DOE HIGHLIGHTS JLAB-RAYTUM PARTNERSHIP
During a recent presentation to the DOE Office of Science, the collaboration between Jefferson Lab and Raytum was highlighted as a Small Business Innovation Research (SBIR) success story. New Jefferson Lab experiments call for increasingly demanding requirements where existing products were hard to find. Via the SBIR program, Raytum developed powerful (30-50W) narrow-width lasers with adjustability, which performed exceptionally well during the last round of experiments. Following this success, Raytum is currently generating next-generation lasers (200W) needed for future Jefferson Lab experiments. Furthermore, Raytum and Jefferson Lab partnered together to design and develop optical-fiber combiners, as well as other optical setups for their next polarized target project in Hall A or C.

B-MESON LOFFE-TIME DISTRIBUTION AMPLITUDE AT SHORT DISTANCES
In a new paper, the formalism of parton pseudo-distributions, recently developed at Jefferson Lab, was extended and applied to distribution amplitudes (DAs) of heavy-light systems, such as the B-meson. The new approach allows one to compute the DAs using the matching relation derived in the paper, which maps the light-cone DA onto the reduced Ioffe-time distribution amplitude measurable on the Euclidean lattice.

THEORY SEMINAR - GUMARO RENDON - JUNE 29
On Monday, June 29 at 1 p.m., Gumaro Rendon of Brookhaven National Laboratory will give a talk on "The κ and K* resonances from lattice QCD" during the virtual Theory Seminar series.
Abstract: Rendon will present a lattice-QCD determination of the elastic isospin-1/2 S-wave and P-wave Kπ scattering amplitudes as a function of the center-of-mass energy using Lüscher’s method. He will perform global fits of K-matrix parametrizations to the finite-volume energy spectra for all irreducible representations with total momenta up to √3*2π/L; this includes irreps that mix the S- and P-waves. Several different parametrizations for the energy dependence of the K-matrix are considered. He will also determine the positions of the nearest poles in the scattering amplitudes, which correspond to the broad κ resonance in the S-wave and the narrow K*(892) resonance in the P-wave. The calculations are performed with 2 + 1 dynamical clover fermions for two different pion masses of 317.2(2.2) and 175.9(1.8) MeV.

ENERGY REDUCTION TEST - JUNE 25
Jefferson Lab will participate in a region-wide test on Thursday, June 25, from 1:45-3:15 p.m., to significantly reduce the electricity it draws from the power grid.
 
The Facilities Division, in coordination with the Accelerator, Engineering and Physics divisions, will conduct a voluntary power reduction test at the lab involving the shifting and reduction of electrical loads on the campus, as well as load control on the accelerator site.

AMBER BOEHNLEIN NAMED AD FOR NEW CST DIVISION
Computer scientists, software developers and system administrators have come together under the newly established Computational Sciences and Technology Division. Amber Boehnlein, Jefferson Lab’s chief information officer, has been promoted to associate director for computational sciences and technology, heading up the new division.

“My journey has given me the chance to work in multiple laboratories and to influence the interplay of scientific research and computing. The creation of this division feels like the culmination of what I have learned in each of those positions, and I’m looking forward to bringing all of that experience to bear,” she said.

WINDOWS PATCHES DEPLOYMENT - JUNE 24
The CST Division plans to release Windows patches on Wednesday, June 24. To finalize these patch installations, plan on rebooting your desktop no later than Friday, June 26.

Read the full memo here.
For questions, contact the CST Division Help Desk at x7155.

THUNDERBIRD AND OFFICE 365 PASSWORD UPDATES
Those who utilize Thunderbird with Office 365, should be aware that your application password may be close to expiring. If you find that you can no longer log in to Office 365 while using Thunderbird, your application password may have already expired. To create a new one, log in to Office 365 online and go through the process of generating a new one.

Instructions can be found how to create a new password by clicking here.
For questions, contact the CST Division Help Desk at x7155.

 

QUESTIONING YOUR FINANCIAL FUTURE? TIAA OFFERS SUMMER WEBINARS 
TIAA has developed a series of live educational webinars to provide insight on a wide range of popular financial topics. Each webinar includes an interactive Q&A session with TIAA professionals.

Register for any of the following webinars by visiting www.tiaa.org/webinars. Pre-registration is required to participate in all of the live webinars. All webinars will be available for viewing for 30 days after their air date.

View the full summer webinar series schedule in the internal memo here.
For questions, contact Treva Ferguson.

 

JLAB GRADUATE STUDENT RESEARCHERS RECEIVE DOE AWARDS
Three graduate students have gotten a financial boost from DOE to conduct research at Jefferson Lab. The students have received supplemental research awards from the DOE Office of Science Graduate Student Research Program (SCGSR).
  • Casey Alan Morean, University of Tennessee.
  • John Alan Boyd, University of Virginia.
  • Sean Jeffas, University of Virginia.

All three awardees are involved in experiments at Jefferson Lab in pursuit of their Ph.D.s. in nuclear physics.

CAMILLE GINSBURG NAMED NEW D&I CO-CHAIR
Camille Ginsburg has accepted a position as the new Diversity and Inclusion Co-Chair for Jefferson Lab. Camille will serve alongside Rolf Ent to enhance both diversity and inclusion, collect insights from colleagues across the organization, serve as a catalyst for change, and monitor progress of this initiative.

When asked about the importance of diversity and inclusion in her new role, Camille shared "While our current lack of diversity in the field is a highly complex issue without any easy solutions, we can make significant contributions at the lab level toward developing an inclusive climate, providing effective mentoring, and addressing implicit bias, at the lab level."

SPOTLIGHT ON JIM FOLLKIE - SENIOR TECHNOLOGIST

At a glance, one might say that Jim Follkie has a need for speed – or at least to have a role in making things go very fast. Through his job at Jefferson Lab, Follkie has the distinction of being one of a few dozen people in the world who can perform an electron beam weld on niobium, which he does from behind the three-inch lead glass of an eight-foot by eight-foot cubed vacuum chamber.
