| Abstract | The Next Generation Very Large Array (ngVLA) project to replace the VLA telescope in New Mexico continues to move forward. Concept designs for 15m, 18m, and 6m offset Gregorian antennas based on the Single-piece Rim-supported Composite (SRC) reflector concept have been developed at NRC, the 18m and 6m designs became part of the ngVLA System Reference Design (SRD). The Reference Design array is composed of a main array of 244 x 18m antennas and a short baseline array of 19 x 6m antennas. In the initial design iteration of the 6m antenna, as used in the SRD, was essentially a scaled down version 18m. This design exercise provided a costed concept appropriate for the SRD but did not meet one critical requirement; the ability to close pack the antennas. Following the release of the SRD the team at NRC took a clean piece of paper approach to the 6m antenna design driven by the close packing requirement. This paper will presents the design path from the ngVLA SRD to the latest design. |
