VEGAS: Versatile GBT Astronomical Spectrometer


Latest Status Update

NRAO in collaboration with the Center for Astronomy Signal Processing and Electronics Research (CASPER) at the University of California, Berkeley (CICADA collaboration) is building an advanced multi-beam spectrometer for the GBT. The National Science Foundation Advanced Technologies and Instrumentation (NSF-ATI) program is funding the new spectrometer project1. The new backend will replace capabilities of the existing spectrometers and will support data processing from focal plane array systems. Thus the capabilities of the spectrometer will be synergetic with the multi-pixel camera development program for the GBT. In the present design, the spectrometer will be capable of processing up to 1.25 GHz bandwidth from 8 dual polarized beams or a bandwidth up to 10 GHz from a dual polarized beam.
