Achieved stable beam acceleration with 7 mA current.

Demonstrated effective RF control of multiple cavities.

Abstract

The High Intensity Neutrino Source (HINS) Six-Cavity Test has demonstrated the use of high power RF vector modulators to control multiple RF cavities driven by a single high power klystron to accelerate a non-relativistic beam. Installation of 6 cavities in the existing HINS beamline has been completed and beam measurements have started. We present data showing the energy stability of the 7 mA proton beam accelerated through the six cavities from 2.5 MeV to 3.4 MeV.
