The TULIP project* aims to produce radioactive ion beams of short-lived neutron-deficient isotopes by using fusion-evaporation reactions in an optimized Target Ion Source System (TISS). The first step consists of the design of a TISS to produce rubidium isotopes. It was tested with a primary beam of 22Ne@4.5 MeV/A irradiating a natNi target at the SPIRAL1/GANIL facility in March 2022. Rates of 76,78Rb were measured as well as an exceptionally short atom-to-ion transformation time for an ISOL system, of the order of 200 µs.
The second step of the project aims at producing neutron deficient short-lived metallic isotopes in the region of 100Sn. A “cold” prototype has been realized to study the electron impact ionization in the TISS cavity and a “hot” version is under construction to prepare an on-line experiment expected in 2023.
Obtained results and the project status will be presented.
