Embodiment Construction

[0058] figure 1 and figure 2 An example of a capsule for transferring target material 2 according to the invention is shown for use in a transport system between a target irradiation station and a collection station, such as a hot cell.

[0059] The capsule includes:

[0060] - a beam channel 4 extending along the beam channel axis X1 for passing the energy beam irradiating said target material 2,

[0061] - a target holder 1 for holding a target material 2 or a substrate 2a backed by a target material 2 at a grazing angle relative to said beam path axis X1,

[0062] - a housing 3 for enclosing said target holder 1, said housing 3 being openable so that when the housing 3 is opened, the target material 2 can be inserted into or removed from the target holder remove,

[0063] - at least one energy-reducing foil 5a, 5b, 5c positioned across the beamline channel 4 for reducing the energy of the energy beam upstream of the target material 2,

[0064] - at least one target co...

Abstract

A capsule for the transfer of a target material (2) in a conveying system between a target irradiation station and a collecting station, such as a hot cell comprises: a beamline channel (4) for the passage of an energetic beam irradiating said target material (2), a target holder (1) for holding the target material (2) or a substrate backing the target material (2), a housing (3) for enclosing said target holder (1), said housing being openable such that the target material (2) can be inserted in or removed from the target holder (1) when the housing (3) is opened, a degrader foil (5a, 5b, 5c), said degrader foil being positioned across the beamline channel (4), at least one target cooling inlet (14) and one target cooling outlet (15), and at least one degrader foil cooling inlet (20) andone degrader foil cooling outlet (21).

Description

technical field [0001] The invention relates to a system for transferring target material between a target irradiation station, where the target material is irradiated with an energy beam, such as a particle beam, and a collection facility, such as for the production of radionuclides In the thermal chamber of the system, the irradiated target material is collected. Background technique [0002] Irradiating a target material with an energy beam is used in many modern applications. For example, for medical applications, radionuclides have long been produced by cyclotron irradiation of target materials with medium or low energy (5-30 MeV) beams. Radionuclides have many important industrial and scientific uses, the most important of which are tracers: radiopharmaceuticals are synthesized by reaction with appropriate non-radioactive precursors and, when administered in the human body, allow the passage of positrons Emission tomography (PET) for diagnosis and therapy monitoring,...
