Joseph W. The Atacama Cosmology Telescope ACT is a new, 6-meter aperture, millimeter-wave telescope that will be located at an altitude of meters in the Chilean Andes.
The camera will consist of three arrays for multi-frequency ground-based millimeter observations near , and GHz. The goal is to map the cosmic microwave background and discover Sunyaev-Zel'dovich clusters. Associated follow-up observations of the clusters will be taken at optical and X-ray wavelengths.

The South Pole Telescope. John Ruhl ; Peter A. Ade ; John E. Greer ; Nils w. Halverson ; William L. Holzapfel ;et. A new 10 meter diameter telescope is being constructed for deployment at the NSF South Pole research station. The telescope is designed for conducting large-area millimeter and sub-millimeter wave surveys of faint, low contrast emission, as required to map primary and secondary anisotropies in the cosmic microwave background. To achieve the required sensitivity and resolution, the telescope design employs an off-axis primary with a 10 meter diameter clear aperture.
The full aperture and the associated optics will have a combined surface accuracy of better than 20 microns rms to allow precision operation in the submillimeter atmospheric windows. The telescope will be surrounded with a large reflecting ground screen to reduce sensitivity to thermal emission from the ground and local interference.
The optics of the telescope will support a degree field of view at 2mm wavelength and will feed a new element micro-lithographed planar bolometric array with superconducting transition-edge sensors and frequency-multiplexed readouts. This survey should find many thousands of clusters with a mass selection criteria that is remarkably uniform with redshift.
Armed with redshifts obtained from optical and infrared follow-up observations, it is expected that the survey will enable significant constraints to be placed on the equation of state of the dark energy. CARMA: a new heterogeneous millimeter-wave interferometer. David P.
Woody ; Anthony J. Beasley ; Alberto D. Bolatto ; John E. Carlstrom ; Andrew Harris ; David W. Mundy ;et. The array will consist of 23 antennas of three different diameters, 3. The fist-light correlator is a flexible FPGA based system that will process up to 8 GHz of bandwidth on the sky for two subarrays consisting of 8 and 15 elements. The array configurations will offer antenna spacings from 5 m to 1.
This university based facility will emphasize technology development and student training along with leading edge astronomical research in areas ranging from Sunyaev-Zeldovich effect galaxy cluster surveys to studying protoplanetary disks. Mark J. Devlin ; Peter A. Ade ; Itziar Aretxaga ; James J. Dicker ; Matt Griffin ; Joshua Gundersen ;et. Advances in bolometric detector technology over the past decade have allowed submillimeter wavelength measurements to contribute important data to some of the most challenging questions in observational cosmology.
The availability of large format bolometer arrays will provide observations with unprecedented image fidelity. The large Atacama submillimeter telescope. Stacey ; Jonas Zmuidzinas ; David P. Woody ; Sunil Golwala ; Andrew Blain. Cornell and Caltech are undertaking a two year conceptual design study for a m class sub-mm telescope.
The nominal location for this facility will be the high Atacama Desert of Northern Chile. The baseline design is a segmented mirror telescope optimized for operation at wavelengths longer than microns to take advantage of a low precipitable water vapor at the site. We discuss science drivers and their implications for telescope design and technical requirements, and planned technical study areas. Bolometer Arrays: Current Developments. Michael Damian Audley ; Wayne S. Irwin ; Gene Hilton ; William D.
Duncan ; Carl Reintsema ;et. It will offer simultaneous imaging of a 50 sq-arcmin field of view at wavelengths of and microns. SCUBA-2 is expected to have a huge impact on the study of galaxy formation and evolution in the early Universe as well as star and planet formation in our own Galaxy.
SCUBA-2's absorber-coupled pixels use superconducting transition edge sensors operating at mK for performance limited by the sky background photon noise.
The monolithic silicon detector arrays are deep-etched by the Bosch process to isolate the pixels on silicon nitride membranes. We give an overview of the SCUBA-2 system and an update on its status, and describe some of the technological innovations that make this unique instrument possible. Bolocam: status and observations. Douglas J.
Haig ; Peter A. Ade ; James E. Aguirre ; James J. Bock ; Samantha F. Edgington ; Melissa L. Bolocam is a millimetre-wave 1. It has been commissioned at the Caltech Submillimeter Observatory in Hawaii and is now in routine operation. Here we give an overview of the instrument and the data reduction pipeline. We discuss models of the sensitivity of Bolocam in different observing modes and under different atmospheric conditions.
We briefly discuss observations of star-forming Galactic molecular clouds, a blank field survey for sub-millimeter galaxies, preliminary results of a blank-field CMB secondary anisotropy survey and discuss observations of galaxy clusters using the Sunyaev-Zel'dovich effect. Antenna-coupled bolometer arrays using transition-edge sensors. Michael Myers ; Peter A. Ade ; Gregory A. Engargiola ; William L.
We describe the development of an antenna-coupled bolometer array for use in a Cosmic Microwave Background polarization experiment.
