Electron beam treatment for invasive pests
A system and method for the treatment of invasive pests includes an irradiation device that can generate an electron beam that is applicable to a tree infected by an invasive pest, wherein the electron beam provides an in-situ treatment for the tree infected by the invasive pest by killing the invasive pest via electron beam irradiation. One or more temperature sensors can be used to track the internal temperature of a tree surrogate. A differential temperature difference tracked by temperature sensor can be used to ensure that a reduction in temperature of the tree is attributable to the electron beam rather than increase in heat.
