STORIES
At a historic meeting of its Council on 25 June 2021, the SKA Observatory (SKAO) saw its Member States give the green light for construction of the SKA telescopes in Australia and South Africa to commence. We spoke to Michiel van Haarlem, head of the Dutch SKA Office at ASTRON, about what this important milestone means.
At a historic meeting of its Council last week, the recently formed SKA Observatory (SKAO) saw its Member States approve the start of construction of the SKA telescopes in Australia and South Africa.

CNC-milling a corrugated horn antenna

Last month we were challenged by TU/e student Sjoerd Aker with a classic antenna design, a corrugated horn antenna or feed.
Our manufacturing approach however, was less obvious.
Starting off with a 75kg chump of aluminum, our CNC station reduced this to approximately 5% of its initial weight.
After some additional lathing, milling and hand laboring the additional parts such as semi-rigid cables, connectors, an orthomode transducer, 2-component resin and mounting, we received the satisfying message from the TU Eindhoven anechoic chamber that measurements succeeded!
