SWAS and Odin provided stringent upper limits on the gas phase water abundance of dark clouds (x(H2O) < 7x10^-9). We investigate the chemistry of water vapor in starless cores beyond the previous upper limits using the highly improved angular resolut

The Heterodyne Instrument for the Far-Infrared (HIFI) is a single sky-pixel, high-resolution (>300.000), spectrometer for ESA's Herschel Space Observatory. The instrument is designed to provide a wide and continuous frequency coverage with a velocity

Proceedings of the conference The calibration legacy of the ISO mission

We present a summary of all ground based SWS instrument tests and calibrations together with a description of test equipment and environment. The contents and results of the SWS ground calibration are discussed and their value for the in-flight calib

A fully superconductive integrated receiver is very promising for submm space astronomy where low weight, low power consumption, and limited volume are required. The new versions of the integrated quasioptical submm wave receiver have been designed,
