The EVLA (Phase 1)
The EVLA
Phase 1:
Frequency coverage: The EVLA will be able to operate at any
frequency between 1-50 GHz. Up to four
independently tunable pairs of frequencies in a given band.
Sensitivity: Continuum sensitivity to improve by factors
of a few (n<10 GHz) to more than a factor of 20 (n=10-50 GHz)
Spectral line capabilities: A new correlator will
provide many more frequency channels (at least 16384), process
up to 8 GHz
bandwidth in each pol’n channel, and provide much higher spectral resolution (as high as 1 Hz!).
Phase 2:
The primary goal of the second phase will be to
increase the
angular resolution of the VLA by
a factor of 10. This will be
done by incorporating the inner VLBA antennas and adding 8 new antennas: The New Mexico Array.
In addition, low frequency systems will be
installed at the prime focus and a new ultracompact array configuration will be
added (E configuration).
