Jefferson Lab Weekly Briefs
February 25, 2015
12 GeV UpgradeThe first 12 GeV Hall C magnet, Q1, which arrived in January, has been installed on the Super High Momentum Spectrometer (SHMS) carriage and connected to its cryogenic, power, and control systems. Following a checkout of those services, this superconducting magnet is now being cooled-down in preparation for its final acceptance tests. Close on its heels is the Horizontal Bend (HB) magnet, which is in its final week of construction at Michigan State University. The remaining three SHMS magnets are making steady progress, with the two coils for the dipole having been bonded together, and the final two (of eight) Q2 and Q3 coils now on the winding machines. On the SHMS, the calorimeters have been installed, and now the stands and frames for the remaining detectors have been trial-fitted in the shield house to assure that detector installations may proceed smoothly. Cables for the detectors are being installed now, as are the floor scales that provide experimenters with a precise measurement of the spectrometer angle.

JSA Minority/Female Undergraduate Research Assistantship
Jefferson Lab is seeking candidates for a Research Assistantship. JSA will provide funds to support a junior or senior level student at the university during the 2015-2016 academic year. This project is supported by the JSA Initiatives Fund Program, a commitment from the JSA owners, SURA and PAE Applied Technologies. These funds support programs, initiatives, and activities that further the scientific outreach, promote the science, education and technology of the Jefferson Lab and benefit the lab’s extended user community in ways that complement the lab’s basic and applied research missions. In recent years, students have used the funds to aid the exploration of 3D printed scintillator detectors for the study of field emission in accelerating cavities, as well as a presentation at the SESAPS conference on work done on the PrimEx-II Collaboration. Nominations will be accepted through April 17. For more information, visit the website.
2014 JSA Thesis Prize Nominations Accepted
The Users Group Board of Directors is now accepting nominations for the 2014 JSA Thesis Prize for the best Jefferson Lab-related thesis. The prize is supported by the JSA Initiatives Fund Program. A complete package requires a nomination letter by a senior scientist giving the name and institution of the person being nominated and the names of three people who will send letters of recommendation, along with a copy of the thesis. All materials must be submitted electronically. The three letters of recommendation must be sent before the deadline. Theses completed during the calendar year 2014 are eligible, as well as theses completed during the last quarter of 2013 (if they haven't been submitted before). All materials must be sent by email to Lorelei Chopard by the nomination deadline of March 2. If you have any questions about the prize, contact John Arrington.
JSA Accepting Applications for 2015-16 Sabbatical Leave Support Program
Jefferson Science Associates is currently accepting applications for the JSA/JLab Sabbatical Leave Support Program for academic year 2015-16 at Jefferson Lab. The JSA/JLab Sabbatical Leave Support Program is supported by the JSA Initiatives Fund. Materials should be submitted via email to firstname.lastname@example.org with the subject line "JSA Sabbatical Support" by March 2. See the full announcement.
Center for Theoretical and Computational PhysicsA new paper presents a method to study 0-to-2 and 1-to-2 transition amplitudes directly from lattice QCD. This method will allow for future studies of meson photoproduction, heavy meson and resonance decays, and deuteron photo-disintegration, among other phenomenologically important processes. The paper discusses an example of relevance to Jefferson Lab, N+γ → (N+π, N+η, N+η', Σ+K, Λ+K), where two-body, coupled channels are accommodated.
EngineeringThe Alignment group has been busy finishing up the work in all the halls and CEBAF Accelerator to get ready for lock-up and running. Some of the activities in the past five weeks were:
Environment, Safety, Health & Quality
Proper Use of Home Pesticides
Jefferson Lab employees have had training about reading and understanding a chemical hazard and properties. Never buy a product to use around your family and pets when there are no warning or instructions on the label, and always follow the label directions to use safely.
