Accelerators for E-beam and X-ray processing

Tailoring the characteristics of organic semiconductors including molecular semiconductor and conducting polymers is the frontline area of research for improving the performance of organic electronic devices. Electron beam treatment has been established as one of the easiest method in comparison to others like chemical doping, thermal processing, ozonolysis, UV and other ionizing radiation treatment, to tune the physico-chemical properties of organic semiconductors. High energy electron beam (EB) generated from an accelerators impinges energy to the material and causes several phenomena including doping, crosslinking, chain degradation, gas evolution, molecular structural modifications, oxidation and unsaturation. Such modifications lead to variation in electrical characteristics and consequently affect the overall device performances. In the present review we have focused on the different interaction processes of EB with organic semiconductors and its implications to tailor the performance of device comprising of it mainly gas sensors, field effect transistors, thermoelectric power generators and radiation dosimeters.

Two types of radio-frequency electron accelerators are described in this article. They operate in the frequency range of 100-200 MHz and are energized with triode or tetrode tubes instead of klystrons. They can provide more powerful electron beams than typical microwave linear accelerators. Keywords: ILU accelerators; Rhodotron accelerators; electron beam processing; X-ray processing. 213 Rev.

“…In recent years, the impact of ionizing radiation fluxes has been developed in the production and modification of materials. In this case, the fundamental phenomenon of a multiple increase in the process of synthesis of multicomponent powder materials [5][6][7][8][9][10][11][12][13] and sintering [14][15][16][17][18][19][20][21][22][23][24] under radiation-thermal (RT) conditions was discovered. The processes of lithium-titanium ferrites sintering have been most fully studied under such specific conditions of the combined action of high temperatures and intense electron flows [25][26][27][28][29].…”

The measuring the temperature dependence of the initial permeability was used to study the features of phase and structural transformations in lithium-titanium ferrites as a function of time, heating and cooling rates, and the temperature of liquid-phase sintering under thermal and radiation-thermal heating. Ferrite was synthesized from powder mixture by solid-phase synthesis. A low-melting additive bismuth dioxide was used to obtain the ferrite ceramics by liquid-phase sintering. RT sintering was carried out by heating the samples with a pulsed (1.5–2.0) MeV electron beam. It was established that the additive leads to a less defective state of sintered ferrites, while the action of radiation enhances this effect in the early stages of sintering. The regularities of the influence of the heating and cooling rates of compacted samples on the change in the initial magnetic permeability of sintered ferrites are established.
