Introduction
• Source brightness has been increasing 1000x every decade
• Future challenges to understand dynamics and time evolution
• Requires improved coherence and energy bandwidth
– Short pulses and high brightness electron sources
– Seeding of soft and hard x-ray FELs
– Multiple pulses with timing control for pump probe
• Meeting these challenges will require advances in both
fundamental accelerator concepts as well as directed
development of accelerator science and technology
• Program will need a combination of quasi-parasitic use of
operating facilities and a diverse set of dedicated test beds
