  5. How? • Three pronged attack • Analyze requirements (& use institutional memory) • Establish core architecture & validate [TI8, SPS, LEIR, HWC] • Equipment & instrumentation access • Configuration, optics • Settings, trims • Measurements, logging, fixed displays… • Push novel control components • Post mortem • Real time • Injection control LHC Application development

  6. Development Process • OO analysis and design • Rational Unified Process • UML (Unified Modeling Language) • Iterative approach • Break project into chunks - modularization • Analysis, design, code and test • Plus exploration activity • Adaptive planning • Not fooling ourselves with illusory predictability • We do not have precise and accurate requirements • Agile Process • Short time boxed iterations bounded by milestones • Low in ceremony & lightweight LHC Application development

  7. Core architecture • Analyse the requirements of accelerator operations • Factor out the common functionality: • generic model • Implement once • Reuse for the control of several accelerators • Strategy: from simple to more general LHC Application development

  8. What is covered so far? • Optics • Layout, Twiss, strengths • Settings Management • Functions or values for all parameters (physics to hardware) • Settings Generation • Generation of the functions based on the optics • Trim • Coherent modification of functions, revert, history • Hardware & Instrumentation Exploitation • Equipment Control, • Measurements: log, archive & display • Operational Exploitation • Sequencing, Super Cycle changes LHC Application development

  9. How are we trying to do it? • Use a modern OO development method • Implement using appropriate technology • Using CO standards • Using standard components where possible • Aim for simplicity • Aim to for re-use in LHC domain LHC Application development

  10. What we have today ? • The data model has been defined and implemented • Software components and applications have been designed and implemented • Based on requirements from SPS, Transfer Lines (TT40/TI8) and with LHC in mind • Used successfully for the control of TT40 and TI8 • Applied successfully to model LEIR control • Work started to model LHC • Developments in place for HWC – reuse for beam based operation LHC Application development

  11. Architecture - Key Points • Principles • Modular • Distributed • Layered • Database Layer (Oracle) • Settings, trims, configuration, commands, optics, • Business Layer : all functionality required by applications • trim: change of parameter, conversion to hw parameter, record of changes, rollback, send to hardware etc. • measurement, acquisition, combination, filtering etc. LHC Application development

  13. Applications - Key Points • Using the new Application Frame • Released in the production area (via Common Build and Release) • Deployed via JavaWebStart • Accessible through the Console Manager • Able to run 2-tiers or 3-tiers • Accessing locally or remotely the business tier LHC Application development

  14. Systems to commission for injection –Controls and software • Requirements • Generic application software • Equipment control, measurement, data visualisation, cycle visualisation, trim, trajectory / orbit control, logging, alarms,… • Dedicated injection application software • Expert applications • A swathe of applications to get working….
