摘要
The progress of a 2.45 GHz high-current microwave ion source with permanent magnet for T(d,n)(4)He reaction neutron generator is reported in this paper. At 600 W microwave power and 22 kV extraction voltage, 90 mA peak hydrogen ion beam is extracted from a single aperture of 6 mm diameter. The beam emittance is measured using a simplified pepper-pot method. The (x,x(')) emittance and the (y,y(')) emittance for 14 keV hydrogen ion beam are 55.3 pi and 58.2 pi mm mrad, respectively. The normalized emittances are 0.302 pi and 0.317 pi mm mrad, respectively.
