Abstract
The Orbitron MASER is a negative mass unstable device, which can be used to produce millimeter and submillimeter RF radiation. In its basic design, the Orbitron is a coaxial structure with a high positive potential between the outer cathode and inner anode wire. Electrons are supplied to this system by either an internal glow discharge or by an oxide coated hot electron emitter. These electrons, due to an initial angular velocity, go into orbit around the positive central wire and emit a frequency that is inversely proportional to the radius of their orbits. Emission, from the pulsed form of this device, has been observed at a frequency of 1 THz.
