	Recent progress has been made at the newly commissioned Ion Source Test Facility (ISTF). Phase II, the final phase of the project, was completed in March 2016. First measurements were performed with D-Pace's TRIUMF licensed H⁻ ion source. The source was first characterized with H⁻ and an extraction study of the H⁻ ions was performed. A study of the production of heavy negative ions with volume cusp sources was started. Measurements with helium revealed no negative ions were extracted. Negative carbon ions were produced with acetylene. The beam composition has been analysed with a spectrometer.

	Volume-cusp ion sources require a fast and precise control algorithm to ensure the arc current, and thus the beam current is stable for high-power industrial DC operation. Using D-Pace's TRIUMF [1] licensed filament-powered H volume-cusp ion source, a proportional-integral-derivative (PID) control algorithm was implemented that provides a peak-to-peak beam current variation of ±0.45 % and a root mean square error of 0.025 mA for 10.16 mA of beam current over 60 minutes. The PID parameters were tuned for different set points and the performance of the algorithm is compared for the different settings. Measured arc current stability, and measured beam current as a function of time are presented and the algorithm utilized is described in detail.

Volume-cusp ion sources require a fast and precise control algorithm to ensure the arc current, and thus the beam current is stable for high-power industrial DC operation. Using D-Pace's TRIUMF [1] licensed filament-powered H volume-cusp ion source, a proportional-integral-derivative (PID) control algorithm was implemented that provides a peak-to-peak beam current variation of ±0.45 % and a root mean square error of 0.025 mA for 10.16 mA of beam current over 60 minutes. The PID parameters were tuned for different set points and the performance of the algorithm is compared for the different settings. Measured arc current stability, and measured beam current as a function of time are presented and the algorithm utilized is described in detail.
