Solid targetry at the TESLA Accelerator Installation

摘要

According to the concept of the TESLA Accelerator Installation, the channel for production of radioisotopes has to routinely produce Tl-201, In-111, Ga-67, I-123 and F-18, and a number of other radionuclides for experimental purposes. The production of I-123 and F-18 will be performed in dedicated, commercial target stations, while a versatile solid target irradiation system is designed for the routine and experimental production of all other radioisotopes. The solid target station is designed to accept targets for both the 7degrees and 90degrees irradiation geometry. The targets used for the routine production will be prepared by electroplating on a silver substrate. They can be irradiated with a 1.5 kW beam using the 7degrees geometry. The cooling of these targets is enhanced by fins on the back of the silver substrate designed so that the highest temperature on the surface of the target does not exceed 110degreesC. The irradiation procedures will conform to the GMP requirements for the production of radio pharmaceuticals. The irradiated targets will be transported directly into the appropriate hot cell for radiochemical processing, All cells will be equipped with a target dissolution unit for etching the irradiated, electroplated film. After decontamination and sufficient cooling down, these targets will be reused several times. (C) 2001 Elsevier Science B.V. All rights reserved. References: 9
