Abstract
The Northern Extended Millimeter Array (NOEMA) is a facility which will focus on large surveys but at the same time generate together with ALMA all sky coverage in the millimeter range with similar sensitivities. NOEMA consists of twelve 15-meter antennas equipped with ultra-low noise SIS receivers covering the frequency range from 70 to 375 GHz. With a surface accuracy of 35 micrometer, the NOEMA antennas offer excellent efficiency for the wavebands in operation. The NOEMA receivers deliver dual linear polarization signals in separated side bands of 8GHz bandwidth each. The resulting total IF bandwidth of 32 GHz is processed in an advanced FX-correlator using high speed samplers and FPGA technology. The correlator offers simultaneously high efficiency for continuum and high resolution spectroscopy without any need for trade-offs. The final baseline length will be 1.7 km enabling resolutions down to 0.1". The key technologies used for NOEMA including the antenna technology are summarized and an overview on the actual status of the project and first science results will be given. Further upgrades such as a dual band extension for the coming years are already in preparation. The related technological developments including the path for efficient short spacing measurements with the IRAM 30m telescope are shortly outlined.
