Geant4 simulations for IMPISH mission

Here are two Geant4 projects (similar, but with different goals) for the IMPISH mission.

See project readmes for more info.

import-capable

A Geant4 application employing the CADMesh package to import arbitrary shapes. Metadata is described with a small JSON structure per-shape, and each shape is imported into the geometry as a G4TesselatedSolid.

original-geant

A playground of sorts to build up some simulations comparing different rectangular prism geometries. The shapes are all coded in the Geant4 API which is not fun to work with.

Resources for simulating particle populations in LEO

From Patrick Dunn, we got some recommendations about how to simulate particle populations in LEO and perhaps elsewhere.

• For energetic (solar-system) particles: we can use the SPENVIS tool
• For other radiation stuff (dose?): we can use OLTARIS, which is kind of like SPENVIS.
• For galactic cosmic rays: we can use the Badhwar-O'Neill model
