Status of dc H- ion source development for tandem accelerator of boron capture neutron therapy is described. Upgrade and study of the Penning surface-plasma source with hollow cathodes was continued. Results of source optimization, of ion optic computer simulation, and of emittance measurement are presented. The upgraded source delivers dc H- beam with energy 25 kV, current 8 mA, 1rms emittance JukcyX {approx} 0.2 {pi} mm{center_dot}mrad, JukcyY {approx} 0.3 {pi} mm{center_dot}mrad at discharge power {<=} 0.5 kW.
