TErahertz Limb Sounder (TELIS)

• TELIS Objectives
• Measure many species for atmospheric science
  (ClO, BrO, O3, HCl, HOCl, etc) -
  Chemistry, Transport, Climate
• Serve as a test platform for new sensors
• Serve as validation tool for future satellite
  missions

Superconducting Integrated Spectrometer for TELIS

• Concept of the Phase-locked SIR is developed and
  tested.
• Nb-AlN-NbN FFOs and SIRs have been successfully
  implemented (current density up to 20 kA/cm2
  tunnel barrier about 1 nm) .
• Improved design of the FFO for TELIS has been
  developed and optimized free-running linewidth
  from 0.5 to 10 MHz recorded in the frequency
  range 350 740 GHz that allows to phase lock
  from 35 up to 97 of the FFO power.
• 3-rd generation of the SIR with PL FFO for TELIS
  has been developed showing a possibility to
  realize TELIS requirementsFrequency range 500
  650 ??? Noise Temperature lt 150 ? IF bandwidth
  4 - 8 ??? Spectral resolution better 1 ???
  Beam Pattern - FWHM 3 deg, with sidelobes lt -
  17 dB.
• Procedure for remote optimization of the PL SIR
  operation has been developed and experimentally
  proven.
• The maiden flight took place in June 2008,
  (Terezina, Brazil).
• Approaches to increase SR of the PL FFO proposed
  and tested.
• Future space and ground-base missions are under
  consideration.
