Current and charge collector as e beam energy and dose meter for industrial use

Many parameters of interest for characterizing a high power processing electron beam in air can be measured using a charge density detector system.

A rugged detector head placed in or moved through an electron beam may be used to measure the effective beam energy, current density within the beam and charge delivered to the product plane.

The liquid cooled detector may also be used to calibrate routine dosimeter for electron beam use over the full range of doses and dose rates currently used for industrial purposes.

Further uses for the detector as an accelerator control sensor element are also discussed.
