Description

The On-Line Isotope Separation (ISOL) method is used at ISOLDE for the production of intense radioactive ion beams of 70 different chemical elements with the best possible beam purity. Within EURISOL, direct targets are expected to operate for at least 3 weeks at 100kW of primary proton beam power. To fabricate such targets many issues have to be addressed, which includes the ones related to diffusion in the target, effusion at the surface, heat removal, temperature distribution, ageing and an efficient target and ion-source combination to form a selective system. This presentation will be focused on the development of a new SiC target. Off-line release studies were done at ISOLDE using Rabit (Rapid p-Beam Irradiation Transport) and ion-implantation techniques to estimate the diffusion coefficient of selected isotopes. Online tests were then performed with the best target material candidate. I will finally briefly introduce the ongoing TARPIPE experiment within EURISOL DS, which aims the investigation of the target’s ageing at high temperature under proton irradiation, which starts at PSI in spring 2007.
