A significant improvement in the performance of the BNL Mark III magnetron negative ion sources has been achieved by putting cylindrical grooves on the cathode to geometrically focus surface produced H− and D− ions into the emission slit in the a

Energy spectra of H− ions from a HDD source operating in mixtures of helium, hydrogen, and cesium reveal that negative ions are generated by a volume process and by a surface process. A marked difference was observed in the pressure dependence of t

Accelerating polarized protons to 22 GeV/c at the Brookhaven Alternating Gradient Synchro- tron required both extensive hardware modifications and a difficult commissioning process. We had to overcome 45 strong depolarizing resonances to maintain pol

Maintaining the proper low work function surface in steady‐state high‐current‐density negative ion sources is difficult, due to intense ion bombardment of the surface. Experiments were performed in which liquid cesium was forced through a porou

A parametric study was made of the pulsed hollow discharge duoplasmatron, operating as a negative hydrogen ion source in the pure hydrogen mode and in the mixed hydrogen–cesium mode. Effects of the arc current, gas pressure, and the magnetic field

A simple emittance measuring technique using emulsion detection has been applied to determine proton beam qualities up to 50 MeV and beam intensities up to 300 mA per 10 μsec. The evolution of beam emittances along the linear accelerator has been di

In order to get information about the excitation processes in a discharge tube, a spectrograph has been built, which scans the range between the visible and the far ultraviolet. Using a Paschen‐Runge mounting the spectrum has been detected with a c
