SPIS down-to-Earth?

Dear All,

I would like to know whether it is possible to use SPIS to simulate a ground test chamber environment. The chamber would have a steel wall, maintained at a potential of 0 V, ideally with some modelling of secondary electron emission.

So far the best idea I have come up with is to define the external boundary of the computational volume at the inner surface of the chamber, but this rules out any surface interactions. I also do not know how to maintain a fixed potential at the external boundary.

I have also tried deliberately making a hole in the chamber wall so that it can float as a complete entity in empty space, but of course the plasma leaks through the hole, and the potentials change!

I would be very grateful for any suggestions or advice.

Thanks and Best Regards,

David.
