Powerful cw proton linear accelerators (100 mA at 0.5–1.0 GeV) are being proposed for spallation neutron‐source applications. A 75‐keV, 110‐mA dc proton injector using a microwave ion source is being tested for these applications. It has achi

H− ion beams are extracted at 5–25 kV from a long, narrow slit on a Penning surface‐plasma source (the 8X source). The extraction geometry produces negligible transverse electric fields (focusing effects) along the slit length. Therefore, the i

After developing a pulsed 8X source for H− beams, we are now testing a cooled, dc version. The design dc power density on the cathode surface is 900 W/cm2, much higher than achieved in any previously reported Penning surface‐plasma source. The so

A pulsed 8X source was built and the H/sup -/ beam current, emittance, and power efficiency were measured. These results were promising, so a cooled, dc version designed for operation at are power levels up to 30 kW was built. Testing of the CW 8X so

Simple analysis of the nearly-Maxwellian angular distribution of the ribbon H{sup {minus}} ions beams extracted from a long, narrow slit on the 8X source yields the H{sup {minus}} temperature, kT{sub H{minus}}. The derived kT{sub H{minus}} are 0.1--0

Using the 4X source performance and the Penning SPS scaling laws, we predicted the performance of the 8X source. A pulsed 8X source was then built and tested. After verifying the pulsed 8X source operation, especially the H− beam current, emittance
