F-18 RADIO ISOTOPES WATER TARGET APPARATUS FOR IMPROVING COOLING PERFORMANCE??WITH INTERNAL FLOW CHANNEL USING THERMOSIPHON

摘要

A radioactive isotope liquid targeting apparatus having a thermosiphon internal flow channel according to the present invention includes a cavity member having a cavity for accommodating a concentrate for a nuclear reaction, and produces radioactive isotopes by the nuclear reaction between protons radiated to the concentrate in the cavity and the concentrate. The cavity member comprises: a front thin film having a front opening and a rear opening that are arranged to be directed toward opposite sides to each other on a proton radiation path and are connected to the cavity so that the cavity can communicate with the outside, the front thin film being arranged to close the front opening; a front cooling member coupled to the cavity member to support the front thin film so that the front thin film may not swell by an increase of pressure in the cavity during the nuclear reaction, and arranged on the proton radiation path, and having a plurality of through-holes in a direction of the proton radiation; a thermosiphon induction member connected to the rear opening and having a thermosiphon flow channel connected to the cavity to enable the concentrate accommodated in the cavity to flow by a thermosiphon phenomenon; and a front cooling member coupled to a rear surface of the thermosiphon induction member, and having a cooling water supply space.
