Acceleration performance of the INS 25.5-MHz split coaxial RFQ

Abstract

The INS 25.5-MHz split coaxial RFQ, which accelerates ions with a charge-to-mass ratio greater than 1/30 from 1 to 45.4 keV/u, is now taking acceleration tests with a beam of N{sub 2}{sup +}, N{sup +}, and Ne{sup +} ions. The electrodes are modulated vanes machined by means of the two-dimensionally cutting technique; consequently, the transverse radius of curvature at the vane tip is constant. Measured emittances and energy spectra of the output beam agree fairly well with the PARMTEQ simulation. The transmission efficiency data show that, in the beam bunching process, the longitudinal electric field is weaker than that derived from the two-term potential function but closer to that numerically computed by Crandall.
