Looking at the tortuous nature of the traversing path of electrons, these will interact or deposit the dose to the normal cells outside the affected area. So clinical application seems to be difficult.

I expect such a dose distribution because of the mixture of high and low energy electrons. I have problems to imagine a clinical target volume to be irradiated. It should have a broad volume near the entrance and diminuish in the depth, possibly like a cone shaped tumor volume.

I´m interested to see such a dose distribution from your simulations.
