  1. Nuclear Physics Part 2: The GlueX Project UConn Mentor Connection Mariel Tader Mentor: Dr. Richard Jones

  2. The Project • Thomas Jefferson National Accelerator Facility • The collaboration • Will be the first to observe and study exotic mesons • Will begin 2014 UConn Mentor Connection 2010, Mariel Tader

  3. GlueX hopes to learn about quarks, gluons, and confinement by creating exotic mesons • How we “see” the gluons: Polarized beam liquid hydrogen target exotic mesons final particles and radiation data deciphered UConn Mentor Connection 2010, Mariel Tader

  4. The Process • Electron beam diamond wafer polarized photons hit mesons detectors UConn Mentor Connection 2010, Mariel Tader

  5. Bremsstrahlung • German for “braking radiation” • A radiation particle interacts with atoms and creates more radiation, while losing the corresponding energy Atom UConn Mentor Connection 2010, Mariel Tader

  6. Coherent Bremsstrahlung • Requirements: • Must be in a crystal • Particle/crystal must be in correct alignment • A few specific wavelengths are prevalent, “peaks” UConn Mentor Connection 2010, Mariel Tader

  7. Reciprocal Lattice Vectors • Bravais Lattice: repeating crystalline arrangements of points • Reciprocal Lattice: made from the vectors perpendicular to three of the vectors of the original lattice • Used as a simple geometric model that can interpret diffraction in crystals UConn Mentor Connection 2010, Mariel Tader

  8. Thank You for Listening • Questions? • Interesting Facts: • Within the detector’s first year, it will collect more data than all existing data of this type by several orders of magnitude • The forces along the gluon flux tube are about 16 tons UConn Mentor Connection 2010, Mariel Tader
