Magnetic diversion of laser ablation plumes

ABSTRACT:

Following each IFE target explosion, the chamber walls are bombarded by a large flux of photons (gamma & x-rays), energetic ions, and neutrons. MeV alpha particles threaten the survival and lifetime of dry chamber walls. Static magnetic fields have been proposed as a potential means to divert or stagnate the energy from the rapidly expanding plasma. Recent photographic and spectrographic results indicate successful confinement of a laser produced plasma plume in the presence of a transverse magnetic field.
