چکیده

The Atacama Cosmology Telescope is a 6 m telescope designed to map the cosmic microwave background simultaneously at 145, 215, and 280 GHz with arcminute resolution. Each frequency will have a 32 by 32 element focal plane array of transition edge sensor bolometers. The telescope and the cold reimaging optics are optimized for millimeter-wave observations with these sensitive detectors. The design of each is described.

Measuring two-millimeter radiation with a prototype multiplexed TES receiver for ACT

The Millimeter Bolometer Array Camera (MBAC) is sheduled for installation on the 6-meter Atacama Cosmology Telescope (ACT) in 2007. MBAC will eventually contain three diffraction-limited, 1024-pixel, focal plane arrays of Transition Edge Sensor (TES) bolometers developed at NASA Goddard Space Flight Center. We present instrument designs and results from optical and electrical measurements made ...

The 350 Micrometer Wavelength Superconducting Bolometer Camera for APEX

Since spring 2008, the Small Array Bolometer Camera (SABOCA) operates at APEX (Atacama Pathfinder Experiment), a 12 meter radio telescope on the high plateau Llano de Chajnantor in Chile's Atacama Desert. This instrument utilizes an array of 37 transition edge sensors to detect sub-millimeter radiation in a narrow band around 350μm wavelength, which fits the last useful atmospheric radio window...

The Atacama Large Millimeter Array (ALMA)

The Atacama Large Millimeter Array, or ALMA, is an international telescope project which will be built over the coming decade in Northern Chile. With over 7000 m of collecting area comprised of 64 12m antennas arrayed over baselines up to 14 km in extent, ALMA will provide images of unprecedented clarity and detail. One revolutionary feature of ALMA will be its ability to combine interferometri...
