    Abstract: A klystron tube for amplifying signals at microwave radio frequencies utilizes an electron source for emitting electrons through a field focused by a high energy magnet in the RF section of the tube. After the electrons have passed through the active area of the tube, the electrons strike the collector which, in this case, is a multistage depressed collector. The multistages of the depressed collector are connected to high energy voltage sources of different potentials. The klystron tube with the multistage depressed collector is uniquely used here for the first time in a ground based satellite or terrestrial communications system.

    Abstract: According to the present invention, there is provided a compact source of intense THz radiation comprising a short bunch, low energy particle beam source, an accelerator cavity and an electromagnetic wiggler. Application of state-of-the-art superconducting accelerating structures and beam recirculation allows such a THz radiation source to have a small footprint and high average intensity without the need of the larger equipment necessary to produce the large charge per bunch generally associated with the production of THz radiation. Consequently, low emittance electron beams can be used to produce emitted THz radiation of high average brilliance.

    Abstract: In a field emission cathode emitting an electron beam modulated by any desired high frequency, a cathode tip is formed in one surface of an N type semiconductor substrate constituting a collector region, an insulating layer formed on the one surface of the semiconductor substrate to have an opening which surrounds said cathode tip, a gate electrode is formed on the insulating layer to have an opening which surrounds the cathode tip, a P type base region is formed in the other surface of the semiconductor substrate, a base electrode is formed on the base region, an N type emitter region is formed in the base region, and an emitter electrode is formed on the emitter region. A DC supply source is connected across the gate electrode and the emitter electrode and a high frequency supply source is connected across the base electrode and the emitter electrode. Then, an electron beam modulated by a high frequency within the millimeter wave or microwave region of the high frequency supply source can be emitted efficiently from said cathode tip. Additionally, an electron beam modulated at a high frequency is generated by applying the Gunn effect in a compound semiconductor to a field emission cathode. The thus generated electron beam is cooperated with a cavity resonator or Fabry-Pérot resonator, and an electromagnetic wave within the millimeter wave or microwave region can be efficiently generated.

    Abstract: An anode control circuit for at least two traveling wave tubes powered by a common electronic power conditioner. The anode control circuit has separate anode drive circuits for the traveling wave tubes that are referenced to a voltage that is higher than the cathode voltage being supplied by the electronic power conditioner. A relay between the anode drive circuit and the anode of the traveling wave tube being driven opens or closes a path between the traveling wave tube and the cathode voltage supplied by the electronic power conditioner. The anode drive circuits are referenced to one of the collector voltages that is closest to the anode operating voltage and such that the anode voltage is more positive than the reference voltage.

    Abstract: A toroidal magnet structure for polarizing a magnetic wiggler and a synchrotron normal is provided. This structure comprises a toroid composed of a plurality of magic ring semicircular segments, with an equatorial slot extending about a periphery of the toroid. The toroid further comprises a central hollow core and a toroidal axis perpendicular to the toroid. The magic ring semicircular segments are wedge-shaped to prevent magnetic flux leakage between segments and to form a continuous toroid. The equatorial slot allows emission of radiation outside the toroid. An electron beam means injects an electron beam into the central hollow core. The magnetic field thus created has a vertical component Bv within the central hollow core and a periodic horizontal component Bh, alternating in direction from ring to ring. The vertical component Bv keeps the electron beam in a generally circular electron path around the toroid and is constant along the entire path. The periodic horizontal component Bh alternates in direction and, due to its periodicity, results in a vertical oscillation of the electron beam thereby giving rise to the wiggler radiation that is polarized vertically.
