Abstract
Astronomers want to have faster response times to stellar events and an increased sensitivity of radio astronomic interferometry methods that they use often. This requires a new data acquisition system to be developed to upgrade the several decades old existing systems in Europe. Due to the nature of radio interferometry and the several radio observatories involved, such a data acquisition system is inherently a distributed system. We will describe here some of the requirements of a new 10 Gbps network-connected data acquisition system. In addition, we present some results from evaluation tests that we have performed with consumer computers and 10 Gbps networking.
