Holography has confirmed the excellent presetting of the reflector panels by laser adjustments to 40 µm rms. This result allows to integrate the antenna into the interferometer with full sensitivity right from the start. Eight antennas in the interferometer of course mean increased sensitivity but it is in particular the dynamic range of the imaging which makes a huge step forward.
The 9th antenna is already assembled up to the yoke and reflector construction will start in summer this year.
Meanwhile,more than half on the antennas are already equipped with the new NOEMA wide band receivers which show excellent performance and an extended and unique frequency coverage down to 72 GHz. Full receiver upgrade will be achieved in October this year.
