Telescopes

ASTRON is responsible for the operations of the Westerbork Synthesis Radio Telescope (WSRT) and the Low Frequency Array (LOFAR).

Astronomy

The astronomical research at ASTRON is closely aligned with the strengths of our facilities LOFAR and WSRT-APERTIF.

Beschermingszones


Met onze radiotelescopen nemen wij de meest zwakke signalen uit het heelal waar. Daardoor zijn zij kwetsbaar voor elektromagnetische storing. Met het tijdig treffen van de juiste maatregelen kan storing worden voorkomen.

Vidi grant awarded to astronomer Harish Vedantham

Astronomer Harish Vedantham of the Netherlands Institute for Radio Astronomy (ASTRON) and the University of Groningen has been awarded a ‘VIDI' grant of 800,000 Euros from the Netherlands Organization for Scientific Research (NWO).

What does the start of construction of SKA mean for the project and the Netherlands?

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.

Green light given for construction of world’s largest radio telescope arrays

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.

Apertif survey wraps up at end of 2021

The Apertif/ARTS surveys will wrap-up at the end of 2021. The WSRT observatory will of course continue to be operated, amongst other activities, as part of the European VLBI network.

CNC-milling a corrugated horn antenna

Today, a mechanical build worth sharing.

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!
