TOUPIE wind-tunnel pictures

 

 

Main design characteristics

 

  • Liquid helium wind-tunnel, He-I and He-II compatible
  • Pressurized to avoid cavitation in He-I
  • Operation from 4K down to 1.1 K
  • test-section : straight pipe, 90-cm-long and diameter up to 9-cm

 

This experiment has been cooled down for the first time in July 2010.

Partners

 

This work is a collaboration with G. Garde (design, fabrication, coordination of assembling, cryogenic tests...), P. Chanthib (in particular for the challenging pumping lines), P.-L. Delafin, J. Depont, E. Ghiringheli, assisted by Pr Guillet and Pr Kueny (ENSE3) for optimisation of parts of the wind-tunnel (cryogenic pump, ...).
