The invention discloses a method for measuring atomic transverse relaxation time based on an electron resonance phase frequency analysis. In a strong-background magnetic field with almost neglected residual magnetization in a magnetic shielding barrel, a swept-frequency signal that has a bandwidth covering a resonance curve and has an amplitude enabling the resonance curve to have a clear curve under low polarizability is applied in a horizontal direction; an optical swing angle signal of a magnetometer is detected and a spectral analysis is carried out on an outputted signal in a polar coordinate system to obtain a phase frequency response function of the magnetometer; the phase frequency response function is fitted to a corresponding theoretical phase frequency curve of the magnetometer to obtain atomic spinning transverse relaxation time. Because the phase angle is a result obtained by quotient processing of a spinning transverse component, the influence of common coefficient fluctuation is suppressed, so that the phase frequency signal expression is more stable by being compared with amplitude-frequency signal expression. Besides, the theoretical phase frequency curve is not affected by the magnetic induction intensity of the transverse magnetic field and the atomic spinning longitudinal relaxation time, so that complexity of data processing can be reduced. Moreover, a lorenz curve widening risk caused by the transverse magnetic field can be eliminated.

An apparatus and method for generating a Contact Glow Plasma Discharge in an electrolyte such as 7% K2CO3. A Shrouded Toroidal Anode is partially submerged in the electrolyte directly above a Flat Torus Cathode (totally submerged in the electrolyte), spaced approximately 50 mm apart, and the two electrodes are arranged in a concentric manner. A potential difference is applied from the cathode to the anode causing gas to be formed on the cathode. This is followed by a contact glow plasma being formed on the surface of the cathode and electromagnetically confined by a Spheromark formed by the configuration of the electrodes. This confinement of the plasma prevents a plasma arc from consuming the anode, which in turn allows for the application of 12,000 Watts and the occurrence of “non-linear electron resonance heating”. The effects of nonlinear series resonance increase the total power dissipation by factors of 2-5 for low pressure capacitive plasmas. Thus explaining the 303% efficiency obtained with this apparatus.
