Electron Beam Accelerator : Accelerator works
on the same principle as a television tube. Electrons are generated
by a heated filament, which forms the electron gun. A voltage gradient
draws the electrons away from the gun and accelerates them through
the vacuum tube. As the high voltage beam of electrons passes from
the beam tube and through the scan magnet, an oscillating magnetic
field sweeps the beam back and forth across the scan window.

| The Real Difference : Where the objective
of a television is to create the picture, an Accelerator bundles electrons
into a 3 to 5 cm diameter beam to irradiate industrial products. The
enormous number of electrons and the high acceleration voltage produces
rapid reactions by operating directly on the molecules of the Polymers.
E.B. Gross-linking is caused by interaction of high-energy electrons
with the polymeric material and results in a three-dimensional network
structure. Through this transformation the thermal and mechanical
properties are improved while its electrical properties remain unchanged. |
