The 3 (84-116 GHz), 2 (130-180 GHz) and 1 mm (211-275 GHz) bands will employ ALMA-type, sideband-separating (SBS), superconducting (SIS) mixers, which represent the world's best in sensitivity and stability.

The dual-polarization 4-band receiver will cover the astronomically important atmospheric windows at 1, 2, 3, and 4 mm wavelength regions well suited to the Kitt Peak site. As such, they are among the few remaining opportunities for direct student involvement in radio telescope instrumentation and operations. This telescope, along with the ARI 10 m telescope on Mt Graham, are perhaps the only remaining general purpose radio telescopes operated by a US university. The program will incorporate significant student training at all levels, from high school through graduate school. community to access ARO's unique northern hemisphere observing capability and to enable pathfinder science for ALMA. As part of this program ARO will allocate 28 days of observing time per year to the general U.S. astronomers and scientists from universities and national labs, the Event Horizon Telescope consortium, and the European Southern Observatory (ESO).
The new receiver and 12 m antenna will have a broad user base with U.S. The receiver will cover the 1-4 mm wavelength range in four separate bands, and will enable a broad range of astronomical research including spectroscopy of molecular clouds and planetary nebulae, astrobiological studies of disks and pre-biotic molecules, and the study of black holes.

The subject proposal funds a modern, multi-wavelength receiver system which will realize the full scientific potential of the new ARO 12 m antenna. After acquisition, the UA moved their APA to Kitt Peak, replacing the 40-year-old 12-m telescope, and rechristening the telescope as the new Arizona Radio Observatory (ARO) 12 m. After completion of the ALMA testing and evaluation phase, the Arizona Radio Observatory (ARO) at the University of Arizona (UA) acquired one of the two APA telescopes. As part of the development phase of the Atacama Large Millimeter Array (ALMA), two 12 meter ALMA prototype antennas (APA) were constructed for evaluation and testing, and installed at the National Radio Astronomy Observatory (NRAO) Very Large Array (VLA) site in Socorro, New Mexico.
