摘要： In a structure or device having a pair of electrical conductors separated by an insulator across which a voltage is placed, resistive layers are formed around the conductors to force the electric potential within the insulator to distribute more uniformly so as to decrease or eliminate electric field enhancement at the conductor edges. This is done by utilizing the properties of resistive layers to allow the voltage on the electrode to diffuse outwards, reducing the field stress at the conductor edge. Preferably, the resistive layer has a tapered resistivity, with a lower resistivity adjacent to the conductor and a higher resistivity away from the conductor. Generally, a resistive path across the insulator is provided, preferably by providing a resistive region in the bulk of the insulator, with the resistive layer extending over the resistive region.

摘要： A system and method for producing modulated electrical signals. The system uses a variable resistor having a photoconductive wide bandgap semiconductor material construction whose conduction response to changes in amplitude of incident radiation is substantially linear throughout a non-saturation region to enable operation in non-avalanche mode. The system also includes a modulated radiation source, such as a modulated laser, for producing amplitude-modulated radiation with which to direct upon the variable resistor and modulate its conduction response. A voltage source and an output port, are both operably connected to the variable resistor so that an electrical signal may be produced at the output port by way of the variable resistor, either generated by activation of the variable resistor or propagating through the variable resistor. In this manner, the electrical signal is modulated by the variable resistor so as to have a waveform substantially similar to the amplitude-modulated radiation.

摘要： A charged particle beam transport system and method for linear accelerators includes a lens stack having two electrodes serially arranged along an acceleration axis between a charged particle source, and a linear accelerator. After producing and extracting a bunch of charged particles (i.e. particle beam) from the particle source, a voltage difference between the two electrodes is ramped in time to longitudinally compress the particle beam to be shorter than the pulsewidth of acceleration pulses produced in the accelerator. Additional electrodes may be provided in the lens stack for performing transverse focusing of the charged particle bunch and controlling a final beam spot size independent of the current and energy of the particle beam. In a traveling wave accelerator embodiment having a plurality of independently switchable pulse-forming lines, beam transport can also be controlled by triggering multiple adjacent lines simultaneously so that the physical size of the accelerating electric field is longer than the charged particle bunch, as well as by controlling trigger timing of the pulse-forming lines to perform alternating phase focusing.

摘要： A dielectric-wall linear accelerator is improved by a high-voltage, fast rise-time switch that includes a pair of electrodes between which are laminated alternating layers of isolated conductors and insulators. A high voltage is placed between the electrodes sufficient to stress the voltage breakdown of the insulator on command. A light trigger, such as a laser, is focused along at least one line along the edge surface of the laminated alternating layers of isolated conductors and insulators extending between the electrodes. The laser is energized to initiate a surface breakdown by a fluence of photons, thus causing the electrical switch to close very promptly. Such insulators and lasers are incorporated in a dielectric wall linear accelerator with Blumlein modules, and phasing is controlled by adjusting the length of fiber optic cables that carry the laser light to the insulator surface.
