  Recently, we presented a new approach for a compact radio-frequency (RF)
accelerator structure and demonstrated the functionality of the individual
components: acceleration units and focusing elements. In this paper, we combine
these units to form a working accelerator structure including a matching
section between the ion source extraction grids and the RF-acceleration unit.
The matching section consist of six electrostatic quadrupoles (ESQs) fabricated
using 3D-printing techniques. The matching section enables us to capture twice
the amount of beam and match the beam envelope to conditions for an
acceleration lattice. We present data from an integrated accelerator consisting
of the source, matching section, and an ESQ doublet sandwiched between two
RF-acceleration units.
