The TULIP project : first on-line result and near future

Abstract

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 consisted of the design of a TISS to produce rubidium isotopes. It was tested with a primary beam of ${}^{22}$[email protected] MeV/A irradiating a natural Ni target at the SPIRAL1/GANIL facility in March 2022. Rates of ${}^{76,78}$Rb were measured as well as an exceptionally short atom-to-ion transformation time for an ISOL system, of the order of 200 $\mathrm{\micro}$s. The second step of the project aims at producing neutron-deficient short-lived metallic isotopes in the region of ${}^{100}$Sn. 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 the near future.
