XFEL<br />
Oscillator<br />
• Existing FELs far from<br />
transform limit.<br />
• IR – UV FELs operate as<br />
oscillators – can this be<br />
extended to X-rays?<br />
• Use Bragg crystals as<br />
mirrors<br />
• Be Lens to focus<br />
• Expect 1MHz beam, 1ps<br />
pulses, 20MW peak,<br />
1.5x10 -7 B<strong>and</strong>width.<br />
• Cavity design / alignment<br />
is challenging<br />
