During the last three decades, TRIUMF has developed H -cusp ion sources for the 500 MeV, TR30, TR13 cyclotrons, as well as many other machines. These ion sources can be categorized as high current versions, producing up to 20 mA of DC H -beam within a normalized emittance (4RMS) of 0.6 ʌ-mm-mrad and low current versions, producing up to 1 mA of CW current within a normalized emittance (4RMS) of 0.16 ʌ-mm-mrad. A new state-of-the-art test stand is being built to further enhance H -knowledge while improving the brightness and filament life. The preliminary results of the test stand performances, as well as relevant emittance measurements, are discussed.
