Development of a 110-m-mA, 75-keV proton injector for high-current, CW linacs

PDF Version Also Available for Download.

Description

A dc proton injector is being developed for a 6.7 MeV CW RFQ at Los Alamos. The RFQ input beam requirements are 75 keV energy, 110 mA dc proton current, and 0.20 {pi}mm-mrad rms normalized emittance. The injector has now produced a 75-keV, 117-mA dc proton beam (130 mA total current) with the required emittance. The emittance has been measured after a 2.1 m long two-solenoid beam transport system. The measured emittance can be explained in terms of the ion source emittance and beam transport through the focusing elements. Measured proton fractions are 90-92% of the beam current.

Engineering of the accelerating column high-voltage design is being improved to increase the injector reliability. Injector design details and status are presented.
