## Present ESD EPICS

- PEP-II RF – 8 VXI-based stations
- Bunch Injection
- Damping Ring RF – Allen Bradley support
- Bucket-wise luminosity monitor
- NLC Test Accelerator – 2 VME IOCs
- 60/120 Hz pulsed operation
- PEP-II Tune tracker
- Other SLAC EPICS Projects
- Longitudinal Feedback – John Fox’s group
- SPEAR III upgrade (Ongoing)
- BaBar – Slow control – many IOCs.

## EPICS Tools and Applications

- StripTool is now a sine qua non of the control room
- Channel Archiver being mated to Oracle for speed and flexibility
- VDCT (newest Database Configuration Tool) now treated as a reliable tool.
- EDM (newest Display Manager) now available at SLAC for test
- Alarm Handler in use
- Strong core of EPICS developers, growing as we speak.

## Current EPICS Plans

- Upgrade PEP-II RF IOCs from niCpu030 to PPC VXI Controllers
- Move all production to 3.13.6 during the summer
- Provide SNL/SEQ support
- Continue to coordinate SLAC-wide EPICS
- Look seriously at RTEMS
- Switch to VDCT
- Keep abreast of 3.14 readiness
- Provide SLAC EPICS training

## LCLS Injector in EPICS

- SLC Timing

- Injector IOC

- Klystron 1

- Klystron N

- MPG
- Beam Codes
- BGRPS
- Etc.

- Timing slave to SLC
- Timing master for
- Klystron IOCs

- Evaluate APS / SNS
- timing systems
- All Klystrons either
- fully SLC or fully
- EPICS!

- ANL EPICS
- for Undulator
