Abstract

A microwave‐driven ion source being developed at TRIUMF is designed to produce stable, reliable, and gas‐efficient negative and positive ion beams for cyclotrons and other accelerators. The source has been tested for H⁻ and achieved 2.1 mA at 0.25 π mm mrad normalized emittance for 500 W of input power at a frequency of 2.45 GHz. The source was operated over one month without interruption for a H⁻ beam stability test and demonstrated 2.5% stability over the period. For positive beam extraction H⁺, He⁺, N⁺, and Ar⁺ species have been studied. A 2 mA N⁺ beam was obtained at 0.3 π mm mrad normalized emittance for 1 kW of input power. A beam density as high as 7 mA/cm² with 45% gas efficiency has been achieved for the Ar⁺ beam. In this paper the source parameters and characteristics are discussed.
