PROF. DR. FELIX SPANIER
On Thursday, January 9, 2014, Prof. Dr. Felix Spanier from North West University, Potchefstrom, South Africa will give a talk on "Turbulence and charged particle transport: recent advances in numerical simulations" starting at 10:15 am in NB 7/67. He is a guest of FOR 1048.
Interested parties are welcome to attend!
Abstract: The transport of high-energy charged particles in the turbulent plasmas of the heliosphere and the interstellar medium is one of the key problems in cosmic ray physics. Understanding the transport process by means of analytical calculations by the extreme complexity of the non-linear wave-particle interaction charged particles undergo.
In the past many attempt have been undertaken to perform numerical simulations of the transport of charged particles. Most of these attempt have been using artificial turbulence. I will show now our recent model combining incompressible MHD simulations with test particle transport.
I will especially focus on the problems associated with deciphering the pitch-angle diffusion from the tracks of test particles in a turbulent plasma.
