The Artistry of an ALMA Front End

The Artistry of an ALMA Front End

Behind the dish of each ALMA antenna sits one of these Front Ends, the chilled coolers that hold the suite of cutting-edge receivers. Each receiver was hand-crafted in one of three different laboratories around the world. They were brought together to be assembled into this cryogenic unit and shipped to Chile for installation inside each of ALMA's 66 antennas.
