Abstract

The Atacama Large Millimeter Array is an array made of 64 antennas, observing the Universe in the sub-millimeter wavelength range. As technical leader of the consortium dedicated to the design and construction of the European antennas, EIE is in a unique position to evaluate possible improvements of the design. EIE has initiated an internal development, to evaluate to what extent it is possible to increase the dish diameter of the antenna, while keeping the surface and pointing accuracy achieved with ALMA. This paper presents the results of such activity.
