A channel access server in SLC provides data from existing SLC micros to EPICS applications
All IOCs have both a channel access server to allow access and a client to have access
Channel access provides read/write by all clients to all data with a server.
All EPICS high level applications are channel access clients that may or may not have a server.

Global Communication
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?

Machine Protection
Machine protection is used here to define faults requiring global mitigation
Response time is under 8 msec
There are two mitigation devices:
Single Beam Dumper - which prohibits the beam from entering the undulator
Drive Laser Off – which prohibits beam from entering the cavity
Action must also be taken to reduce the repetition rate of the beam
This new design is required to interrupt the beam before the next beam pulse.

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.

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.
