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
