Abstract
Abstract
The TRIUMF Stable Ion Source group has been developing negative and positive ion sources for decades, including a few arc-discharge H-/D- ion sources and a microwave-driven H-/D- ion source for medical cyclotrons [1] and other applications. The smallest ion source with a 125 cc plasma chamber can produce up to 5 mA continuously. The largest ion source with a 1200 cc plasma chamber is able to produce 60 mA with increased arc power and enhanced magnetic confinement. The filament-less microwave ion source is capable of producing up to 5 mA H- current for years without any manual intervention. A historical overview of H-/D- source development at TRIUMF is presented. A summary of employed optical and diagnostics components is also presented
