J19: Antennas, detectors and receivers for new generation radio telescopes (2)

Saturday, August 23  09:40-10:40,  Room #12

The new generation of radio telescopes needs a new generation of receptors. This need for enabling technologies is driven by science requirements that call for increased bandwidth, field of view and sensitivity, but also by pragmatic requirements of low capital and operations costs. This session will highlight developments in radio astronomy receptors, from the capture of incident wave fronts through to digital outputs. Technical topics include electromagnetic design, antenna and feed structures, low-noise amplifiers, beamformers and digitizers.
