Behavior of phosphine in a focused CO2 laser beam
The energy absorption and decomposition of PH3 in a focused CO2 laser beam exhibit a threshold nature. The effect of laser frequency, pulse energy, pressure of PH3, and the presence of a foreign gas (...

Three-dimensional codes for calculations of a stray magnetic field of iron core of a toroidal plasma confinement system have been developed. The calculated results agree well with the measured ones. It is found that up-and-down asymmetry of the iron-core gap deforms the stray field asymmetrically when the primary coil current is not equal to the plasma current and that anisotropy of permeability of the iron core does not have a large influence on the field.
