  1. Controls Global Group Tasks John Carwardine Feb 8, 2006

  2. Focus on three areas… • Develop a reference design and costing for RDR • The high priority activity of GDE in 2006. • Continue to develop the baseline design • Pursue key R&D activities • LLRF development at various test stands (TTF, ILCTA, etc) • RF phase / timing distribution • High Availability

  3. Continue to develop the baseline design and BCD

  4. Instrumentation & Control outline in BCD • 11.1 Controls Standard Architecture • 11.2 Timing System • 11.3 Diagnostic Interlock Layer • 11.4 Global Network • 11.5 Machine Protection • 11.6 Low level RF • 11.7 Feedback • 11.8 Integration with Instrumentation • 11.9 Machine Detector Interface • 11.10 Instrumentation – Beam position monitors • 11.11 Instrumentation – Beam profile monitors (transverse) • 11.12 Instrumentation – Longitudinal • 11.13 Instrumentation – other (intensity, loss, ring)

  5. Control system architecture in BCD…

  6. Issues arisen from BCD Comments • Comments received from Toge, Lockyer, Himel • Communicate to technical system and accelerator area leaders the implications of ATCA and Control System High Availability. • Change baseline design from VME/VXI to ATCA. • Address failure modes for the rf phase reference distribution system (phase jumps). • We need more diagrams to communicate what the control system will look like (being done…)

  7. Main tasks still to do (BCD) • To be addressed by BCD section authors… • Update other BCD sections in response to comments. • Expand LLRF and feedback sections. • Respond to comments from Himel, Toge, Lockyer (written) • New summary has been written. • Submit case for ATCA instead of VME/VXI. • Submit updated BCD to CCB before Bangalore. • To be addressed by the Controls Topic Groups… • Understand requirements from accelerator areas. • Continue to develop control system design details. • Apportion the RF performance requirements across the subsystems.

  11. Pursue key R&D activities

  12. LLRF development • FNAL, DESY, KEK already actively pursuing this with regard to test stands (ILCTA, TTF, ATF-2, etc) • [Feb 9-10th workshop] • Should determine how we can best integrate the test stands into other controls related development activities.

  13. Timing / RF phase reference distribution Various issues discussed at Jan 19-20 meeting, including… • Evaluate and demonstrate various options • Trench test of fiber system (vs coil in oven) • Sector test – the copper part (local distribution). • Two-channel receiver comparator scheme • Low-cost way of building a vcxo with sufficient performance? • “To chop or not to chop” • Different schemes to meet the bunch compressor requirements. • Failure modes and effects analysis. • Pursue HOM phase detector scheme.

  14. Feedback development issues Various issues discussed at Jan 19-20 meeting, including… • How do the beam-based feedback systems deal with exceptions? • Startup, beam loss, MPS trip, etc • Detecting and handing bad sensors or actuators. • Integrated simulation of LLRF and beam-based feedback. • Interplay between the various feedbacks and feed-forwards? • How does beam-based feedback help the rf specs? • How many intra-train feedbacks do we have, and how many pulses do they collectively take to converge? • Should beam trajectory feedback be several individual loops or a single global system?

  15. High Availability control system demo • R&D Roadmap (starting point) • Claude’s proposal • ATCA + EPICS iocCore + shelf manager + ICE middleware • Claude to set up discussion with interested parties. • Develop an AMC module to plug in / integrate with Claude’s ATCA crate. • How do we utilize the test stands (ILCTA, ATF, TTF)? Feb 9/10 Fermilab mtg

  16. Develop a reference design and costing for RDR

  17. RDR Design Matrix

  18. “Charges for RDR Leaders” memo of 1/12/06 [see Ray Larsen’s table]

  19. Guidance for costing exercise • High level guidance • Expected margin of error for control system costing is +/-30%. • Focus first on overall ILC cost drivers first. • DCB looking for resolution of a few x 0.1% (~$50M). • Priority should be on a top-down rather than bottom-up costing. • Use what has already been done for NLC, TTR, USLCTOS, etc • The RDR is not a detailed design document. • Need to include ‘everything’ • We need to know what to cost and how many…

  20. Baseline is a High Availability control system… • Front-end hardware • Switch from VME to ATCA in baseline for RDR. • Need to know what needs hardware redundancy at front-end. • Servers etc • Need to budget for HA relational databases, software, central computing, data archivers, etc • Central computing + archiving + data backups, etc is part of controls domain. MIS computing is not. • Control system • We will provide infrastructure for implementing HA functionality. • We have to make the middleware reliable (especially). • Cost will be in implementing the recovery policies. • To what level do we go with HA software in the various layers?

  21. Main tasks to do (RDR and costing) • Develop WBS structure for Controls and LLRF. • Collect baseline info from accelerator areas. • Develop Control System and LLRF block diagrams. • Generate Excel spreadsheet of line items for costing exercise. • Meet RDR deliverables, as listed in the “Charge to RDR Leaders” memo. • Prepare for LLRF and Controls reviews in April/May. • Issue: an apparent lack of availability of people to work on RDR.

  22. Immediate tasks • Continue to develop the integrated control system diagram. • Develop an RF/LLRF block diagram of each accelerator area (linac is the most important to do first) • How many I/O + DAQ channels. • How many relay racks. • Cable plant. • Develop a controls block diagram for each accelerator area • How many I/O + DAQ channels. • How many relay racks. • Show interfaces to LLRF, Instrumentation, Timing, MPS, etc • Cable plant.

  23. Control System WBS outline • Global Control System • <List of global systems> • <Control system line items> • <Accelerator Areas> • <Technical Systems> • <Control System line items> • RF System • <LLRF line items> • <Control System line items> • We need information from the area and technical leaders to complete the Controls WBS for the accelerator areas.

  24. Control System WBS (Global level) • Global level (starting point) • Central computing • Networking infrastructure • Timing system / RF phase reference. • Central MPS • Personnel Protection System • Control Room(s) • Data archiving • Control System Software development • Installation / commissioning • Aim to develop a structure with nodes that can be costed and that can be cloned as needed.

  25. Requirements gathering exercise • Plan: • Appoint two points of contact (POC) for each of the six accelerator areas: one for LLRF; one for the Control System. • Appoint one POC for each of the five global groups. • Goals: • Get a broad-brush understanding of the scope of the control system requirements to be able to cost the control system. • Create building-blocks for the RDR costing exercise. • Help establish treaty points. • Initial deliverables from each Point of Contact • Block diagram showing functions and basic geographic layout. • Estimate of number of I/O channels and data rates.

  26. Proposal for accelerator area POCs

  27. Integrated control system block diagrams • We should develop a hierarchy of block diagrams for the integrated control system • Integrated control system functional diagram (Ned’s diagram) • Block diagram of each global subsystem • Timing, MPS, archiving, central control system, etc, etc • Block diagram of each accelerator area control system • E-, E+, DR, RTML, Linac, BDS • Block diagram of each accelerator area LLRF system • E-, E+, DR, RTML, Linac, BDS • Beam-based feedback. • Hardware/geographic and software centric views. • Each block becomes a node on the WBS.
