ACTPol
The second-generation, polarization-sensitive receiver ACTPol observed between 2013 and 2016. The four-year survey consists of 17,000 square degrees of the sky mapped at 98 and 150 GHz, with the deepest 600 square degrees at a noise < 10 uK-arcmin. This camera implemented multi-chroic polarization sensitive detectors operating at 100 mK. Highlights.

How does act telescope work?
A ground screen surrounding the telescope blocks contamination from microwave radiation emitted by the ground. The design, manufacture and construction of the telescope were done by Dynamic Structures in Vancouver, British Columbia . ACT can accommodate three instrument cameras simultaneously.
,
Is Act a cosmological error?
The results suggest that either there is a systematic error in one of the measurement methods or the current cosmological model is wrong. Located at an altitude of 5,190 meters (17,030 feet), ACT is one of the highest permanent, ground-based telescopes in the world.
,
MBAC
A first-generation receiver, the Millimeter Bolometric Array Camera (MBAC), mapped the CMB temperature anisotropies over an area of around 1000 square degrees from 2008 to 2010 with spectral bands centered at 148, 218 and 270 GHz and an angular resolution of 1.4 arcminutes at 148 GHz. Science highlights from these observations include:. 1) The first.

CBI
ASTE
Nanten
APEX and ALMA.
Atacama cosmology telescope (act)
The Atacama B-Mode Search (ABS) was an experiment to test the theory of cosmic inflation and distinguish between inflationary models of the very early universe by making precise measurements of the polarization of the Cosmic Microwave Background (CMB). ABS was located at a high-altitude site in the Atacama Desert of Chile as part of the Parque Astronómico de Atacama. ABS began observations in February 2012 and completed observations in October 2014.

Telescope in the Atacama Desert, northern Chile
The Atacama Cosmology Telescope (ACT) was a cosmological millimeter-wave telescope located on Cerro Toco in the Atacama Desert in the north of Chile. ACT made high-sensitivity, arcminute resolution, microwave-wavelength surveys of the sky in order to study the cosmic microwave background radiation (CMB), the relic radiation left by the Big Bang process. Located 40 km from San Pedro de Atacama, at an altitude of 5,190 metres (17,030 ft), it was one of the highest ground-based telescopes in the world.

Microwave telescope array in Chile
The Cosmology Large Angular Scale Surveyor (CLASS) is an array of microwave telescopes at a high-altitude site in the Atacama Desert of Chile as part of the Parque Astronómico de Atacama. The CLASS experiment aims to improve our understanding of cosmic dawn when the first stars turned on, test the theory of cosmic inflation, and distinguish between inflationary models of the very early universe by making precise measurements of the polarization of the Cosmic Microwave Background (CMB) over 65% of the sky at multiple frequencies in the microwave region of the electromagnetic spectrum.
