Abstract

The world's largest low-frequency (10-250MHz) radio telescope, the pan-European Low-Frequency Array (LOFAR), is undergoing an upgrade of its hardware, firmware and software to improve its unique observing capabilities. The upgrade targets a variety of scientific use cases, ranging from galaxy evolution, transients and cosmic rays to space weather and lightning research. The LOFAR2.0 upgrade will increase the sensitivity of the telescope by doubling the number of digitized antennas operating in the 10-90 MHz frequency range, and allowing simultaneous observing with the antennas between 110 and 250 MHz. We present the validation of the LOFAR2.0 system following a stepwise approach, measuring its performance according to increasing complexity. Early integration test systems has ensured a smooth transition from validating a single receiver to the full-scale station. Subsequent array releases integrate the upgraded stations, combined with an upgraded clock distribution, network, central processor and telescope manager to validate the LOFAR2.0 telescope incrementally and ensure smooth transition to operations.
