• ### Design of an Energy Recovery System for a Gyrotron Backward-Wave Oscillator

Publication Year: 2009, Page(s):390 - 394

| | PDF (681 KB) | HTML

To realize the full potential of a gyrotron backward-wave oscillator (gyro-BWO), an energy recovery system was designed using Particle-In-Cell (PIC) simulations and optimized using both a genetic algorithm and PIC simulations. Simulations were carried out to optimize a periodic structure for separation of the spent electron beam and the output radiation produced by a gyro-BWO in the 8.0-9.5 GHz fr... View full abstract»

A multifrequency electron cyclotron resonance heating (ECRH) system is currently under construction at the ASDEX Upgrade tokamak experiment. The system employs depressed collector gyrotrons, step tunable in the range of 105-140 GHz, with a maximum output power of 1 MW and a pulse length of 10 s. One two-frequency GYCOM gyrotron has been in routine operation at ASDEX Upgrade since 2006. A further e... View full abstract»

In this paper, we present a detailed analysis of the iterative phase retrieval approach (IPRA) for determining the phase profile of the output microwave beam of a gyrotron from known intensity patterns emphasizing the field propagation techniques which are used to propagate the RF field of the microwave beam between known intensity planes. The propagation method, based on first Rayleigh-Sommerfeld... View full abstract»

We report the experimental results of the infrared measurements of output RF beam of the European 2-MW 170-GHz coaxial cavity gyrotron for ITER. The output beam profile is measured by the infrared thermographic technique using an infrared camera and a target material which is being irradiated by the RF output. The beam intensity was measured at several locations along the propagation direction. Th... View full abstract»

The implosion of a solid deuterium gas-puff Z-pinch was studied on the S-300 pulsed power generator [A. S. Chernenko, , Proceedings of 11th Int. Conf. on High Power Particle Beams, 154 (1996)]. The peak neutron yield above 1010 was achieved on the current level of 2 MA. The fusion neutrons were generated at about 150 ns after the current onset, i.e., during the stagnation and at ...

We report on the first investigations of the use of carbon fibers in an X-pinch load using a 250-kA linear transformer driver (LTD). Multiframe laser shadowgraphy is used to examine the evolution of the pinch and shows that carbon loads demonstrate wire expansion and cross-point pinch and gap formation as observed in X-pinches constructed from high Z materials. Radiographs taken usin... View full abstract»

The propagation velocity of light emission is observed to be up ~0.92 times10+5 m/s along a tube of an inner diameter ro ~1.5 times10-3 m with an external electrode fluorescent lamp filled with 97% Ne and 3% Ar at a total pressure of 30 torr, a mercury-free lamp without phosphor coating the inside glass wall. The origin of this propagation is shown to be... View full abstract»

• ### Analysis of the By-Products in the Ammonia Production From Urea by Dielectric Barrier Discharge

Publication Year: 2009, Page(s):444 - 448

| | PDF (238 KB) | HTML

Ammonia, which is the main product of urea decomposition, is used as the reducing agent in the gas phase plasma NOx treatment. Urea, because of its cheap price and relatively low decomposition temperature (150degC ), represents an excellent direct source of ammonia. In a dielectric barrier discharge (DBD), such temperatures can be achieved within a few minutes of applying voltage... View full abstract»

The destruction of chlorodifluoromethane (CHF2Cl) was studied in a nonthermal atmospheric pressure plasma reactor with a perforated dielectric barrier, which is capable of producing intense streamers without significant pressure drop across the reactor. The performance of the dielectric barrier discharge reactor was evaluated with the parameters including oxygen content, input power, fe... View full abstract»

We report the generation of variable plasma densities up to 1019 cm-3 in hydrogen-filled hollow cathode capillary discharges and consider their applications as a practical plasma source for particle-beam-driven plasma wakefield accelerators. The capillary consists of a transparent cylindrical borosilicate glass tube. The plasma density is determined as a function of time, usi... View full abstract»

We discuss a correction to the Green's function used to calculate the off-axis space charge limit of bunched annular electron beams in coaxial conducting structures. In addition, we discuss how the space-charge limit is affected and update our previous comparison of the experimental design parameters of the UC-Davis/SLAC 2.8-GHz coaxial ubitron oscillator with the space-charge limit.
