  1. High Level ApplicationsFacility Advisory Committee MeetingOct 30, 2007 • Applications Team • Current State of High Level Applications • Plan for 2008 Commissioning • Infrastructure and Project Management

  2. Applications Team • Greg White • Sergei Chevtsov • Paul Chu • Diane Fairley • Chris Larrieu • Debbie Rogind • Mike Zelazny

  3. Phased Development of LCLS Applications

  4. Applications provided by the Legacy system • The slc-aware IOC allows the legacy system to control and readback all new magnets, and provides beam synchronous data to High Level Applications in the Legacy system from: • BPMs, Faraday Cups, Toroids • Still to complete: LLRF phase and amplitude • Highest priority: A new Save/Restore app is needed to handle both existing and new devices

  5. Save/Restore Requirements - Groups • System and User Groups • System - organized by SLC regions • Injector, 21-BSY, LTU-Dump • User - on the fly • Groups of groups • Configure wildcarded lists of signals & associated readbacks, thresholds, status… • Compare against master RDB • Resolved via user command; upon Save (Create Snapshot) • Group relationships - track overlapping signals • Subsystem/device behaviors • Multi-step restore • Post-restore processing • Conditional save/restore • API • BPM Reference orbits, Multi-device knob,… • Export to File, Print

  6. Save/Restore Requirements - Snapshots • Repositories - Normal, Scratch, Temporary with different retentions • Tags - Current, Gold, last loaded, … • Retrieval via search mechanism – by group, repository, date, title, author, tag, comments • Comparison of multiple snapshots in the same group • Display snapshot by subsystem, area; report disconnected signals • Comparison of live values to stored; readback comparison to assess restore success • Programmable signal threshold for compare color coding • Edit data values prior to restore, then “save as” • Restore • Partial • Multi-step (Activate, Trim) • Conditional, Post-processing • Report restore status; Roll-back option • API • Export to File, Print • Error/cmlog logging, log-book

  7. Save/Restore Phase 1 – SCORE Modifications • XAL SCORE satisfies many requirements • Will service all magnets, LLRF, new timing, all new epics subsystems • Data Provider - add AIDA • Determine SLC/EPICS data source per signal • Implement polling of AIDA devices to get data • Modify AIDA SLC Magnet Data Provider • Processing - add Multi-step restore for magnet subsystem • RDB – add APEX support • Highly capable APEX app -upload spreadsheets to populate groups; duplicate/ integrity signal checking • GUI • Rearrange/add columns; modify comparisons • Add error/cmlog logging

  8. Save/Restore Phase 1 – LCLS SCORE

  9. Save/Restore Configurations

  10. Save/Restore Phase 1 – APEX

  11. Save/Restore – Phase 2 Conceptual Design

  12. Applications provided in MATLAB • Image Management • Bunch Length Measurement • Beam-based Feedback prototypes (separate talk) • Infrastructure support for MATLAB applications written by physicists

  13. MATLAB Bunch Length Measurement

  14. MATLAB Image Management

  15. Infrastructure Support for Physicists • MATLAB Programmer’s Guide • LabCA gives MATLAB scripts access to EPICS PVs • AIDA gives MATLAB access to SLC Data: • Model, • Archive/history, • Klystron, • Magnet, • Synchronous BPM.

  16. Infrastructure for Physicists

  17. Applications provided in Java/XAL/Eclipse • Modelling • New Configs • Orbit Apps, Correlation Plots • Data Utilities, like history, PV browsing, probe.

  18. Applications for 2008 Commissioning • Save and Restore - (Phase 1 Dec 2007; 2 summer 2008) • XAL Modelling (Dec 2007) • Model generation from device DB • Tracking • GUI • Orbit Display (Dec 2007) • Model Diagnostics (Dec 2007) • Matlab Feedbacks (Dec 2007) • Start-to-end Simulation (Phase 1 Dec 2007; 2 Apr 2008; …) • Cmlog Browser (Dec 2007) • Orbit Fitting (Jan 2008) • Buffered BPM display (Feb 2007) • Orbit Correction (June 2008) • Linac Energy Management (LEM) (summer 2008) • Correlation Plots (Jan 2009)

  19. SLAC Eclipse Accelerator Lab (SEAL) • XAL model generation • Database -> XAL optics file • XAL code separation • XAL online model application • Accelerator optics selector • Online model run control • Orbit data display • Model Diagnostics, AidaWeb • Cmlog Browser • History Browser, PV Table (CSS) • Textual display utility • Screen snapshot utility

  20. Bringing up probe editor Run online model Accelerator/sequence Chooser plug-in Data display selector XAL plotting package And synoptic display XAL in SEAL • All but XAL frame GUI classes are available in SEAL.
