ANKA Absorber Design Storage ring: Lumped Absorber Distributed Absorber Front Ends. Mask Shutter
Basic Absorber 10000 W / K m2 40 W / mm Cu: Conductivity: 380 W / Km Young module 120 GPa Expansion 0.000017 1 / K
At the limit, what to do? Decline the Absorber 0.95 m > 1.7 m eff. Increase source distance: 1.3 m > 1.7 m Increase water flow Increase boundary surface Special: grooves and slots
