TCD-15-38 - Low Frequency Array (LOFAR)

The Low Frequency Array (LOFAR) is a network of radio antennas spread across the Netherlands, France, Germany, Sweden, Poland and the UK operating at 20-240 MHz. Trinity College Dublin seeks to purchase and install an LOFAR station in Birr Castle in 2016, which will enable them to join the international LOFAR network. International LOFAR stations are composed of two arrays of antennas: 96 Low Band Antenna operating at 20-80 MHz and 96 High Band Antennas operating at 110-240 MHz. Each antenna contains a pre- amplifier that is connected to a signal processing electronics via coaxial cabling. The signal processing electronics are housed in a radio-frequency interference shielded shipping container. Once digitised, data are send via high speed fibre link (10 Gbs) to the LOFAR central processing facility in Holland. > > Further technical details on an international LOFAR station can be found at > http://www.lofar.org/wiki/lib/exe/fetch.php?media=public:2008-11- 24_doc_lofar_srs_019_iss1rev5_int-site.pdf
