Low-frequency wave excitation by weak nonlinear interaction of two high-frequency pump waves: part II-experiments
This paper presents an experimental study of the characteristics of the LF wave excited in a hot magnetized plasma column by weak nonlinear interaction of two HF pump waves. These experimental features are systematically compared with theoretical ones which have been established in a previous theoretical paper.
Dipole Resonances of a Plasma in a Magnetic Field
It has been known for many years that cylindrical plasma columns subjected to a transverse electric field exhibit dipole resonance effects. Very little attention has been given to the modification of this phenomenon by a magnetic field. This paper gives a theory for the splitting of the resonance that occurs under these conditions and describes experiments carried out using mercury‐vapor discharges at a pressure of about 1 μ Hg to verify the theoretical prediction. Good agreement was obtained for magnetic fields giving an electron cyclotron frequency up to about half the geometric mean‐resonant frequency, and it is suggested that the effect provides a useful diagnostic technique for the measurement of mean electron density and magnetic field in discharge columns.
Nietzsche's Moral Philosophy
Expounds and criticizes the moral consequences of Nietzsche's basic concept of the will to power. This study argues that Nietzsche's doctrines on moral subjects reveal a man profoundly torn between different and conflicting impulses.
