12. Dayle Kotturi Controls Overviewdayle@slac.stanford.edu April 29, 2004 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.
