• Charge to the working groups:
• Identify physics programme
• Identify scientific objectives and challenges of advanced accelerators
• Identify an Advanced Accelerator Project (medium/long term)
• Identify required high priority R&D, with possibly the construction of a test facility
• Identify partners and cost of R&D
• Detailed charge:
• Identify parameters/elements necessary for the scheme
• Determine to what extend they have been proved and demonstrated
• Evaluate likelihood and timescales for testing/proving solutions
• Identify key experiments to be performed
• Identify existing or new facilities to perform key experiments
• Identify realistic time scales
• Identify panorama, what is in the making?
