Schep}, title = {Investigation of 3d Effects on Fel Operation}, abstract = {An investigation is made of 3D effects on FEL operation by comparing the 3D simulation code TDA with a 1 1/2D model. In the latter model, the full spatial dependence of the radiation field is taken into account, whereas the electrons are treated as moving in a 1D, density-averaged ponderomotive potential. Three dimensional effects like a radial beam profile, emittance and betatron oscillations are investigated. For FELIX parameters, the 1 1/2D model is in good agreement with TDA.}, year = {1993}, journal = {Nuclear Instruments & Methods in Physics Research Section a-Accelerators Spectrometers Detectors and Associated Equipment}, volume = {331}, number = {1-3}, pages = {411-415}, month = {Jul 1}, isbn = {0168-9002}, doi = {10.1016/0168-9002(93)90081-r}, language = {eng}, }
