Materials science (microelectronics analysis, surface layers, multilayers, PIXE channeling of dopants in crystals, depth profiling, binary alloys, impurities deposited in nuclear fusion devices, magnetic relaxation in nanocrystalline iron, insulating materials, radiation-induced segregation, superconductors, catalysts, and diffusion studies). 

Pulsed plasmas containing hydrogen isotopes can produce bursts of alpha particles and neutrons as a consequence of nuclear reactions. The neutrons are useful for radiation-effects testing and for other materials research. A dense plasma focus filled with deuterium at low pressure has produced 10 neutrons in a single pulse (76) (see Deuterium AND TRITIUM). Intense neutron fluxes also are expected from thermonuclear fusion research devices employing either magnetic or inertial confinement. 

There is good reason to be enthusiastic about these materials. Because liquid nitrogen is quite cheap (a liter of liquid nitrogen costs less than a liter of milk), we can envision electrical power being transmitted over hundreds of miles with no loss of energy. The levitation effect can be used to construct fast, quiet trains that glide over (but are not in contact with) the tracks. Superconductors can also be used to build superfast computers, called supercomputers, whose speeds are limited by how fast electric current flows. Furthermore, the enormous magnetic fields that can be created in superconductors will result in more powerful particle accelerators, efficient devices for nuclear fusion, and...
