Operation of a high-current xenon source

Conference ·
OSTI ID:6231015
A multi-aperture Ehlers-type source has been constructed and operated to produce a 60 mA Xe/sup +1/ beam. The multi-aperture source utilizes a 13 hole aperture in a circular pattern producing a beam 25 mm in diameter. An accel--decel extraction system was used, producing a 22.5 keV beam whose normalized emittance at 29 mA was 0.027 ..pi.. cm--mrad. The neutralized beam was transported one meter through two magnetic quadrupole triplets to the entrance of a 20 cm accelerating gap consisting of five intermediate electrodes with a total voltage drop of 500 kV. The vacuum in the extraction region was held to 10/sup -5/ Torr by usng a puff valve and two 1500 1/sec turbo pumps. Multi-wire profile monitors just ahead of the column entrance measured the beam size, which was in good agreement with single-particle transport calculations.
