The High Intensity Neutrino Source (HINS) R&D program at Fermilab will build a new 65 MeV test linac to demonstrate new technologies for application in a high intensity hadron linac front-end. The HINS warm section is composed of an ion source, a radio frequency quadrupole, a medium energy beam transport and 16 room temperature Crossbar H-type (RT-CH) cavities that accelerate the beam to 10 MeV (β=0.1422). The RT-CH cavities are separated by superconducting solenoids enclosed in individual cryostats. Beyond 10 MeV, the design uses superconducting spoke resonators. In this paper, we illustrate the completion of four RT-CH cavities and explain latest modifications in the mechanical and radio frequency (RF) designs. Cavities RF measurements and tuning performed at Fermilab are also discussed. Descriptions of the HINS R&D Facility including high power RF, vacuum, cooling and low level RF systems will be given. Finally, the history of RF conditioning and the results of high power tests of RT-CH cavities will be discussed.

The High Intensity Neutrino Source (HINS) linac R&D program at Fermilab aims to construct and operate a first-of-a-kind, 60 MeV, superconducting H- linac. The machine will demonstrate acceleration of high intensity beam using superconducting spoke cavities from 10 MeV, solenoidal focusing optics throughout for axially-symmetric beam to control halo growth, and operation of many cavities from a single high power rf source for acceleration of non-relativistic particles.
