Magnetic Sweep of a Relativistic Electron Beam into a Rectangular Raster
- 5 Downloads
The design of a magnetic sweep unit that provides a combination of two linear (with respect to time) sweeps of the relativistic electron beam and the radiation field of the accelerated electron beam swept into a rectangular raster and scattered by an air layer when approaching the target have been considered. Expressions for the distribution of absorbed dose over the whole exposed surface have been obtained taking into account the real distribution of beam current density. The considered expressions for the distribution function of absorbed dose can be used as a foundation for the calculations of magnetic sweep units for radiochemical equipment with high-current industrial electron accelerators, in particular, with escape of a focused beam of accelerated electrons into the atmosphere.
