Abstract
We describe a focal plane array (FPA) system, called Apertif, that is being developed for the
Westerbork Synthesis Radio Telescope (WSRT). The aim of Apertif is, at frequencies from 1.0 to
1.7 GHz, to increase its instantaneous field of view by a factor of 37 and its observing bandwidth to 300 MHz with high spectral resolution. This system will turn the WSRT into an effective survey telescope with scientific applications ranging from deep surveys of the northern sky of HI and OH emission and polarised continuum, to efficient searches for pulsars and transients. We present results obtained with a prototype FPA installed in one of the WSRT dishes. The results obtained with this prototype demonstrate that FPAs do have the required performance and that they can be used to turn radio telescopes into very effective survey instruments
