Status of the SPIRAL2 injector commissioning

Area of Science:

• Nuclear Physics
• Particle Accelerators
• Ion Source Technology

Background:

• The SPIRAL2 ( f rench : Systeme de Production d'Ions RAdioactifs en Ligne 2 ) facility at GANIL is a next-generation accelerator designed for producing radioactive ion beams.
• Commissioning of the SPIRAL2 injector is crucial for its operational readiness and scientific output.

Purpose of the Study:

• To report on the commissioning status of the SPIRAL2 injector.
• To introduce the PHOENIX V3 heavy ion source upgrade and its expected performance improvements.

Main Methods:

• Installation and commissioning of two low-energy beam transport lines for light and heavy ions.
• Utilizing a 2.45 GHz electron cyclotron resonance ion source for light ions.
• Employing the PHOENIX V2 18 GHz heavy ion source and presenting the design of its successor, PHOENIX V3.

Main Results:

• Successful production of the first light ion beam in December 2014.
• Analysis of the first PHOENIX V2 heavy ion beam on July 10, 2015.
• The PHOENIX V3 features a doubled plasma chamber volume, with expected intensity increases of 1.5-2x for high charge state beams up to mass ~50.

Conclusions:

• The SPIRAL2 injector commissioning is progressing, with initial light and heavy ion beams successfully produced.
• The PHOENIX V3 upgrade represents a significant advancement in heavy ion source technology, poised to enhance SPIRAL2's capabilities for future experiments.
