Equipment

We are continuously improving our state-of-the-art testing instrumentation that now includes:

  • Five home-made dilution cryostats with RF lines and optical access in our Néel space
  • One dilution cryostat installed at LPSC-Grenoble since 2021 (formerly NIKA and KISS)
  • One big dilution cryostat installed at the 30-meters telescope at Pico Veleta (NIKA2)
  • One dilution cryostat installed currently in Delft in the framework of the TIFUUN project
  • Sky Simulator
  • Two Martin-Puplett Interferometers for spectral characterisation
  • Polarisation-sensitive sources for high-resolution spectral characterisation between 30 GHz and 1.5 THz

In summary, we dispose now at Néel of three CONCERTO-generation cryo-free dilution cryostats and two liquid-helium dating from the NIKA generation. Five fully-equipped optical cryostats with base temperature from 50 to 150mK.

Pictues of our cryostats: NIKA0, NIKA1 (at LPSC), NIKA1.5, NIKA2 (at Pico Veleta), CONCERTO (C1), C2, C3, KAIROS-spin, TIFUUN (at TU Delft).

Pictures of the Sky Simulator, Martin-Puplett Interferometer, THz photo-mixer source, as an example of the equipment in our laboratory at Néel.

We work in symbiosis with the Cryogenics and Electronics groups at the Institut Néel.

NAI collaborates very closely, on a project-per-project base, with members from other laboratories like LPSC, IPAG, IRAM, LAM, and other international collaborators like Roma La Sapienza, INFN, CSIC, TU Delft, Cardiff, University of Minnesota etc.
