High power accelerators have been recently developed to meet demands of flue gas treat- ment and other high throughput processes. Such accelerators can substantially increase the capacity of the process and reduced unit cost of operation. Automatic control, reliability and reduced maintenance, adequate adoption to process conditions, suitable electron en- ergy and beam power are the basic features of modern accelerator construction. Accelera- tors have the potential to serve as big radiation sources which can transfer much higher amounts of energy into the irradiated objects than other types of facilities. That provide opportunity to construct technological lines with high capacity and they are more techni- cally and economically suitable with high throughputs and low cost what is necessary in environmental protection technologies. Some special efforts should be done to optimize electrical energy consumption for accelerator, electron beam handling system and other auxiliary equipment related to radiation facility to achieve the highest electrical effi- ciency. Electron beam technology is already being utilized in many pilot plants and dem- onstration facilities for environmental application. Several full size facilities were con- structed and implemented in different countries. Among them flue gas treatment unit equipped with four electron accelerators with total beam power over 1 MW installed in Poland. Accelerators may play a major role in new big market related to environment ap- plication of radiation processing if except high power, high efficiency, low cost they will be characterized by high reliability suitable for industrial standards. High power accelera- tor technology may need governmental support in design, construction and testing such equipment because environmental applications of EB technology are examples of high risk and not very high payoff but on the other hand radiation technology transfer to envi- ronmental application could be in result a substantial improvement in public health.

Accelerator for Producing the Ion Beams in the Continuous and Pulse Modes

The device is based on a high-voltage hydrogen ion accelerator with switching magnet (effective beam rotation angle 0±450), which works with two beam lines. Fist beam line is designed for transporting the accelerated up to 300 keV atomic hydrogen ions beam with current up to 15 mA. Second beam line designed to obtain beam pulses of nanosecond length.
