WG 2: Topics to discuss

Chair: G. Hoffstaetter, S. Smith

1.)

Is there an optimal bunch compression scheme for ERL light sources and how can bunch flattening schemes in longitudinal phase space be realized within such ERLs?

2.)

How can space charge and other emittance diluting effects be compensated in an ERL, especially in the injector and merger?

3.)

What needs to be remembered when designing a ring that should later be upgraded to an ERL?

4.)

What are diagnostic needs for light source ERLs?

5.)

What should front to end simulations for light source ERLs be sure to include?

6.)

What are good beam stabilization strategies and there limits for light source ERLs?

7.)

What are realistic beam abort strategies and beam loss tolerances for light source ERLs?

8.)

What are needs for vacuum and apertures in light source ERLs?

9.)

What are advantages and limits of multi turn ERLs?

10.)

What are the optimal parameters for superconducting cavities of an ERL light source?

11.)

At what loaded Q can an ERL be stabilized?

12.)

How should undulators for an ERL light source differ from those for ring sources?

13.)

What are critical issues that are common to all ERL projects?
