Materials

Assessing the radiation hardness of surface and bulk materials is of great importance to have global visibility of the ageing characteristics.

That’ s why TRAD has always been investing in efficient test facilities !

This year, we have launched Swipi, a low ernergy proton gun allowing reproduction of solar winds

Characteristics of Swipi - Solar Wind Proton Irradiation:

  • Protons Irradiation from 300 eV to 5 keV
  • Beam scanning : 65 mm in diameter with a current
    of 2 μA (1.25 1013 p.cm-2.s-1) to 1KeV
  • Temperature range : -185°C/+190°C
  • Liquid nitrogen cooling
Test sequence definition Radiative environment Testing

  • In accordance with ECSS-Q-ST-70-06C
  • Protons from a few keV to 3 MeV
  • Electrons from 100 keV to 10 MeV
  • Cobalt 60
