NEGATIVE MASS INSTABILITY IN LOW VOLTAGE CYCLOTRON RESONANCE MASER

The Gyrotron, most powerful CRM, is an extremely effective device used to generate high power microwave radiation. It is used in microwave heating of thermonuclear plasma, RADAR and other industrial applications. However, the Gyrotron requires very high voltages to produce, and in turn, relativistic electrons produce intense and dangerous X-rays. In this paper, we discuss an alternate method of operation that does not require high voltages. We have also constructed a low voltage Cyclotron Resonance Maser (CRM) that operates at 2100 Volts, produces 8 GHz at a magnetic field of 0,3 T. In principle, the device should operate at even lower voltages.
