Observation of Simultaneous Oscillation of Multiple Modes in a CW 300 GHz Gyrotron
Multi mode oscillation was observed in a 300 GHz fully CW gyrotron. It has been developed and installed in Research Center for Development of Far-Infrared Region, University of Fukui as a power source of a submillimeter wave material processing system. This gyrotron delivers 1.75 kW / CW at maximum. The radiation pattern is a Gaussian beam when the magnetic field strength Bc at the cavity is pr...
متن کاملInfluence of reflections on the operation of the 2 MW, CW 170 GHz coaxial cavity gyrotron for ITER
The influence of reflections on the operation of the 2 MW, CW 170 GHz coaxial cavity gyrotron oscillating in the TE34,19 mode is studied. In particular, frequency-independent power reflections, e.g. from plasma or some elements of the transmission line, larger than 1% and occurring in a poor phase may lead to oscillation breakdown and should be avoided. Frequency-dependent reflections from a sp...
متن کاملDESIGN OF A 60GHz, 100 kW CW GYROTRON FOR PLASMA DIAGNOSTICS: GDS-V.01 SIMULATIONS
In this work, the design studies of a 60 GHz, 100 kW CW gyrotron have been presented. Mode selection is carefully studied with the aim of minimizing mode competition and to yield a perfect solid beam output through an RF window with a suitable dimpled-wall quasi-optical launcher. Cavity design and interaction computations are then carried out. In addition, preliminary design of the magnetron in...
متن کاملProducts of Cw-complexes
We show that Liu's characterization for the product K x L to be a CW-complex is independent of the usual axioms of set theory.
متن کاملTest of Duoplasmatron with Cold Cathode for Cw Operation
Pulse duoplasmatron with cold cathode used at preinjectors of ITEP proton linacs has been tested for generation of dc proton beam. The operation of duoplasmatron was studied experimentally with low currents of discharge. The test bench experiments allowed to modify construction of pulsed ion source for stable dc operation with high life time. The ion source generated dc beam of protons with cur...
