Total Ionizing Dose 4 New Space : TID 4 NS

The goal of the following slides is to provide the main "order of magnitude" for Total Ionizing Dose ( TID ) Levels, with reasonable accuracy,  on a circular orbit. The full Inclination vs Altitude "orbit space" is investigated. Each point is a full mission ( 200 orbits & 300 points/orbit ). Main space radiation figures are for  3 ; 4 ; 5 ; 6 & 7 mm Aluminum, which  is typically equivalent to  isotropic shielding for a NanoSat or MiniSat

Trapped electrons: AE8 Solar Maximum / Trapped Protons: AP8 Solar Minimum / Solar protons : ESP model @ 90% confidence level / 5 years

In order to be more representative of the reality, and to avoid over-estimation TID Levels are calculated at the center of an Al Solid CUBE (fig.1-b), and not inside a Solid Sphere (fig.1-a). As a reminder, TID Depth Curves for both shielding Solid Sphere & Solid Cube is given (fig.2)

  • INPUT   : Altitude in km, Inclination in °, mission Lifetime, Equivalent thickness of the satellite               
  • OUPUT : TID Level inside  a Solid Cube of the same thickness

The code TID4NS ( included into NT4NS ), elaborated to calculate these Isode Contours in a few seconds, will be available soon for the New Space community. With TID4NS code, it is possible to provide different thicknesses for the 6 faces of the equivalent Cube.
