An apparatus for delivering a beam of charged particles along two separate beam paths comprising a pulsed charged particle beam source for producing a series of beam pulses along a first beam path, a switching magnet for developing a magnetic field, and a power supply means for selectively applying current pulses to said switching magnet in timed relation to each of a plurality of predetermined beam pulses effective to develop a constant magnetic field throughout the period of each predetermined beam pulse and deflect each entire predetermined beam pulse from said first beam path to a second beam path.

Simultaneous double sided irradiation

An electron beam stop for use with high power electron beam accelerators can be used to measure beam parameters including energy, current, scan width, scan offset and scan uniformity. The beam stop is split in two segments in the direction of electron travel, with the first segment closest to the beam source absorbing a portion of the electrons incident thereon and the second segment farthest from the beam source absorbing all of the electrons that pass through the first segment. The ratio of charges deposited in the two segments is a sensitive index of the energy of the primary electrons, i.e., a measure of beam energy. The sum of the charges in the two segments is a direct measure of the number of electrons incident on the absorbing medium, i.e., a measure of the beam current.

Electron beam stop analyzer

Absorbed dose in a product being irradiated by an electron beam is determined by measuring the collectable current in a beam stop and correlating the current to absorbed dose.
