SUMMARY:Investigating Dynamics of Parallel Transport in SOL Using PIC Meth
 od
DESCRIPTION:Jernej Kovacic (University of Ljubljana)\n\nIn current fusion 
 reactors the heat and particle loads from the scrape-off-layer (SOL) plasm
 a to the plasma-facing components (PFCs) are one of the main limiting fact
 ors in the process of designing devices and operational scenarios for futu
 re fusion power plants. The transport into the SOL plasma is dominated by 
 filamented structures that penetrate the last closed flux surface, the so-
 called blobs. Blobs are coherent structures of high density and high tempe
 rature plasma which travel through SOL in directions parallel and perpendi
 cular to the magnetic field. The perpendicular transport can mostly be ade
 quately described using fluid codes, but the parallel transport requires k
 inetic approach, since the parallel energy distribution function is often 
 not Maxwellian. We have used a fully-kinetic 1d3v code BIT1 to simulate a 
 flux tube in a tokamak SOL where the particle and energy source consists o
 f a series of blobs injected at the outer midplane. We have parametrically
  studied the influence of source properties on the self-consistent develop
 ment of SOL and target plasma. The simulations show significant effects of
  source temperature and blob size on the SOL particle and energy transport
