Quick Shot

Over the past decade, scientists at MIT and LLE have developed a number of magnet-based, charged-particle spectrometers for the OMEGA laser. These spectrometers have contributed significantly to the fusion mission of the Laboratory and have been used for precise measurement of neutron-scattering cross sections (this work was published a few years ago in Physical Review Letters by J. Frenje et al.). A new diagnostic was recently developed to meet measurement requirements for experiments on the National Ignition Facility (NIF). The magnet-based particle time-of-flight (MagPTOF) diagnostic will measure the shock and compression bang times on a variety of implosion platforms. Hong Sio, an MIT graduate student, is planning to use data from this instrument for his Ph.D thesis. Shown is senior manufacturing engineer John Szczepanski with the assembled unit. Also shown is the project team consisting of Milt Shoup, John Szczepanski, Johan Frenje (MIT), Mark Bedzyk, Jason Magoon, and Tony Agliata (group), and MIT graduate students Hans Rinderknecht and Hong Sio (below).
