Proton Driver Rings Cost Estimates etc.
H. Schönauer

• First Partial Cost Estimate of Alternative RCS
  Scenario
• Upgraded Partial Cost Estimate of PDAC Reference
  Scenario
• Comparison
• Foil Heating Problem at 50 Hz
• Transfer Lines SPL - Accumulator Shortened
  version based on wiggler momentum collimator
  under evaluation

Next Steps...

• Transfer Lines SPL - Accumulator (cf. Sitemaps in
  .pdf)
• Shortened version based on wiggler momentum
  collimator is being refined - efficiency to be
  checked by tracking
• Injection Layout
• Collimation
• Writeup
