Biographical Sketch
As a graduate student, Johan worked with the fusion-diagnostics group at the Department of Neutron Research, Uppsala University, Sweden, on a large novel neutron spectrometer at the Joint European Torus (JET) experiment at Culham Laboratories in UK. He contributed to the design, construction, and characterization of the spectrometer in the initial phase of the project, while performing experiments at JET and data analysis in the latter phase. The implementation of this novel spectrometer revolutionized neutron spectrometry for tokamak fusion plasmas.
At MIT, his research focuses on studies of inertial confinement fusion (ICF) plasmas. He is in particular involved in charged-particle and neutron spectroscopy program at the OMEGA facility at University of Rochester Laboratory for Laser Energetics. One of his contributions has been development and use of the proton temporal diagnostic (PTD) for simultaneous studies of the D3He- and DD-burn history. The PTD was implemented at OMEGA in the fall of 2002, and the first measurements were subsequently performed in December the same year. The PTD data significantly improved our understanding of implosion dynamics, which rendered him an invivation to talk about these new results at the annual meeting of the American Physical Society Division of Plasma Physics in Albuquerque, 2003. In addition to his own research activities, he mentors several graduate and undergraduate students. He has led the rebuilding, assembling and operating of the MIT accelerator/fusion product generator, which is used for education and for ICF diagnostic development. In addition, Johan is leading the design and construction of a novel neutron spectrometer for measurements of down-scattered neutrons, at both OMEGA and the NIF, from which rhoR in the 100 to 2000 mg/cm2 can be inferred. The spectrometer is a Magnetic Recoil Spectrometer (MRS) that covers the energy range 6 to 32 MeV, enabling simultaneous measurements of down-scattered, primary and tertiary neutrons. The OMEGA spectrometer is scheduled to be up and running in July 2007, the NIF spectrometer a few years later. Since the NIF facility requires a paradigm shift in the approach to certain diagnostics (the planned maximum yield is about 1e+19 neutrons, compared to 1e+14 neutrons at OMEGA), Johan is also involved in the multi-lab team effort in defining the diagnostic suite for the ignition experiments at the NIF, which is an effort based on the identification of physics quantities of interest.
