A multicharge ion source (Supernanogan) for the OLIS facility at ISAC/TRIUMF

Area of Science:

• Nuclear Physics and Accelerator Technology
• Ion Source Development
• Radioactive Beam Facilities

Background:

• The Off-Line Ion Source (OLIS) facility utilizes microwave cusp, surface, and hybrid ion sources for various experiments.
• Existing sources provide +1 beams up to mass 30, suitable for initial commissioning and tuning.
• The Isotope Separator and ACcelerator (ISAC) facility requires higher mass-to-charge (A/q) ratios for full operational capability.

Purpose of the Study:

• To address the need for a multicharge ion source capable of delivering beams with A/q ratios up to 6.
• To enhance the experimental reach of the ISAC facility by enabling the acceleration of heavier ions.
• To commission and evaluate the performance of the newly installed Supernanogan multicharge ion source.

Main Methods:

• Installation of a Supernanogan multicharge ion source within the OLIS terminal.
• Commissioning of the Supernanogan source, including beam extraction and characterization.
• Performance evaluation focusing on emittance dependence of charge states and charge state efficiencies.

Main Results:

• The Supernanogan multicharge ion source was successfully installed and commissioned.
• The source demonstrated the capability to produce beams with A/q ratios up to 6, exceeding the limitations of previous sources.
• Initial performance data on emittance and charge state efficiencies were obtained and are presented.

Conclusions:

• The Supernanogan multicharge ion source significantly expands the capabilities of the ISAC facility.
• The new source enables experiments with a wider range of isotopes, particularly those with higher mass.
• The successful integration of the Supernanogan marks a key step in optimizing the ISAC facility's performance.
