Description
The HIE-ISOLDE project is the upgrade of the existing facility ISOLDE, which is dedicated to the production of a large variety of radioactive ion beams for many different experiments.
Among other things, HIE-ISOLDE project requires the production of many accelerating superconducting cavities in order to increase the speed and the energy of the beam. These superconducting cavities are made of a Copper substrate, in top of which is deposited a thin micrometric layer of a superconducting material, in our case Niobium.
In a first phase, the goals are to obtain good-quality Nb/Cu films - which is already a challenging task in such a complex geometry - and also to ensure reproducibility. This requires an in depth knowledge of thin film and ultra-high vacuum (UHV) technology. This activity is still ongoing.
In a second phase, the aim will consist of the “industrialization” of the HIE-ISOLDE cavities, meaning to carry out the production of the required number of cavities guaranteeing their quality and functionality.
