  11. Milestones (dependencies besides people) • Jan, 2005: Hardware available (FY05 funds in Oct) • Mar, 2005: Power supply controls ready (hardware) • Apr, 2005: Test stand set up in portable at sector 20 (hardware, beneficial occupancy of portable) • Jan, 2006: Network available (hardware, SCS install) • Feb, 2006: MPS, PPS, BCS controls ready (hardware) • Mar, 2006: LLRF gun controls (timing controls in SLC-aware IOC) • Apr, 2006: Vacuum controls (hardware) • Summer, 2006: Diagnostics as they are ready (hardware, timing) and the rest of LLRF controls as they are ready (LLRF gun controls) • Sep, 2006: Laser and laser heater controls (plan A)

  12. Conclusions • We need to acquire some key resources to get the critical designs well in hand before they are needed • Our key risk is in the design of an SLC-aware IOC and SLC to EPICS timing that will allow us to intermix the SLC and EPICS front-ends. It is also provides a valuable upgrade path for the SLC Linac. • We need to make Interface Control Documents for each control subsystem.
