| Abstract : | The Hydrogen Intensity and Real time Analysis eXperiment (HIRAX) is a radio interferometer, presently being developed, to survey large scale structures in the redshift range 0.7 < z < 2.5 over ~ 15000 sq. deg. of the southern sky through intensity mapping of the redshifted 21cm emission from neutral hydrogen. The array, in its final state, will consist of 1024 6m dishes arranged in a compact layout. In this talk, I will provide a status update on the array layout, dish, active feed and RFoF design, correlator and the various proposed backend. I will describe the various characterization activities taking place at various collaborating institutes and how they feed into the design process to minimize systematics as much as possible. I will conclude with plans for the upcoming dish verification array, the 256 element pathfinder and provide a road-map for expansion to the 1024 element array. |
