With the goals to achieve low-emittance CW operation and to generate high average current electron beam, the second-generation DC-SRF gun, DC-SRF-II, has been developed. Efforts have been made recently to optimize the performance of the gun. In this work, we present the commissioning of the DC-SRF-II gun, with the focus on beam dynamics and related issues. ER -
