  1. Damping Rings KOM and EDR Planning M. Palmer Cornell University Magnets Technical Group Meeting October 18, 2007 Magnets Technical Group Meeting

  2. Outline • DR Planning Status • Structure of DR KOM • DR Magnets-related Planning for the EDR Phase • Proposed Work Packages • Proposed WP Coordination • Plans for ‘Magnets & PS’ Presentation and Discussion at KOM Magnets Technical Group Meeting

  3. DR Planning • EDR Kick-off Meeting • Nov. 5-7 at Daresbury Lab • Smaller footprint than some other KOMs • Tentative Schedule: Aim is for a 60/40 split talk/discussion Magnets Technical Group Meeting

  4. DR KOM II • Magnet System-Related Presentation • Magnet & PS Talk • 1.5 Hours (Palmer) • Covers: • Conventional Magnets • Wiggler • Power System • Injection & Extraction System Talk • 1 Hour (Mattison) • Covers: • Fast kicker structures • Fast Pulsers • Other pulsed elements (inj/ext/abort lines) Magnets Technical Group Meeting

  5. EDR Organization – So Far • Proposed DR Work Packages: WP 1: Lattice Design and Acceptance WP 2: Orbit, Optics and Coupling Correction WP 3: Damping Wiggler Design WP 4: Instrumentation and Diagnostics WP 5: Impedance and Impedance-Driven Instabilities WP 6: Fast Instability Control Feedback WP 7: Electron Cloud WP 8: Power Systems WP 9: Other Collective Effects WP 10: 650 MHz SRF Cavity Design WP 11: Magnets and Supports WP 12: Systems Integration and Availability WP 13: Vacuum System WP 14: Injection and Extraction Systems WP 15: Ion Effects Magnets Technical Group Meeting

  6. WP Interest and Coordination Magnets Technical Group Meeting

  7. Plans for Magnet & PS KOM Presentation I • Overview of RDR Design • Magnet Counts and Types • Review of Conventional Magnets • Design level • Costing Basis • Uncertainty Estimates • Review of Wiggler Design • Closely modeled on CESR-c wiggler design • Cost Extrapolation • Uncertainty Estimates • Areas for optimization and cost reduction • Power System • Design Level • Strings versus individual power supplies • Costing Basis (PS’s in alcoves) • Uncertainty Estimates • Evolution of Design • Distributed Power System • Updated Costing Magnets Technical Group Meeting

  8. Plans for Magnet & PS KOM Presentation II • EDR Planning • Magnets • Define elements of a “magnet design” • Describe the required documentation • Requirements for stable specifications • DR Group is targeting a lattice freeze by 1/1/08 • Design issues: • Interface with other sub-systems (ie, DR WPs) • Particularly the DR vacuum system • Distributed PS 1 Conventional Magnets • Global systems interface (AC, LCW, Controls, Installation,…) • etc… • Interface across Area Systems • Standards (eg, materials and components, interfaces and monitoring,…) • Standardization (ie, minimize overall number of designs) • Hand-off regions • etc… Magnets Technical Group Meeting

  9. Plans for Magnet & PS KOM Presentation III • Issues for specific magnet designs • For example, SC wiggler interface issues with vacuum chambers having EC mitigation and experiencing large synchrotron radiation loads • Aperture and baking requirements • Possible prototyping requirements • etc… • Reliability, Availability, and FMEA Issues Magnets Technical Group Meeting

  10. Plans for Magnet & PS KOM Presentation IV • Power System • Define elements of a “power system design” • Describe the required documentation • Requirements for stable specifications • Again the driving issue is optics and the DR Group is targeting a lattice freeze by 1/1/08 • Also interface issues • Design Issues • Operational specifications (eg, individually controlled magnets) • Interface requirements (communications, control, monitoring) • Bulk and distributed power supply designs • Tunnel environment (eg, radiation and reliability, dissipated power) • etc… • Design Status and Needs • Standard designs versus new or novel elements (eg, need for redundant bi-polar PS development) Magnets Technical Group Meeting

  11. Plans for Magnet & PS KOM Presentation V • Evaluation of completeness based on estimated resources • Discussion of milestones • Discussion of acceptable levels of design for EDR • Discussion of acceptable schedule for EDR • Discussion of acceptable degree of analysis (eg, FMEA) for EDR Magnets Technical Group Meeting

  12. Other Items • Are there other key items that the group feels should be included? • Intend to have draft slides available for review late next week • Allows 1 week for comments and changes Magnets Technical Group Meeting
