LOFAR RF station at Chios (Greece)

Submitter: Ronald Halfwerk
Description: In the framework of the HELYCON project in Greece, the Engineering Department of the University of the Aegean did foresee the usage of low frequency antennas (40-80MHz, 40MHz bandwidth). Because of the very similarity with a LOFAR station, Prof. Gkialas and Dr. Papageorgiou selected this platform for one of their experiments on the island of Chios. The goal of HELYCON is to observe extensive air showers and to collect data corresponding to the flux, the direction and correlations between very energetic cosmic rays. In parallel this project aims to provide the educational platform to physics teachers, university and high school students to participate in a true scientific undertaking.

This 1LBH-station packed in a subrack/backplane contains LOFAR hardware like Receiver Units (RCU) , a Time Distribution board (TDB) , a Subrack Power Unit (SPU) , a Remote Station Processing board (RSP) and some additional clock generators to make this a stand-alone RF-station. Currently the station is equipped with one Low Band Antenna but by adding more RCU’s this station easily can be expanded.

Today, this station should be arrived at the University in Chios.
The picture shows the Euro-pallet of size 1.2x1,2x0,8m containing this 1LBH station ready for shipping. Despite the numerous tasks currently everyone has in the roll-out phase of LOFAR, Yde Koopman acting as project manager International LOFAR stations was able to slipstream this project with all other running activities to get things done. Not to forget mentioning Derk Kuipers who found creative ways to get heavy goods delivered on a too small island.

Chios is situated in the Aegean Sea, seven kilometers off the Turkish coast. Our Greek colleagues of course have intended the system for their specific project.
But when dreaming about large base lines!.....
