TULIP is a new Target and Ion Source System (TISS) for SPIRAL1. It aims to produce neutron deficient short-lived isotopes in the area of 100Sn using the fusion-evaporation production mechanism. The first step of the project is a surface ionization TISS in order to validate key aspect of the design. The second step is the production of metallic element using electron impact ionization. One of the key aspect of an ISOL system is its atom-to-ion transformation time, as a faster TISS allow the production of isotopes with shorter half-life.
The surface ionization version is the subject of this talk. It has been successfully tested on-line in march 2022. Rubidium 76 and 78 were observed. Atom-to-ion transformation time measurement has been carried out with a groundbreaking result of less than 400µs, 2 orders of magnitude shorter than the ones generally observed with the other ISOL production systems.
