    摘要: A device is disclosed for simple and quick disconnection of a target assembly at a cyclotron accelerator producing an ion beam irradiating the target assembly for PET radioisotope production. The device consists of a target body presenting a target space (20) for introduction of target media to be irradiated by the ion beam from the cyclotron accelerator. The target body is separated into three portions by means of two separation window foils. The first separation window (6) separates the internal space (20) of a first body portion (2) from a further internal space portion (21) of a second target body portion (3) and the second separation window (7) separates a further internal space (21) of the second target body portion (3) from an internal space (22) of a third target body portion (4) being in communication with the vacuum space of the cyclotron. This third body portion (4) forms a bayonet fitting to a corresponding bayonet fitting (5) fixed to the cyclotron vacuum casing at a position where the ion beam is extracted, whereby the corresponding bayonet fitting also constitutes an insulating member. The device can by a small twisting be quickly released from the vacuum casing of the cyclotron after that the vacuum has been removed for necessary maintenance and service.
