Description
The Askaryan Radio Array (ARA) is an ultrahigh energy radio neutrino detector currently in the prototype and development phase. A testbed to examine the RF environment was deployed in the 2010-2011 polar season and is currently operating. A prototype ARA station is due to be deployed in 2011-2012. The testbed consisted of custom digitization and triggering for 8 antennas, digitized at 1 and 2 GSa/s, along with a commercial off-the-shelf single-board computer. The prototype ARA station, with 16 wider spaced antennas, presents additional challenges, with digitization at 3.2 GSa/s, and requiring an analog buffer of approximately 10 microseconds. The design and performance of the testbed, as well as the design of the prototype station, will be presented.
