You could use potential energies but then have to rewrite the AlgorithmBSI accordingly to convert E- and B-field into the transmitted energy. Or you simply use an E-field threshold the way it is now. PMACC_CONST_VECTOR(float_X,,IONIZATION_EFIELD, , ... ); Every atom / ion species that you implement would need such a threshold list. You can specify the atomic properties for the species and set up particles::ionization::BSI as ionization model. The model is really not physically accurate but should be sufficient for high intensity lasers on sub-critical density targets.
