THE HALL AND ION SLIP EFFECTS IN A NON-UNIFORM GAS
AVCO EVERETT RESEARCH LAB EVERETT MASS
Pagination or Media Count:
Under conditions that result in strong Hall or ion slip effects, a uniform and a non-uniform gas can behave much differently as conductors of electricity. An ohms law for a non-uniform gas is derived. It is used to study the performance of normal current and Hall current MHD devices and also the possibility for obtaining significant electron heating or extra thermal ionization. An indication is obtained of the degree of engineering sophistication that will be required to obtain good performance where the product of the particle mean free time between collisions and particle cyclotron frequency was high.
