ALMA’s Band 10 Receiver
Pictured here is one of the cold cartridge assemblies of the Band 10 receiver, which gives ALMA its highest-frequency capabilities. The Band 10 receiver can only be used under ideal conditions when there is minimal water vapor present in the atmosphere above the already arid Atacama Desert. Use of this receiver recently allowed astronomers to detect steams of heavy water (HDO) and complex molecules in a region of the Cat’s Paw Nebula.
