12 GeV Upgrade

The summer scheduled accelerator down work continues, with a major focus on the Utilities Infrastructure Modernization  (UIM) project. As the UIM project progresses, there will be several extended outages in both the low-conductivity water and the electrical power delivery throughout the facility. These outages are being closely coordinated with the planned 12 GeV Upgrade work. Hall D is nearing the start of commissioning activities with the recent experimental readiness review held on July 1 and 2. The pre-bid vendor meeting was held for the installation of the Hall C magnet yoke assemblies. This activity will involve heavy material handling and crane lifts. When the work commences, all personnel in the hall will need to be aware of the posted boundaries. The work is expected to be complete by the end of August.

Center for Theoretical and Computational Physics

The semileptonic weak decays of hyperons offer an alternative way to determine the fundamental weak interaction parameter, Vus, whose accurate knowledge is necessary for testing the Standard Model of electroweak interactions. Its most precise determination is from the semileptonic decays of K mesons, but an improved theoretical description of the form factors of the weak decays of hyperons, together with improved experimental measurements, would make hyperon decays competitive with the K decays. In a new paper the the corrections to the vector current form factor f1 are calculated in a novel framework based on chiral perturbation theory and the 1/Nc expansion of QCD, and the results used to give an appraisal of the current status of hyperon decays.


The Mechanical Engineering (ME) group is awaiting the final components to complete the new girders and stands for Hall B's Heavy Photo Search II experiment. All of the parts are due within the next couple of weeks. The Hall A dump work continues, with testing of the repair made to the dump flange weld and with getting the final mechanical parts procured for the diffuser and isolation wall. The associated vacuum pipe is due within the next one-two weeks. A significant effort has been expended over the past two weeks to detail drawings for the Hall B magnet distribution can. Currently, 95 of 99 drawings are detailed and being checked.

A date has been set for the kickoff of the GD&T Lunch and Learn training. The first session will be Wednesday, July 30, noon-1 p.m. Feel free to bring your lunch. If you have not yet declared your interest, R.S.V.P. to Tim Michalski. A meeting invitation will be sent out to those who have expressed interest in participating.

Facilities Management & Logistics

Jefferson Lab Annual Property Inventory Starts Soon
The annual property inventory starts the week of July 14 and runs through September 12. The property manager has randomly selected 20 percent of Jefferson Lab's property custodians for this year's property inventory. Those custodians will be contacted by a member of the property staff. In addition, any custodians that did not complete the annual property validation will also be included in the inventory group for this year.

To complete the inventory, each item must be physically seen by a member of the property office. Note that the property custodian is responsible to know and search, if needed, for their assigned property, not the property staff. Property staff will go to the location identified for each item during the property validation to inventory the property. The assigned custodian will be notified of any item not located at its specified location, and the item will be reported as "missing" until the item is physically located by the custodian and verified by property staff. If you have questions, contact Christian Whalen at x5899.

    Environment, Safety, Health and Quality

    Ladder Safety at Jefferson Lab
    Did you know that before using a ladder here at Jefferson Lab, you must complete the Ladder Safety course, SAF 307? One would think that using a ladder is straightforward, but many accidents occur when ladders are misused - sometimes even on purpose!

    A recent ladder inspection at another lab uncovered a number of structural defects on many ladders. While the ladders may not have failed with the next climber, a shift in the weight or type of surface could have caused it to collapse under that person. Do you conduct a cursory inspection before you use a ladder? A quick look over the ladder's feet, joints, side-rails and rungs is always good practice. ES&H Manual Chapter 6132 Ladder and Scaffold Safety is a good reference for the safe use of ladders. Also read the "how to use" instruction labels and obey the load rating for the ladder you are using. Jefferson Lab uses only ANSI Type 1 (250 pounds or greater load rating) ladders. If do find or suspect a defective ladder, immediately tag it out or label it as such and submit a Facilities Management Work Request.

    Computing and Networking Infrastructure

    CNI Maintenance Period Set for Tuesday, July 15, 5-10 p.m.
    CNI is planning a maintenance period on Tuesday, July 15, 5-10 p.m. During this time, a central file server will be rebooted to install an operating system upgrade. For Windows users, this will affect the K, L and M drives. For Unix/Mac users, this will affect the /apps, /site, /group and /mss areas. There will also be a short interruption to the Internet from onsite. Patches will be released to all Linux and Windows desktops. Plan on rebooting your desktop system on either Wednesday or Thursday to finalize the patch installation. If you have any questions or concerns about these maintenance activities, please contact the IT Division Helpdesk, x7155.

    ReadyTalk End-of-Life
    ReadyTalk is an audio, video and web conferencing service that was offered by ESnet Collaboration Services (ECS) and will be discontinued by the lab's provider on Sept. 30. BlueJeans will become the primary option for audio and video conferencing. Like ReadyTalk, BlueJeans provides audio conferencing, H.323 video conferencing and web conferencing. Jefferson Lab will end support for ReadyTalk by Aug. 1.

    To assist with an easy migration, there will be training sessions held on July 10 and July 23 at 2 p.m. in CEBAF Center room F113. ReadyTalk was mainly used for audio conferencing, therefore, audio conferencing will be the focus of these training sessions. There will be time at the end of each session for all questions regarding BlueJeans (H.323, web conferencing, etc.). To learn more, visit the BlueJeans webpage for information on logging in and configuring BlueJeans with your Jefferson Lab computer account.

    Last Chance to Renew Your SmartCard
    If you have a Jefferson Lab SmartCard, you must renew your SmartCard by visiting the IT Division Helpdesk before July 11. For security reasons, Jefferson Lab SmartCards expire every three years, which means they must be renewed to continue functioning. In addition, the CNI group is making other changes to the SmartCard system that will require all cards to be renewed (even if issued recently).

    To avoid problems and delays, be sure to have your card renewed before July 11. Once the expiration date passes, the card will no longer work, and the user will not be able to log in to Jefferson Lab systems using the card. If you have any questions or concerns, contact the IT Division Helpdesk, x7155.


    Upcoming Changes to the Requisition System
    On Tuesday, July 15, Jefferson Lab's requisition system, Maximo, will be updated to include new functionality to improve ordering and processing of equipment at the laboratory. Two new questions will be added to the “Other Information” section for network-enabled and calibration equipment. Also, all Electronic Data Processing (EDP) equipment subject to EPEAT (Electronic Product Environmental Assessment Tool) requirements will now require EPEAT documentation to be attached to the requisition. For more information, visit the Computer Center website. If you have any questions, join IT Division staff on Friday, July 11, for a Q&A session at 9 a.m. in CEBAF Center room F113. Alternatively, feel free to send any questions to the IT Division Helpdesk, x7155.
