Electron processors accelerators

Figure 46.20 shows a schematic of an electron processor. The electron processor is a stainless steel vacuum tube in which one or more longitudinal heated-filament electron guns are raised to a potential of several kilovolts. The electrons are then accelerated as they move from the filaments to the perimeter of the tube. A slot in the tube defining the width of the processing zone permits the accelerated electrons to reach a metallic foil window that is thin at ground potential. 

The basic electrical parameters of an electron beam processor are its acceleration voltage, the electron beam current, and the electron beam power. The ratio of electron beam power and the input electrical power defines the efficiency of an electron accelerator. The acceleration voltage determines the energy of the electrons, as pointed out in Section 2.2. 

X-ray Machine Sterilizers, Processors, and Particle Accelerators X-rays, protons, deuterons, electrons, gammas, Cesium-13 7, Cobalt-60 4 TBq to 40PBq Anywhere in an industrial area. Be aware of possible activation products. 

The depth of electron penetration depends on the density of the material. ThuS/ the penetration ability of the processor is quoted as thickness of unit density product or weight per unit area / e.g./ gram per square meter or pound per ream (1 lb/ream=1.6 g/m ). The relationship between the electron dose (% front surface) versus penetration is shown in Fig. 5. The only way to increase the penetration depth is to increase the accelerating voltage.
