  • Thomas Jefferson National Accelerator Facility (Jefferson Lab) provides scientists worldwide the lab’s unique particle accelerator, known as the Continuous Electron Beam Accelerator Facility (CEBAF), to probe the most basic building blocks of matter by conducting research at the frontiers of nuclear physics (NP) and related disciplines. In addition, the lab capitalizes on its unique technologies and expertise to perform advanced computing and applied research with industry and university partners, and provides programs designed to help educate the next generation in science and technology.

    Majority of computational science activities in Jefferson Lab focus on these areas : large scale and numerical intensive Lattice Quantum Chromodynamics (LQCD) calculations, modeling and simulation of accelerators and the experiment detectors, fast data acquisition and streaming data readout, high throughput computing for data analysis of experimental data, and large scale distributed data storage and management.

    Many Jefferson Lab scientists and staffs lead or actively participate the computational efforts in the above areas. Among those are computer/computational scientists and computer professionals from newly formed computational sciences and technology division (CST), physicists from physics division and the Center for Theoretical and Computational Physics, and accelerator physicists from Center for Advanced Studies of Accelerators (CASA). In addition, collaborations with universities and industrial partners further research and development in computational science.

    Jefferson Lab maintains various state of art high performance computing resources onsite. CSGF students will utilize these resources to carried out their researches in the specific areas described below:

    Accelerator Modeling

    CASA and Jefferson Lab SRF institute focus on advanced algorithms, such as fast multipole methods, for multiparticle accelerator dynamics simulations, artificial intelligence (AI) and machine learning (ML) applied to superconducting RF (SRF) accelerator operations, and integrated large and multi-scale modeling of SRF accelerator structures. These areas will be an essential part of a national strategy to optimize DOE operational facility investments, and to strengthen Jefferson Lab’s core competency of world-leading SRF advanced design and facility operations. Especially, current active simulation projects

    like electron cooling, intra-beam scattering, and coherent synchrotron radiation present diverse research domains ranging from numerical algorithms development to parallel computing.

    Streaming Data Readout

    With tremendous advancement in micro-electronics and computing technologies in the last decade, many nuclear physics and high-energy physics experiments are taking advantage of these developments by upgrading their existing triggered data acquisition to a streaming readout model (SRO) , whereby detectors are continuously read out in parallel streams of data. An SRO system, which could handle up to 100 Gb/s data throughput, provides a pipelined data analysis model to nuclear physics experiments where data are analyzed and processed in near real-time fashion. Jefferson Lab is leading a collaborative research and development effort to devise SRO systems not only for CEBAF 12GeV experiments but also for the upcoming EIC facility. SRO development offers CSGF students some exciting research areas such as network protocol design, high speed data communication, high performance data compression and distributed computing.

    Physics Data Analysis

    Analysis of data from modern particle physics experiments uses technically advanced programming and computing techniques to handle the large volumes of data. One not only needs to understand aspects of parallel programming using modern languages such as C/C++, Java, and Python, but also must incorporate knowledge of experimental techniques involving error propagation and estimation in order to properly interpret the results. Aspects of this range from writing a single algorithm used in event reconstruction, to using the collection of algorithms written by others, to managing campaigns at HPC facilities that apply these algorithms to large datasets. Detector calibrations and final physics analysis are also significant parts of the analysis chain. CSGF students could participate in any of these areas.

    Machine Learning

    Rapid developments in hardware computational power and an ever increasing set of data has lead to explosive growth in machine learning techniques, specifically deep learning techniques. These techniques threaten to change just about every facet of modern life and nuclear physics is no exception. At Jefferson Lab machine learning is being developed for every step in the physics workflow. To deliver beam to the experimental halls the accelerator relies on radio frequency (RF) cavities to accelerate the electrons. Occasionally these cavities, of which there are over 400 in operation around the accelerator, fault which disrupts the delivery of the beam to experiments. To quickly identify and diagnose cavity faults A.I. is being developed and deployed. Experiments themselves are developing and/or deploying A.I. to monitor detector performance, decide what data to keep, reconstruct detector responses, simulate the detectors, and even to analyze collected data. With the active development of machine learning tools and techniques Jefferson Lab hopes to drive nuclear physics research forward, enabling physicists to more quickly obtain and analyze high quality data.

      A family history in art

      Joanna Griffin, a Graphic Designer for Jefferson Lab, smiles when recalling sweet memories of her first exposure to art: painting alongside her mother. 

      The daughter of a Swedish artist and a Ukrainian civil engineer for the United States government, Griffin spent most of her childhood traveling. Her father, who speaks seven languages, took full advantage of international work opportunities.

      Her 7 childhood homes throughout Sweden, Germany, Belgium, and Panama, provided Griffin’s mother with endless images of nature to capture with her oils on canvas.  “We would put music on and paint together,” Griffin recalls, remembering the nurturing guidance of her mother as she taught her daughter different techniques. “We would pick different things to paint… she’s a beautiful person.” 

      Inspired and encouraged by her mother, Joanna began a lifelong journey that has combined a love of art with an appreciation of diverse cultures, and a genuine caring for people in need. 

      Growing up in a traveling family, Griffin developed a deep love for history, the arts, culinary innovations and experiencing different cultures. She attended English-speaking schools throughout Europe, until she entered high school in York County, the place where she first met her future husband.

      After graduating high school, Griffin who loves classical music, studied at William & Mary and art schools in Sweden. Then, one day, she received a handwritten letter from an old high school friend, who was now a U.S. Marine. “The letter said he didn’t know if I was still thinking about him, but he thought about me every day,” Griffin said. “I still have the letter.” 

      Soon, they married and formed a life together dedicated to the things most important to both of them – family, work, and service to others.

      The art of science

      The Griffins lived in North Carolina until her husband, Michael, had finished his time as a Marine. A move back to Newport News ended up being a life-changing moment for Griffin, when her mother-in-law told her about a class in Photoshop at Thomas Nelson Community College. “I didn’t know that there was a field in graphic arts,” Griffin said. “After taking that class, I felt it was the direction I wanted to go.”

      Griffin finished her associate’s degree in graphic arts, and started an internship with Jefferson Lab that eventually turned into a full-time position.  Griffin has served as a Staff Graphic Artist at Jefferson Lab for 10 years now.  “I’m depicting the science,” Griffin said. “My job is to translate ideas that people have into something that is more concrete and relatable to the public.”

      This is not always easy. Often times, Griffin finds herself sitting in a room of physicists who may not agree on how the science should be depicted. An example is quarks, “We’re trying to illustrate something that nobody has ever seen,” Griffin said. “They’ll argue on which way I should portray it. It never gets boring.”

      Many hours of brainstorming, research, drafts and edits go into creating images of unseen science. It is a learning curve that Griffin has had to overcome. “The physicists take the time to explain what it is,” Griffin said, mentioning they will draw out a bare-bone skeleton and “I just try to make it prettier.”

      Using Photoshop, Illustrator, InDesign and a tablet for drawing, Griffin creates images as scientifically correct as imaginable and makes them understandable and accessible to the general public. “I love the traditional arts and being able to incorporate that into a career is really ideal for me,” Griffin said. “I love the creative process.”

      Bringing science to the public

      As a Graphic Designer, Griffin works to make intricate sciences more accessible to the public through detailed visuals. “I love the creative process,” Griffin said. “We’re customer based, so anyone from the lab can come to us to request a poster, an illustration. They present to us what they’re looking for, and we brainstorm ideas. We gather what it is they’re looking for. We present a couple of drafts, and there’s a little back and forth to finalize it.”

      She feels her work at Jefferson Lab is aligned with her desire to help people. Griffin's sticky notes of detailed to-do lists are all detailed requests from physicists working on research, patents, papers or conferences who all need images from her. During role-model visits through Jefferson Lab’s Education Department, students from local schools have observed her work. “We’re able to show kids a world of possibilities,” Griffin said. “The kind of careers that are out there and what they can get interested in.”

      Griffin also occasionally appears as the co-host on Frostbite Theater, the brain child of Steve Gagnon in the Education Department, where you can find her freezing balloons with liquid nitrogen. Griffin feels she found the ideal situation for her that combines her desire to help people, her passion for the arts, and her general curiosity in everything.  “As corny as it sounds, I like helping people,” Griffin said. “What I do, does that. Helping the scientists get images, helping their patents be more relatable. I’m support for the physicists.”

      A passion for volunteering

      Griffin’s office is peppered with vibrant posters of her travels and photographs of her family. Reminders of the journeys she’s traveled, and the people she loves. Every morning, before coming into work, she sees a Bible verse that she hand wrote on a chalkboard in her home. “It’s Galatians 6:9,” She said. “It says ‘Don’t grow weary of doing good.’ I take that very seriously.”

      When she isn’t working, Griffin enjoys spending time with her husband, Michael, and two young boys, Jonathan and Joshua. She is also a hospice volunteer with Bon Secours, a role she embraced after experiencing the death of her young son’s teacher. 

      Griffin strives to live a life full of art, love and giving. Ask her how she’d like to be remembered, and with confidence she’ll say: “I hope that I make an impact within my sphere of influence,” Griffin said. “And that I loved people well.”
