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 plurality of redirector magnets having a magnetic field for steering electrons to an output of the horn;
- a first detector unit comprising a center detector and side detector, the center detector and the side detector 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.

An irradiation system, comprising:
- a conveyor system having a conveyor belt with rollers having a space between the rollers that allow a passage of an electron field created from an electron beam through the space between the rollers of the conveyor belt;
- and
- a first horn comprising:
- a portion for receiving electrons;
- a plurality of redirector magnets having a magnetic field for steering the electrons to the output of the first horn;
- a first detector unit for detecting a dosage 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.
