“…For both types of mixers a development to integrate mixers and pre-amp could simplify the instrument. Another development, the use of superconducting integrated receivers (SIR) with the (flux flow) local oscillator located on the same chip as the mixer, as is developed by Koshelets et al [12], could lead to more compact receivers. A SIR channel at 650 GHz has been integrated into the balloon-based atmospheric mission TELIS (Terahertz and submm limb sounder, see de Lange et al [13] and reference therein) for which a first flight is carried out in May 2008.…”

Many studies on the formation of stars and planets require high angular and high spectral resolution in the far-infrared regime. Even with the upcoming operation of the Herschel Space Observatory, ALMA, and JWST, angular resolutions of better than 1 arcsec combined with high spectral resolution in the crucial far-infrared domain of 1 THz to ~ 10 THz (300 µm to 30 µm) are still beyond observational reach. Only a far-infrared heterodyne interferometer can close this gap.Here we present the general requirements for a FIR heterodyne interferometer in space and address a number of critical key technologies needed for such an instrument.

“…The 480-650 GHz receiver channel is being developed in cooperation between IREE and SRON and is based on a single-chip Superconducting Integrated Receiver (SIR) that comprises on one substrate a low-noise SIS mixer with quasi-optical antenna and a superconducting Flux Flow Oscillator (FFO) acting as LO [15,16,17]. Tunability of the FFO shall allow for a wideband operation of this channel, with a goal to obtain 170 GHz instantaneous rf bandwidth or even more.…”

“…The most challenging part of the SIR channel is by far the phase-locked Superconducting Integrated Receiver (SIR) chip developed at IREE [15,16,17]. SIR comprises on one 4 x 4 x 0.5 mm 3 chip a low-noise SIS mixer with quasioptical antenna, a Flux Flow Oscillator (FFO) acting as Local Oscillator (LO) and a SIS Harmonic Mixer (HM) for FFO phase locking, see Figure 3.…”

TELIS (TErahertz and submm LImb Sounder) is a three-channel balloon-borne heterodyne spectrometer for atmospheric research. The observational techniques of TELIS can be compared to the presently flying MLS instrument on board NASA's EOS-Aura satellite, but TELIS is built with a new generation of cryogenic heterodyne detectors and novel compact systems suitable for integration into the confined space of a balloon borne cryostat. TELIS will fly on the MIPAS-B2 gondola. The two instruments together will yield the most complete set of stratospheric constituents, measured so far. TELIS is a cooperation between the European institutes DLR (PI-institute), RAL and SRON. First flight foreseen in the spring of 2008 from Teresina, Brasil.The three TELIS receivers provide simultaneous vertical profile measurement of a range of molecules. The 500 GHz channel is developed by RAL and will produce vertical profiles of BrO, ClO, O 3 and N 2 O. The 1.8 THz channel is developed by DLR and will mainly target the OH radical, and will also measure HO 2 , HCl, NO, NO 2 , O3, H 2 O, O 2 and HOCl. Finally the 480 -650 GHz channel is developed by SRON and IREE and will measure profiles of ClO, BrO, O 3 , HCl, HOCl, H 2 O and its 3 isotopomers, H 2 O 2 , NO, N 2 O, HNO 3 , CH 3 Cl and HCN.In this paper, the science and technology of TELIS will be discussed with emphasis on the channel developed by SRON. It contains a Superconducting Integrated Receiver (SIR), which combines on a 4x4 mm 2 chip the low-noise SIS mixer and its quasioptical antenna, a superconducting phase-locked Flux Flow Oscillator (FFO) acting as Local Oscillator (LO) and a SIS harmonic mixer (HM) for FFO phase locking. The latest results from the pre-flight test and integration campaigns will be presented.
