Commissioning Plan
• 4-week Runs: 2 installation + 2 run– Started 2003 September– Initial sequence:
• First turn• Stored beam• Stacked beam• Vacuum conditioning• Radiation survey for licensing
– Goal:• 100 mA • > 6 hour lifetime• Good reliability and stability

Plan for 2004
• Q1:– SGM/PGM front-ends, POE and IDs– Optical chicanes for IR lines– Start of day-time operation
• Q2:– SM and PX front-ends, POEs and IDs– XAFS front-end and POE
• Q3:– XAFS wiggler– Tentative start of 24-hour operation
• Q4:– Increase current to 200 mA and lifetime to ~10 h

Future Projects
• Modifications for top-up operation
• Fast transverse feedback
• Linac modifications/upgrade
• Come to Sunday session to discuss other long range possibilities
