12 GeV Upgrade

Accelerator Readiness Review
Preparations are underway for an Accelerator Readiness Review. The purpose of the review is to ensure that the new facility is poised to safely commission and operate. This process starts with the development of a Safety Assessment Document. JLab is updating Revision 7 of the Final Safety Assessment Document (FSAD), which will incorporate changes to the facility resulting from the 12 GeV Upgrade project. Development of this draft document is on track to be released for review by the end of August.


Current Hall A efforts are focused largely on 11 GeV beamline preparation. The Moller polarimeter quadrupole arrival is imminent, and power and controls are being readied for it. A solution to map the Compton polarimeter magnets in place has been determined and should begin soon, as the Compton magnet field plate extensions are finalizing.

Long Shutdown

The CEBAF cryomodules are by now essentially warm, and systematic maintenance has started in the North Linac. The R100 cryomodule, in design and performance almost the same as a C100 and the most critical element for the injector energy upgrade, has been moved to its final location, and it is ready for alignment and installation. With the spreader and recombiner areas essentially cleared out, the de-installation activities in the tunnel turned to the recombiner in the beam switchyard area. Several refurbished Arc 3 dipoles have been returned to their locations in the east arc. The re-survey of the accelerator control network in the west arc has been completed, and the focus turned this week to the east arc. The de-installation work continues in Halls A, B and C. The contractor for the installation of the new Central Helium Liquefier-1 cooling towers is on site for mobilization and preparation, with the work to start soon.

Free-Electron Laser

The linac is warming up, and staffers have made good progress in developing a resource-loaded schedule for the rest of the calendar year. The FEL team is also starting to map out the details of the run schedule for the first half of next year, which will include the enhanced energy-recovery scheme and the plan for a new injector booster.


The machine shop has set up and made operational the magnet re-manufacturing area. To date, the shop has re-manufactured 30 magnets for reassembly. Hall B's CLAS12 High Threshold Cerenkov Counter mold mirror facet blocks 2 and 3 are being cut to size. The 170 accelerator dipole-lengthening shims for 12 GeV are being final machined to coincide with the modification of the cores, and 30 strip line beam position monitors are in the process of being welded. The shop has processed 173 job requests since June 25.

Environment, Safety, Health and Quality

Trikes are Back – Be Alert
You may have seen the new tricycles around JLab and wondered about them. Four of the tricycles are assigned to the Technology and Engineering Development building occupants and two are assigned to Facilities Management and Logistics. These tricycles have baskets, so any time you need to transport items around the JLab campus, you can sign out a tricycle for this use. As always, take the time to familiarize yourself with the vehicle, and do not take it onto JLab streets until you are confident that you can operate it safely. As a reminder, always exercise caution when traveling on JLab streets and be especially mindful of pedestrians, bicycles, golf carts, motorcycles and tricycles.

Computing and Networking Infrastructure

Network Maintenance Set for Saturday
The CNI Networking group is planning a network maintenance period to update a key network router. Internet access from most internal JLab addresses will be down on Saturday, Aug. 18, 9-10 a.m. All internet access will be restored by 10 a.m. If you have any questions or concerns, contact the IT Division Helpdesk, x7155.

CNI Systems Maintenance Scheduled for Aug. 21, 5-7 p.m.
The CNI group is planning a maintenance period on Tuesday, Aug. 21, 5-7 p.m. During this period, the non-Zimbra email system and the lqcdweb server will be offline for about 30 minutes. The web server will also be offline for about 45 minutes in order to update and improve the system.

Additionally, Windows and Linux security patches will be pushed out to all desktop systems. Plan on rebooting your desktop system when you have the opportunity in the day or two following this maintenance period. If you have any questions or concerns, contact the IT Division Helpdesk, x7155.

Zimbra Calendar Testing
The CNI group is planning to open the Zimbra calendar to the site for testing starting on Monday, Aug. 20. During the test phase, all entries in the calendar will be considered "test entries" and will be deleted prior to the actual cutover during the weekend of Sept. 1. During the cutover, all meetings from Jan. 1, 2011 through Dec. 31, 2014 will be migrated from the Oracle calendar into Zimbra. To access the new Zimbra calendar, once it has been opened for testing, just bring up the Zimbra web interface, log in, and click on the Calendar tab. Some frequently asked questions and answers to help you get started are documented online. Frequent calendar users are encouraged to take advantage of the calendar testing period to generate any questions they want answered in the Zimbra training seminar (next brief).

Zimbra Training Offered in August
To smooth the transition to the new system, the CNI group will be offering training seminars on the use of the Zimbra calendar and email system on Monday, Aug. 27 and Tuesday, Aug. 28 in the CEBAF Center auditorium. Two sessions will be offered each day: 9:30-11 a.m. and 2-3:30 p.m.

Operational Safety Procedure Process Goes Electronic on Sept. 15
JLab's Operational Safety Procedure (OSP) process will go electronic on Sept. 15. The new electronic format will allow easier electronic distribution and enable faster electronic signature authority. OSPs or Temporary OSPs (TOSPs) currently documented in the system will not be affected and will remain in use until their assigned expiration date. Any TOSP/OSPs generated before Sept. 15 will be accepted into the current system until Sept. 30. (Exceptions after Sept. 30 will be handled on a case-by-case basis.) Any new TOSP/OSP generated after Sept. 15 must be submitted in the new electronic format for formal review and electronic signature processing. Online directions for the new electronic OSP forms will be published Sept. 15 in the ES&H Manual, Chapter 3310.

Studying the Quark-Gluon Plasma - Colloquium and Public Lecture
Johanna Stachel, Physikalisches Institut der Universitaet Heidelberg, will present "Studying the Quark-Gluon-Plasma in Nuclear Collisions at the LHC" in a colloquium on Wednesday, Aug. 22 in the CEBAF Center auditorium at 2 p.m. The theory of the strong interaction, quantum-chromodynamics, predicts for high temperature and density a new state of matter in which the confinement of quarks and gluons is lifted. This state, the quark-gluon plasma, existed in the early universe after the electroweak phase transition up to about 10 microseconds. In the past 25 years, accelerator-based experiments have been conducted in order to recreate this state of matter for a short time. In this talk, selected first results from the ALICE experiment, conducted
at the Large Hadron Collider at CERN, will be presented and discussed in the context of results at lower beam energies and theoretical interpretation.
