Description
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 offline
for optimizing crucibles geometries. Finally, the
oven will be integrated into the Phoenix V3 ECRIS for
Ti and V production.
