LORUN
LORUN stands for Low-Frequency Array (LOFAR), LOFAR at Radboud University Nijmegen. It is a radio telescope based on antennas designed for the THETA test station for the Low-Frequency Array (LOFAR), LOFAR radio telescope. This project is also closely related to the LOPES (telescope), LOPES Project, it uses the data acquisition program originally designed for LOPES.

Low-Frequency Array (LOFAR)
The Low-Frequency Array, or LOFAR, is a large radio telescope, with an antenna network located mainly in the Netherlands, and spreading across 7 other European countries as of 2019. Originally designed and built by ASTRON, the Netherlands Institute for Radio Astronomy, it was first opened by queen Beatrix of The Netherlands in 2010, and has since been operated on behalf of the International LOFAR Telescope (ILT) partnership by ASTRON. LOFAR consists of a vast array of omnidirectional radio antennas using a modern concept, in which the signals from the separate antennas are not connected directly electrically to act as a single large antenna, as they are in most array antennas. Instead, the LOFAR dipole antennas (of two types) are distributed in stations, within which the antenna signals can be partly combined in analogue electronics, then digitised, then combined again across the full station. This step-wise approach provides great flexibility in setting and rapidly changing the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Radboud University Nijmegen
Radboud University (abbreviated as RU, nl, Radboud Universiteit , formerly ''Katholieke Universiteit Nijmegen'') is a public research university located in Nijmegen, the Netherlands. The university bears the name of Saint Radboud, a 9th century Dutch bishop who was known for his intellect and support of the underprivileged. Established in 1923, Radboud University has consistently been included in the top 150 of universities in the world by four major university ranking tables. As of 2020, it ranks 105th in the Shanghai Academic Ranking of World Universities. Internationally, RU is known for its strong research output. In 2020, 391 PhD degrees were awarded, and 8.396 scientific articles were published. To bolster the international exchange of academic knowledge, Radboud University joined the Guild of European Research-Intensive Universities in 2016. Among its alumni Radboud University counts 12 Spinoza Prize laureates and 1 Nobel Prize laureate, Sir Konstantin Novoselov, the disco ...

LOPES (telescope)
The LOPES project ( LOFAR PrototypE Station) was a cosmic ray detector array, located in Karlsruhe, Germany, and is operated in coincidence with an existing, well calibrated air shower experiment called KASCADE. In 2013, after approximately 10 years of measurements, LOPES was finally switched off and dismantled. There are different ways to observe cosmic rays, or, more accurately, the air showers that cosmic rays produce when they enter our atmosphere. Traditionally, one directly measures the shower products that make it all the way to the surface. These may be detected by using for example particle counters. In the case of KASCADE, the muons in the shower produce a short flash of Cherenkov light when they traverse a slab of scintillator material. These flashes can be registered using photomultipliers. The LOPES project aims to demonstrate the feasibility of a different technique, in which not the shower products themselves are observed, but secondary radio radiation that is gene ...
