SUL Wiggler 27 periods of 74 mm, 1.5 T, K=6.4
• Installed in Dec 02• Baked and pumped down during the Christmas shut down• Operation resumed in Jan 03
• Smaller vacuum chamber, 16 mm vs 32 mm
30 % less injection efficiency
Partially compensated with slightly different optics

OverviewANKA is growing:
• 3 new beamlines
• 3 new front ends available
• 1 test front end for the SC mini-undulator
Forschungszentrum Karlsruhein der Helmholtz-Gemeinschaft
Summary
• ANKA runs reliable for users
• Standard user operation is stablished
• Three new beam lines will become operational during 2004
• SC mini-undulator will be tested with beam on 2004
