Photo Trivia for Records and Information Management Month
April is Records and Information Management Month, and the Jefferson Lab Archives Staff need your help! This is your chance to use your knowledge of Jefferson Lab and the people that have worked here over the years. Each week, beginning today, a new collage of photos will be displayed in the CEBAF Center atrium. Jefferson Lab staff and Users are asked to look at the old photos and identify its people, places and things. Each photo on display will correspond to a field on forms provided. Complete and drop off the forms in the box, which will be available during the entry period. Forms with the most correctly completed fields will be placed in a weekly drawing for a Starbucks gift card, courtesy of the Jefferson Lab Archives staff. For those who are unable to identify any of the individuals or objects, you can still play along and fill out the forms to the best of your knowledge. At the end of April, all forms received will be eligible for the last drawing gift card.
Entry periods will be as follows:
Wednesday, March 29 through Tuesday, April 4
Wednesday, April 5 through Tuesday, April 11
Wednesday, April 12 through Tuesday, April 18
Wednesday, April 19 through Tuesday, April 25
Wednesday, April 26 through Tuesday, May 2
Winners will be announced in the subsequent JLab Weekly Briefs. Prize can be picked up from the library. If you have any questions about the trivia challenge, contact Kim Edwards at email@example.com.
Last Chance to Apply for Sabbatical and Research Leave Support at Jefferson Lab
The JSA/JLab Sabbatical and Research Leave Support Program enhances research opportunities for faculty through access to Jefferson Lab facilities and interaction with Lab researchers and users, strengthens the teaching and research capabilities of universities through faculty involvement, and strengthens the research programs of Jefferson Lab by attracting "new blood" and integrating university faculty members in the laboratory's programs. Application materials are due by March 31. More information and applications requirements can be found online.
Center for Theoretical and Computational PhysicsA new paper addresses a critical issue in first principles lattice QCD calculations, namely, nonperturbative renormalisation of currents. Using these results, the most accurate calculations to date have been achieved for the mass and decay constant of the φ vector meson. This work can be extended to compute pseudoscalar and vector meson electromagnetic form factors at high momentum transfer, relevant to the Jefferson Lab 12 GeV experimental physics program.
EngineeringThe Metrology Group has completed many tasks in the last two months, including:
In Hall A, the group has completed eight surveys of both the right and left spectrometers. Additionally, the Hall A target was aligned as required after repairs. A system was developed to process all 36 of the various detectors located on Hall B's forward carriage. This will allow rapid calculation of all the detector locations after the forward carriage is moved, relative to the target. Additional work completed in Hall B include the alignment of the central time of flights and many other components in the beamline to prepare for the Key Performance Parameter run.
In Hall C, the survey network of monuments in the hall and on the Super High Momentum Spectrometer (SHMS) and HMS were updated to take into account deflections of the floor due to the increased weight of the spectrometers. Also in conjunction with meeting Hall C's KPP, the target can, beamline, superharps and the beam dump were aligned to specification parameters. All five major magnets on the SHMS have been installed
Over in the CEBAF Accelerator, the beam chopper in the injector was aligned to assist with beam delivery. All survey monuments were also monitored in the accelerator. The monitoring helps track tunnel movements, which is fed to beam operations. Small movements in the tunnel affect beam steering. The alignment crews also assisted in the repair/replacement of the RF separators earlier in the year. Support for the UITF also continues as beamline components are installed.
Work also continues supporting the LCLS-II project. One of the many jobs the crews completed was monitoring the prototype cryomodule before and after the test road trip.
Finally, the magnet measurement group restored the five-meter test stand to operational status.
Environment, Safety, Health and QualityEmergency Manager Thanks Lab Community for Time on Tornado Preparedness
Jefferson Lab Emergency Manager, Tina Menefee, commends all the supervisors and members of the lab community who took the time last week (March 20-24) to review the tornado preparedness procedures. Menefee has received some very useful feedback regarding the lab’s tornado preparedness efforts and encourages anyone with feedback, ideas or suggestions to send them to her at: firstname.lastname@example.org.
AnnouncementsDOE Women in STEM Panel Discussion Today at 10 a.m.
