The first of six Band 5 receivers for ALMA

The first Band 5 receiver for the Atacama Large Millimeter/submillimeter Array (ALMA), delivered to ESO at the end of 2010. These are the world’s most sensitive receivers for radio waves with wavelengths around 1.5 millimetres — a wavelength range known as Band 5 at ALMA. They will allow scientists to trace water vapour in the nearby Universe, and will also provide an unprecedented view of the most distant galaxies. The development of the receivers has been led by the Group for Advanced Receiver Development at Onsala Space Observatory and Chalmers University of Technology in Sweden and the STFC–Rutherford Appleton Laboratory (RAL) Millimetre Wave Technology Group in the UK.
