Abstract :
To prepare for a permanent wide-field, L-band phased array feed on the Arecibo radio telescope, a focal plane characterization experiment was conducted from July-August 2010. Experimental and numerical results indicate that a continuous field of view equivalent to 40 beams overlapping at half power is achievable.
