  • Absorption of intense microwaves and ion acoustic turbulence due to heat transport

    Lawrence Livermore National Laboratory

    Measurements and calculations of the inverse bremsstrahlung absorption of intense microwaves are presented. The isotropic component of the electron distribution becomes flat‐topped in agreement with detailed Fokker‐Planck calculations. The plasma heating is reduced due to the flat‐topped distributions in agreement with calculations. The calculations show that the heat flux at high microwave powers is very large, qmax≊0.3 NeTe. A new particle model to claculate the heat transport inhibition due…

The isotropic component of the electron distribution becomes flat‐topped in agreement with detailed Fokker‐Planck calculations. The plasma heating is reduced due to the flat‐topped distributions in agreement with calculations. The calculations show that the heat flux at high microwave powers is very large, qmax≊0.3 NeTe. A new particle model to claculate the heat transport inhibition due to ion acoustic turbulence in ICF plasmas is also presented. One‐dimensional PIC calculations of ion acoustic turbulence excited due to heat transport are presented. The 2‐D PIC code is presently being used to perform calculations of heat flux inhibition due to ion acoustic turbulence.
