Researcher Relies on Jefferson Lab’s Powerful ‘Microscope’ to Study Weak Forces
Krishna Kumar has made it his life’s work to study the space within atoms. He pursues answers to life’s basic questions: Where did we come from? How are we put together? What happened right after the Big Bang?

Title: Optimization of Superconducting Cavities: Shape, Fields, Multipactor
Abstract: A method is discussed to search geometrical parameters of elliptical cavities to obtain the best possible figures of merit: B_pk/E_acc (peak magnetic field) and GR/Q (losses) for a given E_pk/E_acc (peak electric field), aperture, wall...
Title: Methods for high-precision determinations of radiative-leptonic decay form factors using lattice QCD
Abstract: In the region of hard photon energies, radiative leptonic decays of pseudoscalar mesons represent important probes of the internal structure of hadrons. Such decays are particularly interesting for...
New Accelerator Director Follows Technology, Oversees Accelerator Operations
Eduard Pozdeyev has made a career out of responding to the call for his expertise in designing and building equipment when an accelerator facility has required a large-scale equipment upgrade. Now, he is settling into his new, long-term role at the U.S. Department of Energy’s Thomas Jefferson National Accelerator Facility on the other side of the project life-cycle—as the director of accelerator operations for the lab’s Continuous Electron Beam Accelerator Facility (CEBAF).
Quantum Chromodynamics (QCD) is one of the pillars of the Standard Model of particle physics. It describes the strong interaction - one of the four fundamental forces of nature. This force holds quarks and gluons - collectively known as partons - together in hadrons such as the proton, and protons and neutrons together in atomic nuclei. QCD was developed and defined over a brief period from 1972 - 73. One hallmark of QCD is asymptotic freedom, which states that the strong force between quarks and gluons decreases with increasing energy. Asymptotic freedom was discovered in 1973 by David...
Title: Introduction and SCL3 Cryogenic Commissioning (First Run) of Cryogenic Systems for RAON Accelerator
Speaker: Taekyung Ki
Abstract: In South Korea, a heavy ion accelerator (RAON) aims to supply not only rare isotype beams, but also stable heavy ions by using the Isotope Separation On-Line (ISOL), In-flight Fragment (IF) separator, and two Super Conducting Linacs (SCL3 and...
