David Nygren’s powerful particle-detection instruments are enabling breakthrough discoveries in physics and have improved practical applications such as medical imaging. Nygren developed the time projection chamber (TPC) to identify and track charged particles in complex high-energy collisions. Incorporating an intrinsically three-dimensional capability, the TPC has been implemented in particle colliders at major national research laboratories, has provided evidence of the gluon plasma state, and is playing a key role in searching for weakly interacting massive particles, in learning more about the elusive neutrino, and for many other applications. His proposal for fully depleted charge-coupled device imagers for optical astronomy are enabling a deeper view into space. Nygren’s quantum-counting mammography system enables improved image quality while greatly reducing radiation exposure.
An IEEE member, Nygren is a Presidential Distinguished Professor of Physics at the University of Texas at Arlington in Arlington, TX, USA.
