Abstract

The type of the H – ion source chosen for the China Spallation Neutron Source (CSNS) is the Penning surface plasma source. The designed output energy of the source is 50 keV and the pulsed beam current of H – beam is 20 mA with a rms. emittance of 0.2 πmm.mrad. The construction of the H – ion source test stand for CSNS is complete and commissioning of the source is in progress. Stable H – ion beams with currents up to 50 mA and energies of 50 keV are achieved. Emittance measurement of the beam is also being prepared.
