Notes:
Several H−/D− dc sources employing multicusp confinement and magnetic filtering to enhance H−/D− production have been designed, built, and tested. Source performance in terms of beam output, emittance merit as functions of arc current, confinement magnetic strength, plasma volume, beam exit diameter, and extraction lens configuration have been studied in detail. At present, up to 9 mA H− and 3 mA D− beams with a normalized emittance of 0.44 mm mrad for H− beam have been extracted. A number of sources are tailored to fit the requirements of individual projects. In this article, a general description of source structure, power and biasing algorithms, and extraction geometries of these cusp sources will be given.
