Fast feedback is required to run at 120 Hz Values will be transmitted from RF and selected diagnostics to Power Supply and RF IOCs The communication needs to be reliable, verifiable, and have a well thought out degradation The entire time budget to read, transmit, communicate, control, and settle is 8.3 msec First estimates are that the control system can use 2 msecs to transmit and receive the data Can this be done over a common Ethernet with adequate bandwidth – or is a dedicated one needed?

Dayle Kotturi Controls April 29, 2004 Next 12 months Acquire team: 8 project engineers, 1 low level programmer, and 3 board designers – or contract out or steal designs Start PNet, Timing, LLRF, and BPM design efforts Start the SLC-Aware IOC development Put together detailed designs per subsystem and have them reviewed – revamp costs. Develop prototype for 120 Hz Fast Feedback Develop prototype for video diagnostics Develop prototype for position controllers

Dayle Kotturi Controls 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.
