12 GeV Upgrade

Contracts have been awarded for the dipole magnet and the second and third quadrupole magnets for the Super High Momentum Spectrometer for Hall C. All three magnets are of the "warm iron" type; separate contracts for the associated steel yokes will be placed in fiscal year 2012. The second coil for the horizontal bend dipole magnet at the front of the SHMS has been wound at Michigan State University. The first thousand meters of the copper stabilizer that is soldered to the superconducting cable has been extruded, with the balance to follow soon, and the contract for the soldering step is now awarded. Assembly of the first two of five cryogenic control reservoirs for the SHMS magnets is nearing completion at the vendor.

Accelerator

The accelerator has been running well with low trip rates. Both Hall A and Hall B are happy with their beam. On Thursday, there was a beam strike event upstream of the target chamber in Hall C. The event caused the vacuum in Hall C to deteriorate and caused some downtime in the hall. The damaged portion of the beamline was replaced. Hall C started to take beam on Dec. 19.

Free-Electron Laser

The machine lased well in the ultraviolet this week, allowing the FEL team to continue characterizing the vacuum ultraviolet third harmonic output.

Theoretical and Computational Physics

New evidence from lattice QCD is presented <arXiv:1012.3812> for the existence of a bound H-dibaryon, an isospin 0, total spin 0, strangeness -2 state with valence quark structure uuddss, at a pion mass of mπ ~ 389 MeV.  Using the results of the lattice QCD calculations, one finds an H-dibaryon bound by B = 16.6 ± 2.1 ± 4.6 MeV at this pion mass.

Engineering

Engineering Division Professional Development Program
The JLab Engineering Division's Professional Development Program is a series of free seminars to be presented by JLab staff and invited guest speakers representing cutting-edge fields in engineering.

The first set of eight seminars will be devoted to Cryogenics and presented by the lab's award-winning staff, Jan. 25-April 26. Two overview sessions are open to all lab staff, representatives from local industry and graduate engineering students who have a professional interest in the topic; overview sessions will be held at Jefferson Lab in the CEBAF Center auditorium. Six technical presentations are for engineers, senior/mid-level technicians and graduate engineering students; technical sessions will be held in CEBAF Center, Room F113. Eight Continuing Education Units will be granted by the Virginia State Licensing Board to professional engineers who complete the cryogenics series. Space is limited and advanced reservations are required for all sessions.

Facilities Management and Logistics

Holiday Shutdown Power Outage Reminder
A power outage is planned for the area outside the Accelerator Site fence, from 5 p.m. on Thursday, Dec. 23, through 6 p.m. on Sunday, Jan. 2. CEBAF Center, the EEL, Test Lab, and Buildings 52 and 59 will be closed for the outage. The ARC and VARC will not be affected. There will be no power and no access to these buildings during this period. See the full announcement for more details about the outage and other activities. If you have any immediate questions, contact Rusty Sprouse in FM&L, x7589.

Reminder: Personal Space Heaters Not Allowed in JLab Work Areas
Personal comfort and convenience appliances, including portable heaters, refrigerators, fans, coffee makers, microwave ovens, etc. are prohibited from use by individuals. Collectively, these devices contribute to significant energy consumption, fire safety concern, and potential adverse impact on the effectiveness of the automatic building temperature control systems. Electric portable heaters are prohibited except when the installed building heating system cannot maintain the occupied heating temperature range. In this case, FM&L will supply temporary, supplemental space heaters that are properly sized, UL-rated, equipped with safety shut off, and not to exceed 1,500 watts for electrical protection.

Computing and Networking Infrastructure

Holidays Trigger Phishing, Spams and Scams
Be wary of holiday e-mail scams, spams and cyber attacks. The holiday season triggers a deluge of e-mail phishing attempts, electronic greeting card scams and unsolicited spam. Fraudsters see the season of good will as a means to get into your wallet, compromise files on your computer and gain access to the your computer's network. So throughout the holiday season, be sure to follow the same guidance that keeps your computer safe the rest of the year. Be suspicious of unexpected e-mails. Remember that JLab IT personnel will never request your login information or password in an e-mail. If you receive an e-mail that you believe is actually from your bank, a respected e-card site or another known entity, never click the link in the e-mail; instead, type the correct link directly into your browser or use a bookmark to visit the site. As always, if you receive a suspicious e-mail, delete it immediately. If you respond to or click a link in an e-mail on your JLab computer that you think may have been suspicious, immediately change your password and then submit a CCPR to the IT Division HelpDesk or send an e-mail to inform IT that your account may have been compromised. For more information, see the OnTarget newsletter article.

Computer User Audit Coming
The JLab Computer User Audit will begin on Jan. 11. During the upcoming audit, all sponsors of users with JLab accounts will be asked to verify the user is continuing to do JLab-related work. If you have any questions, contact the IT Division Helpdesk, x7155.
