Plasma Physics Seminar
“Electron Transport in Plasmas” by Professor Amita Das, Institute for Plasma Research, Gujarat, India
Abstract: The electron beam transport and its energy deposition in plasma is crucial in the context of many applications such as fast ignition etc., where it is desirable to dump energy in an overdense compressed core of the target where lasers are unable to penetrate. The talk will cover complex collective physics associated with electron beam plasma instabilities, the associated evolution of magnetic fields and the ensuing turbulence leading to possible anomalous behavior of transport. The experimental evidences in support of anomalous transport will be provided. A novel effect arising due to finite transverse beam size will also be demonstrated.
