Principles of radioisotope production with ISOL techniques, materials and ion sources

About

Abstract:

The ISOLDE radioactive isotope facility has been providing rare isotopes to users from around the world since more than 50 years, making it the oldest running experiment at CERN and is considered the mother of ISOL type facilities.

In the ISOL method, a target is irradiated with a primary beam, creating secondary radioactive isotopes which are evaporated from the target matrix, extracted as ions, purified and then delivered in form of a beam of ions to the experimental setup. The interest of the scientists requesting these isotopes ranges from fundamental nuclear structure and nuclear astrophysics, over solid state physics and semiconductor research to medical applications. At ISOLDE over 1000 different radioisotopes of the 6000 that are predicted to exist

In this lecture we will introduce how isotopes are artificially created and delivered to users at ISOLDE. We will discuss the constraints and requirements to the target materials and ion source selection, illustrated by several use cases

We will highlighting current developments towards tailor-made nano-structured target materials and ongoing target and ion source developments required to meet the demands of the user community for more exotic isotopes and purer beams.

The following two lectures will focus on selective laser photoionization used to produce purest radioisotope beams and application of radioisotopes for nuclear medicine. .
