1. Control System OverviewApril 16, 2007Hamid Shoaeefor theLCLS Controls Group Outline • Injector control system installation & commissioning • Status update • Linac & beyond • Summary

2. Accomplishments in the past six months • Field installation of large amount of cable plant, networking, racks, electronics and software for injector control • Development of detailed plans for linac and BC2 installation • Coordination and re-planning of undulator control with ANL • Development of a conceptual design for X-ray End Stations DAQ and Controls • AIP projects for MCC networks upgrade, LCLS MPS and Linac BPM • Starting the design of next generation applications software

3. The main focus in the past six months has been the installation and commissioning of the injector Controls • Installation of the cable plant including trays, long haul DC and I&C cables, terminations, etc. • Phase 1 (Apr. ’06 thru Jun. ’06) • Phase II (Aug. ’06 thru Dec. ’06, including Christmas holidays) • Final terminations were occasionally delayed pending mechanical installations • Installation of the electronics racks, loading of crates, electronics chassis, modules, and intra-rack wiring • Installation of the Controls software on the front-end computers (IOC) and production servers

4. Phase II Installation Scope - Gun to TD11

6. MCC, Networks, Servers, & Workstations • Production Systems Delivered • Networks at S20 RF Hut & MCC: physical and wireless • LCLSDMZ, LCLS private, wireless • MCC infrastructure upgrade: power & racks • LINUX Servers for applications and EPICS data archiving • Control Room Linux Workstation • MCC and S20 Laser Room are actively in use for commissioning

7. Main Control Center is in full operation

8. All LCLS Safety Systems Are Operational • Laser Safety System (LSS) • Was needed early to allow laser commissioning • PPS • Passed many reviews by internal and external reviewers, citizens committees • The FIRST SLAC programmable PPS is online and operational • BCS • Prevents radiation from ‘escaping’ the shielding enclosure • Direct measurements of radiation or beam loss • Protection of safety-critical collimators and stoppers • The need for BCS was identified late, and the system had an aggressive schedule, but was completed and certified in time for ARR approval

9. Safety Systems – MPS • Interim MPS • Using existing linac infrastructure (1553 MPS) • Adding new signals and devices for LCLS • Interim MPS will be used for gating beam • Single Shot Mode • Burst Mode • Pockels cell and MPS mechanical shutter limit laser rate on cathode • LCLS MPS (presentation at break out) • Will be used to protect the undulator and photon sections • Held conceptual design review, now proceeding to detailed design

22. Monitoring front end computers (IOC)

23. Injection Laser Control System • The injector laser stabilization system includes two feedback loops • The first loop includes two mirrors, each with two actuators and one camera. It stabilizes laser traveling through a 10-meter tube • The second loop includes one mirror with two actuators and adjusts the laser position on the cathode. • The IOC reads the image from camera, calculates the laser’s position error and applies a correction to the actuators. • The loop operates @ 1 Hz, and the camera is synced to 120Hz.

35. Conclusions • The injector control system is online & operational • It has taken heroic effort by Controls group to meet the commissioning deadline • The plans are in place for linac & BC2 installation • We have developed a detailed plan for the undulator control in collaboration with ANL • A conceptual design is in place for X-ray End Station data acquisition and control • The major risk for the above items is schedule rather than technical complexity
