed north on Jefferson Ave. Use extra caution when approaching the lab on Jefferson Ave. throughout this construction phase, and obey all flagmen and signage. 


CNI Systems Maintenance Period Set for Tuesday, Oct. 21, 5-10 p.m. 
The IT Division CNI group is planning a maintenance period on Tuesday, Oct. 21, 5-10 p.m. During this time, there will be a short (approximately 10 minutes) outage for the Technology and Engineering Development Bldg. (Bldg. 55) 2nd floor while the power is updated to the network switch. There will also be a few short (10-30 second) internet outages for network updates. In addition, there will be several central outages to the central MySQL servers, cnidb and jmysql, which will cause outages to several services. The MIS applications will be down while maintenance is performed on the underlying file servers. The total outage will be no more than 30 minutes. In addition, there will be short outages of several central servers, including jlabl1-4.jlab.org, login.jlab.org, while they are rebooted after patches. The central mail servers for spam and virus checking will be down for about 30 minutes while updates are applied. Outgoing mail may be unavailable during this time, but all incoming mail will be stored on the remote servers and then re-sent when the service comes back up. Updates to Firefox, Thunderbird, Flash, and Java will be released to the site. And, lastly, Linux and Windows patches will be released to all desktops and servers. Plan on rebooting your Linux or Windows desktop by Friday, Oct. 24, to finalize the patch installation. If you have any questions or concerns about this maintenance period, contact the IT Division Helpdesk, x7155. 



Colloquium: The Pursuit of Better SRF Cavities 
Join Charlie Reece as he describes the superconducting niobium rf cavities that provide a remarkably efficient way to accelerate charged particles, especially for continuous wave applications. He’ll explain how practical cost pressures continue to motivate development of ever more energy efficient and lower capital cost systems and discuss the push to realize reliably SRF cavity surfaces with very low surface resistance with maximally high surface fields. He'll also address recent developments, including a collaborative effort involving JLab, Fermilab, Cornell University, and The Helmholtz-Zentrum Berlin for Materials and Energy, as well as the LCLS-II project that will exploit new developments to minimize cryogenic capital and operating costs. These new understandings and associated challenges will be reviewed in their historical international and Jefferson Lab context. The colloquium will be held in the CEBAF Center auditorium on Oct. 22 at 3 p.m. 


Share Your Photo for Veteran’s Day Tribute 
Jefferson Lab will again recognize its veterans on Veterans Day, Nov. 11, with a small display. This year, a photo exhibit of lab veterans in uniform is being prepared to highlight employees’ service. If you are a veteran and would like to participate, email or bring in your military service photo to Mike Robbins, CEBAF Center room C222 or mrobbins at jlab.org, before Oct. 31. These photos can be of any time during your service from boot camp, to a retirement photo, to anywhere in between. Include with your photo your name, branch of service and years of service.

If you would like to participate, you must pre-register your two-person team by COB Monday, Oct. 27 by contacting Mike Zarecky, x7609 or zarecky at jlab.org. If you'd like to play but don't yet have a partner, sign up to be added to a list of potential players. 


Come Out and Enjoy JAG Oktoberfest!
