|Description:|| Recently, the AARTFAAC hardware required in the LOFAR superterp stations has been produced: 24 URI (UniBoard Ring Interface) boards(*), 12 UniBoards (2 per station) and 12 XGBs (10 Gigabit extension boards). All units are being evaluated thoroughly by Gijs Schoonderbeek and Sjouke Zwier.|
The goal of the AARTFAAC project is to correlate all (288) LBA dipoles on the superterp with each other, giving 288x288/2=41.472 correlation products. With a bit of software, this represents a highly sensitive all-sky detector for transient phaenomena, i.e. astronomical sources that change in brightness (or polarization) on a relatively short time-scale.
In addition, 6 URI boards have been made for Oxford University, for their single-station correlator.
(*) URI: boards that bend data instead of spoons.
