TARGET RECOVERY AND COOLING APPARATUS FOR PRODUCING RADIOACTIVE ISOTOPE

摘要

PURPOSE: A target recovery and cooling apparatus for producing a radioactive isotope is provided to generate a radioactive isotope easily by the usage of a fluid target such as a liquid or a gas. CONSTITUTION: In a target recovery and cooling apparatus for producing a radioactive isotope, a supplying container(2) supplies a fluid target, and syringe pump(3) takes a fluid target of a constant amount from the supplying container to send the taken fluid target to the next stage. A six-port valve(4) is connected to the syringe pump, and outputs a fluid in the predetermined direction. A target chamber(TC) is supplied with the fluid target from the six-port valve, and generates a radioactive isotope when a proton beam is incident to the fluid target. A helium container(5) is connected to the target chamber, and pushes the fluid target incorporating the radioactive isotope to the six-port valve. A recovery container(6) is connected to the helium container, and extracts the radioactive isotope from the fluid target to recover the fluid target. A cooling part(7) is installed at the front part of the target chamber, and cools a heat generated at the target chamber.
