Abstract
The Expanded Very Large Array project has the top-level goal of enhancing the performance of the Very Large Array by an order of magnitude or more in all areas: sensitivity, frequency coverge, spectral resolution, and spatial resolution. The project is being implemented in two, overlapping phases: Phase I, which began in 2000 and will finish by 2012 addresses all new capabilities except spatial resolution, and Phase II, which will improve tenfold the spatial resolution, and which is planned to begin in 2006, and finish by 2013. Progress in Phase I is very good, with first light and first fringes having been achieved, and tests of the new hardware and software now underway. A proposal for funding Phase II has now been delivered to the National Science Foundation. A critical component of the project is the new correlator, being designed and built by the Canadian Herzberg Institute of Astrophysics at the DRAO in Penticton, BC Canada. This new advanced correlator will be delivered beginning in late 2008. First shared-risk science with the early portions of the correlator will be done in late 2007.
