Abstract:
The U.S. National Radio Astronomy Observatory (NRAO) and international collaborators have engaged the broad scientific and technical communities in the design of a next-generation Very Large Array (ngVLA), a large-scale radio astronomy telescope that is presently in the design phase. The ngVLA is envisaged as an interferometric array with ten times greater sensitivity and spatial resolution than the current VLA and ALMA telescopes, operating in the frequency range of 1.2 - 116 GHz. In this talk we provide an overview of the facility concept of operation and the present design baseline. We highlight the evolving concepts and remaining challenges for major system elements such as the reflector antenna, receiving electronics, data transmission, central signal processor and data post-processing systems. Speaker: Robert Selina is a Sr. Electronics Engineer with the National Radio Astronomy Observatory and Project Engineer for the next-generation Very Large Array. Prior to working on the ngVLA conceptual design, Rob was the lead for the VLA Systems Group, tackling system-level performance and maintenance issues and enhancements to the VLA telescope. He also served as Project Manager or System Engineer on a number of development projects such as the VLA Low-band Ionosphere and Transient Experiment (VLITE).
