MIPSE Seminar | Active Space Experiments with Relativistic Electron Accelerators

Dr. Gian Luca Delzanno, Los Alamos National Laboratory

Gian Luca Delzanno Gian Luca Delzanno
In this talk I will discuss new space applications that are enabled by the recent development of compact, relativistic electron accelerators. First, I will describe a mission concept, called CONNection EXplorer (CONNEX), to connect magnetospheric physical processes to auroral phenomena. CONNEX is based on an electron beam fired from a magnetospheric spacecraft along magnetic field lines and optically imaging the beam spot in the ionosphere. The mitigation steps undertaken for the successful development of CONNEX will be discussed, with a particular focus on a scheme for mitigating critical issues of spacecraft charging induced by the electron beam. Second, I will discuss application of relativistic electron beams for radiation belt remediation. In this context, electron beams can excite plasma waves that can be exploited via wave-particle interaction to reduce hazardous fluxes of energetic particles to safer levels. I will also touch upon innovative numerical tools being used in support of these activities.

Gian Luca Delzanno obtained his MS in Nuclear Engr. (1999) and PhD in Plasma Physics (2003) from Politecnico di Torino (PT) in Italy. After a postdoctoral position with the Burning Plasma Research Group at PT, in 2005 he moved to the T-5 Applied Mathematics and Plasma Physics Group at Los Alamos National Laboratory, initially as a postdoctoral associate and later as a technical staff member. His research interests are in theoretical and computational plasma physics. His work addresses development of numerical methods for multi-scale plasma physics simulations with application to space-physics. The latter include the SHIELDS project to develop global space-weather models of the near-Earth environment including substorm physics, the CONNEX project to study magnetosphere-ionosphere-coupling with relativistic electron beams, and wave-particle-interaction physics.
