System for production of radioisotopes by bremsstrahlung comprising a curved converter

A method for producing a radioisotope wherein a system for producing the radioisotope includes:

• an electron accelerator configured to generate an electron beam of accelerated electrons along an irradiation axis, a scanner configured to diverge the electron beam along a scanning pattern to form a scanned beam, a focuser including one or more magnets configured to focus the scanned beam over an irradiation plane converging towards a focusing point located on the irradiation axis, to form a focused beam, the irradiation plane being defined by the irradiation axis and a transverse axis, the transverse axis being perpendicular to the irradiation axis, a converting unit located between the focuser and the focusing point and having one or more bremsstrahlung converters, the converting unit configured to convert the focused beam into a photon beam, each of the one or more bremsstrahlung converters being curved such that the focused beam intersects the one or more bremsstrahlung converters with an intersecting angle between 65° and 115° at a plurality of points, a converter cooling system configured to cool the one or more bremsstrahlung converters, and a target holder configured for holding a target, the electron accelerator, the scanner, the focuser, the converting unit, and the target holder being aligned along the irradiation axis and arranged in sequence along a direction of the electron beam, the method comprising:
• loading the target onto the target holder;
• scanning and focusing an accelerated electron beam onto the converting unit;
• converting, by the converting unit, the electron beam to produce X-ray;
• and
• irradiating the target with the X-ray to produce the radioisotope.
