Hello,

In past there were questions if Geant4 is capable to simulate plasma physics. The general answer: it is not excluded to use Geant4 infrastructure to create plasma application but we never work ourself in this field and did not imformed about any example (correct me if I am wrong).

In details:

User can describe his/her own material and add extra property, for example free electron density. User material may consist of only electrons. By default we do not have and have no example so far.

It is possible to use any material including user defined one to build geometry.

One need to review physics processes, because likely all cross sections are different for neutral and ionized atoms. Can some existing processes be used indeed (neglecting level of ionisation) - only plasma experts can tell.
