AI Article Synopsis
- The study simulates electron transmission through Mylar capillaries to understand guiding mechanisms.
- The findings reveal that electron guiding differs from ion guiding, relying on quantum reflection and near-forward scattering instead of charge up.
- The research indicates that similar guiding effects could be observed in metallic capillaries, showing strong agreement with recent experimental data.
Article Abstract
We simulate the electron transmission through insulating Mylar (polyethylene terephthalate, or PET) capillaries. We show that the mechanisms underlying the recently discovered electron guiding are fundamentally different from those for ion guiding. Quantum reflection and multiple near-forward scattering rather than the self-organized charge up are key to the transmission along the capillary axis irrespective of the angle of incidence. We find surprisingly good agreement with recent data. Our simulation suggests that electron guiding should also be observable for metallic capillaries.
