Magnetic field generation in ICF target corona and its effect on hot electron generation by the two-plasmon-decay instability*

The large amplitude (>10 T) and long scale length (>10μm) magnetic field observed in the coronal plasma of inertial confinement targets can be generated from the Rayleigh-Taylor instability and further amplified by the magneto-thermal instability (MTI). We will discuss the range of the magnetic field strengths that can be amplified by MTI. Particle-in-Cell simulations show that B field on the order of 100T would not affect linear growth of the two-plasmon-decay instability but can significantly reduce hot electron generation by interrupting the staged acceleration process
