Outline Control System Scope and Organization Injector Control System Installation Technical Progress Project Status and Metrics Six month look ahead Summary

LCLS Control System is at WBS Level 3 John Galayda – Project Director Mark Reichanadter – Chief Engineer ----------------------------------------------------- Steve Milton – ANL Project Director Richard Bionta – LLNL Project Director e-Beam Dave Shultz Photon-Beam John Arthur Conventional Facilities Jess Albino Controls Manager Hamid Shoaee 1.2 Injector Manager Eric Bong 1.3 LINAC Manager Eric Bong 1.4 Undulator Manager Steve Milton 1.5 X-Ray ODT Manager Richard Bionta 1.6 End Station Stefan Moeller 1.2.2 Injector Controls 1.3.2 Linac Controls 1.4.2 Undulator Controls 1.5.2 XTOD Controls 1.6.2 XES Controls There are Controls Components in every WBS Level 2

LCLS Control System has larger scope than typical accelerator controls The scope extends from connection to beam line components, to data acquisition systems for end-station detectors Cable plant, racks, wiring, termination Global systems Magnet power supplies and control Vacuum Timing Networks, Servers, Control Room upgrades Safety systems Personnel Protection Machine Protection Beam Containment

LCLS Control System Scope… Beam Instrumentation & Diagnostics BPM Profile monitors and other beam imaging systems Toroid charge monitors Wire scanners Bunch Length Monitor High level applications software, physics modeling, feedback systems Experimental end station controls Laser controls, timing and synchronization X-Ray detector control software Spectrometer Control data acquisition & data management

LCLS Controls Group Staffing The control system development is performed by a matrixed group of about 50 engineers and technicians organized in two dozen engineering teams Each multi-disciplinary team manages the full product lifecycle from specification and design to engineering development, production, installation and commissioning Following a recent re-organization, the LCLS & SLAC controls effort have been integrated into one Controls Department The LCLS Control Group is now matrixed within the Control Department

LCLS Controls Group is now fully integrated & matrixed within the SLAC Controls Department

Controls ETC We have performed a bottom-up cost estimate of the remaining Controls effort from the injector through the experimental end station (XES) Identified a few systems with insufficient cost estimates, new scope, or cost changes due to changes in engineering approach Primary increases were in the areas of safety systems including MPS, PPS and BCS and power supply controls

Controls Cost and Schedule Variance Analysis SPI = .75 CPI = 1.02 Schedule variance = $589,984 Two factors are contributing to the schedule variance Beam Containment Subsystem -$275,427 This variance is real: We delayed procurement & fabrication until Oct-Nov. Installation will be complete in December to meet control system readiness milestone. Following work is completed and will claim BCWP in September E-Beam Diagnostics -$167,328 Timing Controls -$123,140 Vacuum Controls -$7,323 Software & Controls infrastructure -$16,766 TOTAL -$314557

Issues Several systems will be ready for installation in December, lather than we would like, but with no impact on the March Injector commissioning BPM electronics – The design has just been released for fabrication and assembly. Installation in December Toroid Charge Monitor electronics – The design has been completed, board layout next week, fabrication and assembly early November. Installation in December Timing system – software available in December, cable plant design almost ready for procurement XES Controls – large amount of controls development is required. We need to proceed with this work concurrent with Linac and Undolator controls effort.

Summary Great progress has been made in the past eight months towards readiness for injector installation All controls subsystems are expected to be available and tested for pre-beam checkout and March commissioning An ETC exercise has identified and fixed a number shortcomings in the baseline budget The integration of controls effort at SLAC is ensuring the availability of required expertise and resources to complete the control system development While commissioning the injector, we need to be mindful of the installation schedule for the rest of the machine including the experimental areas
