[97.03] CARMA: The Combined Array for Research in Millimeter-wave Astronomy

A.J. Beasley (CARMA/California Institute of Technology)

The Combined Array for Research in Millimeter-wave Astronomy is a heterogenous millimeter array under construction in the Inyo Mountains of eastern California. CARMA will merge the existing Caltech and Berkeley-Illinois-Maryland Association millimeter arrays into a single instrument focusing on astronomy research, technology development and student training. Eight additional 3.5-m antennas from the University of Chicago will also join the array after an initial standalone survey of the S-Z effect towards clusters of galaxies.

Construction has begun at a new high-altitude site which will enable improved year-round high frequency observing. At first light, the array will observe at 12, 3 and 1.3 mm using a mix of SIS and MMIC-based receivers. A new, highly-flexible correlator incorporating reprogrammable FPGA technology will process flexible subarrays of the antennas as specified by the science objectives.

The high sensitivity, sub-arcsecond angular resolution and excellent uv-coverage of CARMA will provide high-fidelity resolved images of solar-system objects, protostars, protoplanetary disks, and galaxies both nearby and at high redshift. In this talk I will review the technical developments and construction status of the array.
