Embodiment Construction

[0047] Systems, devices, and methods for producing radioisotopes are disclosed herein. The disclosed systems may include devices operable to maintain irradiation of one or more targets while also operable to direct coolant through the targets and other portions of the device that may be heated by the irradiation. Exemplary devices disclosed herein may include an elongated housing, a target holder, one or more curved windows, and one or more targets. The target is held in a desired orientation by a target holder within the housing such that the applied radiation passes through the curved window and into or through the target to produce the desired radioisotope in the target. A target may comprise any number of individual target elements, eg disks or spheres, arranged in a specific manner to interact with the applied radiation. The housing is also configured to direct coolant through the target holder, over the target, and / or at least through the inner surface of the curved win...

Abstract

An apparatus for radioisotope production includes a housing, a plurality of target disks within the housing, and a curved window positioned to project inwardly toward the disks. During operation, the coolant flows through the housing, across the disks and windows, while the electron beam passes through the windows and disks. The window temperature increases, most rapidly in the middle of the window where the electron beam strikes the window. A flat window will buckle because the center will deform during thermal expansion of the relatively unaffected perimeter, but the curved window shape allows the window to withstand the high heat and mechanical stress. Such windows can be used in applications where the pressurized coolant acts on only one side of the window.
