MADE IN NAOJ! ALMA Receiver development Part. 2

21 April, 2015 / Read time: 1 minute

This video presents the second part of the manufacturing process for the Japanese antennas’ sensitive receivers for the Atacama Large Millimeter/submillimeter Array (ALMA), developed at the Advanced Technology Center (ATC) of the National Astronomical Observatory of Japan (NAOJ). 

The manufacture of the delicate, exclusive parts that make up a receiver involves a creative production process of trial and error. These components are thoroughly checked and subjected to various tests to ensure that they are working correctly. Any faults found will result in a design change to increase the stability or durability of the part. 

Once the receiver is ready, it is carefully packed in special containers designed to absorb shock and vibrations, to ensure that it arrives in Chile with no damage to its delicate internal structure. 

Finally, the receivers are reviewed at the Operations Support Facility (OSF) in northern Chile. Once the simulation tests have been passed, the receivers are installed in the antenna cabins ready to receive signals from the Cosmos.
