  41. Know-how on LINACs - Generation of e-beams with photo-injectors - Beam phase-space manipulation - RF-power, Acceleration and Transport - Synchronization, Diagnostics & Control Will allow INFN to contribute with wider and stronger expertise to the future ILC project. Finally, - 5 thesis/year - 6 PhD - 6 Contracts (Ass. Ric., Art. 23) About 10 young Physicists and Engineers, with enthusiasm and motivations, are being educated in the field.
