摘要： Microwave energy is coupled into an elongate waveguide having a rectangularain cavity with a lateral branch forming a T section. An intense beam of electrons is generated in the rectangular cavity at a particular location relative to the T to reflect incident microwave energy and produce a standing wave. Quarter wavelength spacing of the beam from the T positions either a wave node or antinode at the T. Preferably, in its `open` state, accumulated microwave energy is released as a high power output pulse by establishing an antinode at the T. Alternatively, a node at the T produces a normally `closed` state. In all arrangements, the beam of electrons, which traverses the central portion of the narrow dimension of the rectangular cavity in a direction parallel to the electrical field of its microwave energy, is of sufficient electron density to assure the desired reflection and produce the interference pattern.

摘要： High power, phase coherent pulses are generated by superconducting appara which includes a superconducting cavity resonator that is pumped by a low power microwave source while being isolated from a load. Switching of the cavity to an emitting mode is accomplished in 5 to 10 nanoseconds by firing a gas discharge tube that acts to couple the activity to the load while decoupling it from the pumping source.

摘要： A high energy photon source. A pair of plasma pinch electrodes are located in a vacuum chamber. The chamber contains a working gas which includes a noble buffer gas and an active gas chosen to provide a desired spectral line. A pulse power source provides electrical pulses at repetition rates of 1000 Hz or greater and at voltages high enough to create electrical discharges between the electrodes to produce very high temperature, high density plasma pinches in the working gas providing radiation at the spectral line of the source or active gas. A fourth generation unit is described which produces 20 mJ, 13.5 nm pulses into 2 &pgr; steradians at repetition rates of 2000 Hz with xenon as the active gas. This unit includes a pulse power system having a resonant charger charging a charging capacitor bank, and a magnetic compression circuit comprising a pulse transformer for generating the high voltage electrical pulses at repetition rates of 2000 Hz or greater.

摘要： A high energy photon source. A pair of plasma pinch electrodes are located in a vacuum chamber. A working gas which includes a noble buffer gas and an active gas chosen to provide a desired spectral line. A pulse power source provides electrical pulses at voltages high enough to create electrical discharge between the electrodes to produce very high temperature, high density plasma pinch in the working gas providing radiation at the spectral line of the active gas. An external reflection radiation collector-director collects radiation produced in the plasma pinches and directs the radiation in a desired direction. In a preferred embodiment the active gas is lithium and the buffer gas is helium and the radiation collector-director is coated with the material used for the electrodes. A good choice for the material is tungsten. In a second preferred embodiment the buffer gas is argon and lithium gas is produced by vaporization of solid or liquid lithium located in a hole along the axis of the central electrode of a coaxial electrode configuration. Other preferred embodiments utilize a conical nested debris collector upstream of the radiation collector-director.

摘要： An improved method and apparatus for generating a pulsed RF power signal is provided. A DC pulse signal is generated which is compressed to increase its power to a predetermined level. The compressed pulse signal is applied to rapidly charge capacitive elements of a frozen wave generator. The capacitive elements may for example be lumped capacitors or transmission line segments. The charging step is accomplished in a manner such that the level and/or polarity of the charge for alternate stages are different than the level and/or polarity for the remaining stages. This may be accomplished by initially charging all stages to the same level and polarity and then either flipping the charge for alternate stages or otherwise altering the charge for such alternate stages or by initially charging alternate ones of the stages to a different level and/or polarity than the remaining stages. Once the capacitive elements for all stages of the frozen wave generator are charged to the desired level and/or polarity, the charges are permitted to propagate through the frozen wave generator to the last stage thereof, the desired RF output signal being taken at the output from such last stage.
