TI - A New Resistive High Temperature Oven for Metallic Beams Production J2 - Proc. of ECRIS2020, East Lansing, MI, USA, 28-30 September 2020 CY - East Lansing, MI, USA T2 - International Workshop on ECR Ion Sources T3 - 24 LA - english AB - For the Super Separator Spectrometer (S3) [1] currently under construction on Spiral 2 facility, metallic beams of high intensities must be delivered to impinge a target aiming to produce rare radioactive isotopes for fundamental nuclear studies. First requested beams are 58Ni, 48Ca, 50Cr, 50Ti or 50V with an intensity about 1,2.10¹³ pps. The metallic ion beams will be produced by the Phoenix V3 ECR ion source combined with a resistive oven newly designed to cope with the beam specifications. The evaporation of low vapor pressure metallic elements (Ti, V…) requires temperature within a range of 1900°C to 2000°C. A new design of a resistive oven has been developed for this purpose. The oven reached 2000°C in a test vacuum chamber during 8 days. It has worked out in the Electron Cyclotron Resonance Ion Source ECR4 at GANIL for Titanium beam production. Further tests using this ion source are under preparation for Ti and V beam production. Flux and angular distribution of atoms released by the oven are going to be measured off-line for optimizing crucibles geometries. Finally, the oven will be integrated into the Phoenix V3 ECRIS for Ti and V production. PB - JACoW Publishing CP - Geneva, Switzerland ER -
