Abstract：
The Penning surface plasma source is adopted as the China Spallation Neutron Source (CSNS) H^- ion source. The designed energy and beam current of the source are 50 keV and 20 mA, respectively, with a normalized root mean square (norm. rms.) emittance of 0.2 πmm·mrad. The construction of a H^- ion source test stand has been completed, and the commissioning of the source is in progress. Stable H^- ion beams with energy of 50 keV and current up to 50 mA are attained. Emittance measurement for the H^- beam is being prepared.
