Abstract:
The TELIS (Terahertz and sub-millimeter limb sounder) instrument is a three-channel heterodyne receiver developed for atmospheric research. TELIS is mounted together with the MIPAS-B2 instrument on a balloon platform of the Institute for Meteorology and Climate Research of the Karlsruhe Institute of Technology. TELIS can observe both in the sub-millimeter range (480-650 GHz) and at 1.8 THz, while MIPAS-B2 observes trace-gases in the thermal infrared window. Results are used to refine and constrain numerical chemical transport models. The SRON contribution to TELIS is the 480-650 GHz Superconducting Integrated Receiver (SIR) channel. This is a unique superconducting on-chip heterodyne receiver, consisting of a double dipole antenna, a SIS mixer, a flux-flow Local Oscillator, and a superconducting harmonic mixer used for phase locking of the LO-signal. The lowest noise temperature of the receiver is 120 K DSB, measured over the full IF bandwidth (2 GHz).
