- Millimetron is a Russian-led 12 m diameter submillimeter and far-infrared space observatory which is included in the Space Plan of the Russian Federation for launch around 2017. With its large collecting area and state-of-the-art receivers, it will enable unique science and allow at least one order of magnitude improvement with respect to the Herschel Space Observatory. Millimetron will be operated in two basic observing modes: as a single-dish observatory, and as an element of a ground-space very long baseline interferometry (VLBI) system. As single-dish, angular resolutions on the order of 3 to 12 arc sec will be achieved and spectral resolutions of up to a million employing heterodyne techniques. As VLBI antenna, the chosen elliptical orbit will provide extremely large VLBI baselines (beyond 300,000 km) resulting in micro-arc second angular resolution.

Konferensbidrag (refereegranskat)abstract
- We present here the stability results of the high frequency heterodyne instrument (HIFI), to be flown on the Herschel space observatory. The measurements were taken as part of the instrument level tests (ILT) in the spring of 2007. Herschel is ESA's fourth cornerstone mission in the Horizon 2000+ program, and aims at observations in the Far-InfraRed and sub-millimeter wavelength region. HIFI itself is one of three instruments onboard Herschel. The other two being PACS, the photodetector array camera and spectrometer, and SPIRE, the spectral and photometric imaging receiver.
