Title: Initial results from the RHEPP module

Abstract

Pulsed discharges can be used to ionize the stack gas to provide the free radicals needed to react chemically with the pollutants. To accomplish this goal over a significant fraction of the volume without heating the bulk of the gas, high voltage, short pulses are applied to the discharge electrodes. These parameters can not be readily achieved with standard pulse generators using thyratrons or hard tubes as switches. Pulse generators based on spark gaps are, planned for the pilot plants but are not likely to have the lifetime required for industrial applications. A technology is required that will provide these >200-kV, <500-ns, 4-M average power pulses and operate reliably for many years without major component replacement. The goal of the Repetitive High Energy Pulsed Power (RHEPP) program is to develop the design techniques, the long life components, and the system architecture that will provide the basis for creating these pulse generators. Our approach is based on the use of saturable reactors in Melville pulse compression networks (Melville 1951). The final L-C stages are arranged as a pulse forming network to produce the required pulse shape. Pulsed electron beams can also be used to ionize stack gases utilizing injected. Our goalmore » during 1993 is to demonstrate the 1-MeV, 160-kW average power, electron-beam accelerator operation and to begin testing of the 2.5-MeV, 350-kW average power, second generation electron beam accelerator. With these accelerators we will establish the reliability of components and systems that could be produced to meet any of the above application requirements. This report describes the approach and progress that we have made towards our goals.« less
