  • Pictured is the Hall C detector for the High Momentum Spectrometer (HMS). Contained in a concrete shield house, this detector is used for particle identification after the beam hits the target and the scattered particles are focused onto this detector . The detector contains several instruments that measure different elements of the particles including: drift chambers, hodoscopes, and gas and lead-glass Cerenkov detectors.

  • The Hall-C Moller Polarimeter measures the polarization of the electron beam arriving in Hall-C. It does so by observing the rate of production of Moller electrons at 90 degrees in the center of mass when the beam strikes a thin iron target. The outer shell electrons in the iron are polarized parallel (or anti-parallel) to the beam direction by a 4 Tesla magnetic field. The Moller electron production rate differs when the beam and target electron spins are aligned parallel or anti-parallel to one-another. Measurement of this rate difference provides a measure of the beam polarization.

  • Jefferson Lab staff and scientific users are exploring how artificial intelligence and machine learning can benefit ongoing scientific research and R&D.

    If you have difficulty and need an image sized properly, contact the webmaster@jlab.org about the image and what size you need. NOTE: You cannot size UP an image. It will warp and stretch the pixels. In addition to that, the image will look grainy and pixelated.
