authors are researchers at the ENEA-Frascati Research Center in Italy. Giuseppe
Dattoli has been involved in high-energy accelerators, FELs, and applied
mathematics networks since 1979. Andrea
Doria's research interests include Cerenkov-based FELs and compact FEL sources
in the millimetre and far IR regions. Elio Sabia has been involved in
theoretical problems connected with particle dynamics in high-energy
electron accelerator-driven FELs. Marcello Artioli works on control systems and computer science.
