Title
(DE) VERFAHREN ZUR HERSTELLUNG EINES TARGETS FÜR DIE ERZEUGUNG VON RADIOAKTIVEN ISOTOPEN
(EN) PROCESS FOR PREPARING A TARGET FOR THE GENERATION OF RADIOACTIVE ISOTOPE
(FR) PROCÉDÉ DE PRÉPARATION D'UNE CIBLE POUR LA GÉNÉRATION D'ISOTOPE RADIOACTIF
Abstract
(EN) The present invention relates to a process for preparing a two-layer or three-layer target for the generation of radioactive isotopes (radionuclides) by bombardment with accelerated particles; said process comprises the coupling of the layers through the passage of an electric current (pulsed, alternating or direct) and a simultaneous application of pressure. The present invention also relates to said two-layer or three-layer target comprising a first layer and a support layer with thermal conductivity or a first layer, an intermediate layer and a support layer with thermal conductivity. Said first layer comprises an element/isotope/chemical compound and has a thickness/diameter ratio ≤ 0.25.
