Abstract
An apparatus, system, and method for real-time dosimetry. An electron beam irradiation system includes one or more detectors. The detectors have coils that, when an electron travels by a sensor pad in the detector, the electron induces a current into the coils. The current is detected and the electron is counted. The number of electrons counted at the one or more detectors is compared to the number of electrons leaving an electron gun, giving a dosage of the workpiece being irradiated.
Claims17
A horn for use in combination with an electron gun of a radiation system, comprising:
- a portion for receiving electrons from an electron emitter;
- a plurality of redirector magnets having a magnetic field for steering the electrons to an output of the horn;
- a first detector unit comprising a center detector and a plurality of side detectors, the center detector and the plurality of side detectors each comprising:
- a top plate;
- a bottom plate;
- a sensor pad;
- and
- a copper wire coiled around a first core and a second core, wherein the coil is wound around the first core and the second core to operate as a balun.

- a top plate;
- a bottom plate;
- a sensor pad;
- and
- a copper wire coiled around a first core and a second core, wherein the coil is wound around the first core and the second core to operate as a balun.
