CRad is software for estimating the incidence of single- event effects (SEE) , displacement damage (TDD) and total dose effects (TID) on satellite orbits . It is a professional version of ForeCAST . The difference between the two is at the bottom of this page .
CRad's flow chart is also its interface:
The methods of SEE rate prediction are explained here. What CRad do includes:
The shielding effect of a space craft can be simplified as a thickness distribution of equivalent aluminum layers. To calculate the thickness distribution of a certain space craft, SSAT (developed by ESA) is employed. Due to different physics and geometry requirements, SSAT is not a part of CRad, but implemented in VisualParticle.
When predicting TDD and TID of devices in space orbits, Shieldose2 code, developed by NASA, is used for simulating the shielding of space craft shell. Three kinds of geometry model are supported by Shieldose2, including infinite-thickness slab, finite-thickness slab, and finite sphere.
ForeCAST is the on-line version of CRad.
