  • Nuclear physicists have found that the internal structures of protons and neutrons may be altered in different ways inside nuclei

  • A precision measurement of the neutron skin in a calcium nucleus surprisingly reveals a thinner skin than expected from a similar measurement in lead

  • EIC Center at Jefferson Lab

    The Electron-Ion Collider Center at Jefferson Lab (EIC2@JLab) is an organization to advance and promote the science program at a future electron-ion collider (EIC) facility. Particular emphasis is on the close connection of EIC science to the current Jefferson Lab 12 GeV CEBAF science program.   

    "EIC Center"At the heart of the atom are protons and neutrons. The characteristics and interactions of neutrons and protons, singly and collectively in the nuclei are responsible for how our cosmos developed and how our sun provides the heat that sustains the eco-system on earth. 

    While we have known for 50 years that protons and neutrons are made of quarks and gluons (represented in the figure to the left as spheres with arrows and springs, respectively), we are just beginning to learn how to image the structure and interactions inside protons and neutrons that are at the femto-scale, a million times smaller than the nano-scale of modern micro-electronics.

    Jefferson Lab has been at the forefront of this research; the current 12 GeV CEBAF program at JLab is world-leading in this science. The proposed Electron-Ion Collider will be the ultimate instrument for this new science: nuclear femtography.

  • Vision: Partnering with our customers, we provide support to further the laboratory's mission to operate a world class user facility for conducting nuclear physics research. Our focus is to provide project management and integrated planning support across the Lab that is aligned with Lab goals, objectives and guidance.

  • The Chief Planning Officer coordinates and manages the allocation of laboratory resources and budgets across the divisions, including internally and externally funded projects, and facilitates development of the laboratory’s operations and research budgets with the Department of Energy’s Office of Nuclear Physics.

    These functions include:

  • Nuclear theorists put pen to paper and code to computer to detail a subatomic particle’s inner structure.

  • Physicists develop a universal function that suggests that proton-neutron pairs in the nucleus may explain why quarks inside nuclei have lower average momenta than predicted.

  • Built with detector technologies used in nuclear physics experiments, the system monitors radiation treatments in hard-to-reach areas.
