Description
Imagine of building a bolometric camera, sensitive to polarization, housing 2000 Transition Edge Sensors, sensitive to two frequency bands centered at 150 and 220 GHz, cooled down to 0.1K. How it would look like? What do you think would be the challenging aspects?
Now. Imagine this camera at the focus of a 6 meter telescope in the Atacama desert, in Northern Chile. What do you think would be the science targets of this camera?
I will walk with the audience through these, and many more, questions, presenting Advanced ACTPol, the new bolometric camera of the Atacama Cosmology Telescope.
