Description

The LPSC ion sources team develops the Phoenix Charge Breeder since 2000. The performances have been improved over time acting on the 1$^{+}$ and N$^{+}$ beam optics, the base vacuum and the 1$^{+}$ beam injection. A new objective is to increase significantly the plasma chamber volume to improve the plasma confinement, enhance the higher charge state production and the 1$^{+}$, N$^{+}$efficiencies, and improve the ion source tunability. A development plan has been defined to modify the ion source magnetic structure accordingly with several steps in the period 2017 - 2020. The first iteration consists in increasing the axial magnetic field at injection from 1.2 T to 1.6 T by adding a plug under vacuum. It has been implemented in April 2017 and the efficiencies have been measured for gaseous and alkalis 1$^{+}$ beams. The results together with the foreseen evolution of the source will be presented.
