Query: FAST low frequency pulsar survey   The Five-hundred-meter Aperture Spherical radio Telescope (FAST) is under
construction and will be commissioned in September 2016. A low frequency 7-beam
receiver working around 400 MHz is proposed for FAST early science. It will be
optimized for a whole FAST sky drift-scan pulsar survey. Simulations show that
about 1500 new normal pulsars will be discovered, as while as about 200
millisecond pulsars.
