  In the framework of the Spiral2 project, the PHOENIX V3 ion source upgrade has been developed to optimize the production of ion beams with charge over mass Q/A=1/3. The ion source aims to produce mainly metallic ions. For such beams, the atoms are often trapped into the plasma wall chamber leading to a poor global ionization efficiency. In order to study the wall capture and improve the atom to ion conversion, a temperature controlled liner is designed and under construction to test the atoms re-emission from the wall as a function of temperature in PHOENIX V3. In parallel, a hybrid particle in cells (PIC) code is under development to study the metallic ion dynamics in the plasma chamber and its extraction as an ion beam. A low temperature oven has been designed and tested leading to a global efficiency for Ca beam of above 20%. The oven was simulated and coupled to the hybrid PIC code to study the calcium atom capture from the oven to the plasma. Comparison between simulation and experience is proposed.
