FGSAA NO LONGER REQUIRED FOR REGISTERED LAB USERS
The lab recently received clarification from the Department of Energy that Foreign Government Sponsored or Affiliated Activity (FGSAA) disclosures are not required from registered Jefferson Lab Users.
This clarification came after the lab submitted the initial report on User activities as required by the new FGSAA disclosure requirement, announced on Dec. 15, 2020, in this memo. After receiving our initial report, the DOE informed us it was not their intent to require disclosures from the User community, and this will be clarified in a subsequent version of the order.

FIRST ANALYSIS OF POLARIZED DIS DATA WITH SMALL-X HELICITY EVOLUTION
The JAM (Jefferson Lab Angular Momentum) collaboration has presented a Monte Carlo-based analysis of the combined world data on polarized lepton-nucleon deep-inelastic scattering at small Bjorken-x within the polarized quark-dipole formalism. The analysis shows for the first time that double-spin asymmetries at x < 0.1 can be described using only small-x evolution, allowing predictions to be made for the g_1 structure function at much smaller x. Anticipating future data from the Electron-Ion Collider, the paper also assesses the impact of electromagnetic and parity-violating polarization asymmetries on g_1, as well as demonstrates an extraction of the individual flavor helicity parton distributions at small x.
THEORY SEMINAR - ENRIQUE RICO - MARCH 8
On Monday, March 8 at 1 p.m., Enrique Rico of the University of the Basque Country will present "Quantum Simulation of Light-Front Parton Correlators" during the weekly Theory Seminar meeting. Join the discussion via BlueJeans.
Abstract: The physics of high-energy colliders relies on the knowledge of different non-perturbative parton correlators, such as parton distribution functions, that encode the information on universal hadron structure and are thus the main building blocks of any factorization theorem of the underlying process in such collisions. These functions are given in terms of gauge-invariant light-front operators, they are non-local in both space and real time, and are thus intractable by standard lattice techniques due to the well-known sign problem. In this paper, we propose a quantum algorithm to perform a quantum simulation of these types or this type of correlators, and illustrate it by considering a space-time Wilson loop. We discuss the implementation of the quantum algorithm in terms of quantum gates that are accessible within actual quantum technologies, such as cold atoms setups, trapped ions or superconducting circuits.
ACCELERATOR SEMINAR - QIONG WU - MARCH 4
On Thursday, March 4 at 11 a.m., Qiong Wu will present "SRF Challenges for the EIC Project" during an Accelerator Seminar meeting. Join via BlueJeans here. View the Accelerator Seminar meeting page here.
Abstract: The Electron-Ion Collider is designed for providing answers to the frontier questions of nuclear physics with studies through deep inelastic scattering. The realization of the EIC under current design is expected with challenging beam parameters and a wide range of both beam energy and species for collision. The superconducting radiofrequency systems are inevitably demanded for such a high-current machine operating at continuous wave mode. After decades of development, the demands from the EIC inspire the SRF technology to a new stage of achievement in all aspects from a project point of view. These high-performance while cost- and risk-minimizing requirements include novel cavity and coupler designs, simple and repeatable surface treatment techniques, flexible operation mode, powerful feedback systems and beyond.
NUCLEAR PHYSICISTS ON THE HUNT FOR SQUEEZED PROTONS
While protons populate the nucleus of every atom in the universe, sometimes they can be squeezed into a smaller size and slip out of the nucleus for a romp on their own. Observing these squeezed protons may offer unique insights into the particles that build our universe.
“We were looking to squeeze the proton such that its quarks are in a small-size configuration. And that’s a pretty tough thing to do,” says Holly Szumila-Vance.
Now, researchers hunting for these squeezed protons at the lab have come up empty-handed, suggesting there’s more to the phenomenon than first thought.
“This was an exciting experiment to be a part of. It was the first experiment to run in Experimental Hall C after we upgraded the hall for 12 GeV running,” said Szumila-Vance. “These were the highest-momentum protons measured at Jefferson Lab, and the highest-momentum protons ever produced by electron scattering.”
The result was recently published in Physical Review Letters.
SAFETY FLASH UPDATE - FAILURE TO IDENTIFY AND APPLY LO/TO ON POTENTIAL ENERGY SOURCE EVENT
There have been recent changes to the ES&H manual 3210 to include pre-job inspections regarding the review of engineered safety controls. This is a result of the investigation from the 1L13 Cathode Power Supply (CPS) notable event.

STATEWIDE TORNADO DRILL - MARCH 16
On Tuesday, March 16, the lab will participate in Virginia Severe Weather Awareness Week by observing and exercising our tornado drill siren. On-site supervisors will review the lab procedures for tornado warnings. To review the Emergency Response manual, click here. There will not be a tornado drill this Friday, March 5. For questions, contact Tina Johnson.
OPEN POSITIONS AT THE LAB
Jefferson Lab’s Human Resources department, in partnership with the Diversity & Inclusion Council, is excited to promote open positions within the lab! In response to feedback given during the Inclusion post-survey meetings, the lab community expressed interest in being notified of opportunities at the lab. Select job postings will now be published regularly in the JLab Weekly.
Here are this week's new openings:
Please note, job openings will be posted for a minimum of five days and are not guaranteed to be open for applications beyond this duration of time. For questions, contact Gina Lawson.
RESEARCH FELLOW TURNS TO ACCELERATOR POWER FOR WASTEWATER CLEANUP
Please join us in congratulating John Vennekate as the first recipient of the Hermann Grunder fellowship!
“It’s fitting that he will be pushing the boundaries of superconducting technologies with the goal of applying them in new ways to benefit society, something that was a high priority for Jefferson Lab’s founding director,” Jefferson Lab Director Stuart Henderson recently said.
The award is named in honor of Hermann Grunder, the founding director of Jefferson Lab. In addition to helping shape the lab into its current form, Grunder transformed the vision of the lab’s premier particle accelerator in the late 1980s, changing it to one that featured a new superconducting technology and recirculating design. The result was the design-specification-surpassing Continuous Electron Beam Accelerator Facility (CEBAF) that we know today. In honor of his contributions to accelerator science, Jefferson Lab recently established a fellowship in his name: the Hermann Grunder Postdoctoral Fellowship in Accelerator Science.

UPCOMING D&I DEMOGRAPHIC FOCUS GROUP MEETINGS
There are two remaining Diversity & Inclusion demographic focus group meetings left to attend this month. The purpose of these meetings is to promote a strong culture of diversity, inclusion and equity at the lab. The meetings hone in on demographics that reported a weaker sense of belonging at the lab according to last year’s Inclusion Survey. These listening sessions aim to understand why some groups feel this way and explore possible paths the lab can take to improve their sense of belonging in the future.
Upcoming demographic focus group meetings include:
