This paper focuses on the design and analysis of RF MEMS metal contact switch with a π shaped cantilever beam operating in the frequency range from 4 to 12 GHz. The topology of the design is a modified cantilever beam to achieve a low pull-in voltage. The design was analyzed as a metal contact switch to ensure its operation from DC onwards. The design is modified in terms of thickness of the beam,...
Ongoing experiments on the National Spherical Torus Experiment have demonstrated ohmic transformer flux savings by initiating the discharge with transient coaxial helicity injection (CHI). The combined use of discharge cleaning of the CHI electrodes and use of lithium evaporation, along with the use of poloidal field coils, to produce a buffer flux that prevents arcs at the top of the device has been...
