All-Hands Meetings Scheduled Director Stuart Henderson will speak about the recent DOE site selection decision for a future Electron-Ion Collider on Jan. 16, at 2:30-3:30 p.m. and Jan. 17, at 9-10 a.m.
ACCELERATOR STATUS A message from Camille Ginsburg, director of Accelerator Operations:
Over the holiday break, we left some systems on, or nominally on, to facilitate a quicker start-up after the new year, primarily to keep the tunnel at operational temperatures to reduce potential beam pathlength changes and minimize component power cycling. Global support systems such as electrical power, low-conductivity water (LCW), 2K cryogenics, air conditioning, safety systems, vacuum, etc. remained functional so that these conditions could be maintained. This special setup required critical support staff to be on-call 24/7 and operations staff to work in the control room throughout the holiday. CEBAF restarted rather quickly after the break. I greatly appreciate the exceptional commitment to the laboratory of all who worked over the holidays to contribute to our success.
CEBAF was returned to physics operating conditions by Jan. 10, as planned, but we have not yet achieved four-hall operation. THREE BODY SPECTRUM FROM LATTICE QCD - PAPER
Researchers in the lattice QCD group at George Washington University have calculated and interpreted the energy spectrum of three pions at maximal isospin in a finite volume. The predictions from a finite-volume formalism based on three-body unitarity match the lattice QCD energies for different pion masses, spatial elongations and moving frames. The results encourage future studies of more complicated few-body systems.
DEEP LEARNING JET SUBSTRUCTURE FROM TWO-PARTICLE CORRELATION - JAN. 22
On Wednesday, Jan. 22 at 1 p.m., Yang-Ting Chien (YITP, Stony Brook) will discuss "Deep Learning Jet Substructure from Two-Particle Correlation" during next week's Theory seminar. For more details, including the abstract, click here. Stay informed about upcoming Theory seminars here.
EVERY VOICE COUNTS - INCLUSION SURVEY OPEN THROUGH JAN. 28
On Thursday, Jan. 9, you received an email from the third-party vendor, Culture Amp, requesting that you take a confidential survey on inclusion. The survey link from that email will remain open until Tuesday, Jan. 28. The Inclusion Survey announcement email can be found here.
The goal of the Inclusion Survey is to measure lab culture from an inclusion lens. The survey centers around themes that include fairness, belonging, decision-making and voice. Your response will allow lab leadership to understand the current lab culture and have the ability to make decisions based on those results.
Official limited-edition JLab commemorative coins will be available for those who complete the survey. After the survey closes, an announcement email will detail how to retrieve your coin.
PRESSURESYSTEMS SAFETY AWARENESS - JAN. 24
The lab is offering a Pressure Systems Safety Awareness (SAF130A) course on Friday, Jan. 24, from 1-3 p.m., in CEBAF Center room F224-225. The course will cover basic safety considerations and provide insight into the required process for design, fabrication, testing, inspection, maintenance, repair and operation of pressure systems. Led by Engineering Division Manager Will Oren, the training is open to all but will be especially beneficial for operators and technician supervisors. To register for SAF130A, click here. For questions, contact Erica Jonesat x5699.
IT DIVISION MAINTENANCE - JAN. 21
The Information Technology (IT) Division has scheduled a maintenance period on Tuesday, Jan. 21, from 5-10 p.m. During this maintenance, the IT Division will update the current JLABTS terminal servers to Windows Server 2019. There will be short network outages to the Test Lab Annex and the Support Services Center (SSC) buildings while network switches are updated. There will also be intermittent wireless outages in the Test Lab and the Technology & Engineering Development Bldg. (TED) while new wireless access points are replaced.
Core Common User Environment (CUE) software, such as Thunderbird and Firefox will also be updated.
Finally, IT will release updates to all Windows and Linux desktop and servers. Reboots of Windows and Linux servers are scheduled overnight to ensure that patch installation is finalized. Please plan on rebooting your CUE-managed Windows or Linux desktop by Friday, Jan. 24, order to finalize patch installation. If you have any questions or concerns regarding these maintenance activities, please contact the IT Division Help Desk at x7770.
JSA AWARDS $449,000 FOR FY20 INITIATIVES FUND PROGRAM
Jefferson Science Associates (JSA) has announced the award of $449,000 to support projects related to education, outreach and career development to staff and Users at Jefferson Lab. “The Initiatives Fund is an important investment by JSA to directly support the lab’s mission of scientific discovery and its application to benefit society. The program is recognized for its impact on the education and training of the next generation of scientists through its fellowships, postdoc research grants, and K-12 projects," says Lab Director Stuart Henderson. Read the full announcement here.
THROW PARTIES, BUILD LAB CULTURE AND HAVE FUN! As we jump into a new year, the Jefferson Lab Activities Group (JAG) is putting out a call for those in the wider community that would like to be a part of something outside of their regular employee role at the lab. JAG is behind the Run-A-Round, Oktoberfest, the Children's Holiday Party and more! The JAG is currently seeking an infusion of new ideas to help broaden the committee’s perspective and to keep it energized!
CHESAPEAKE REGIONAL MOBILE MAMMOGRAPHY ON-SITE - JAN. 31
The Chesapeake Regional Mobile Mammography Unit will be at Jefferson Lab on Jan. 31 from 9 a.m.-3 p.m. It will be stationed in the Applied Research Center (ARC) parking lot. Both 2D and 3D options are offered. This service is open to all employees, Users, contractors, etc. as well as their family members or friends. Personal health insurance will be billed. Appointments are limited, so be sure to reserve your space by calling (757) 312-6400 or visiting www.chesapeakemammo.com.
