The speed of the ALFA permits it to survey large areas of the sky quickly, while the telescope provides unequalled sensitivity. With the seven feeds it is also possible to detect structures which are too big to be seen with

utilizing the ALFA at
Arecibo Observatory. The telescope is not directed at preselected targets, but at one location for one night, allowing the sky to pass. This is called drift-scan. The goal is to find up to 25,000

The ALFA is a seven pixel detector and thus seven times faster than the previously used one pixel detectors. It is utilized in combination with the
Arecibo Observatory telescope, a 305-meter
