  1. CERN modulator R&DPulsed High Power Modulators 09/03/2010 CERN Pulsed Power Modulators

  2. Modulator Roadmap • The CERN Electrical Power Converter group is starting a study on high-power modulators to investigate • Appropriate modulator technologies • Detailed design of critical sub-systems • Prototype evaluation of key sub-systems • Objectives • Propose well evaluated technical solutions for future accelerator requirements, in particular HP-SPL and CLIC • Provide estimates of cost, volume and other pertinent data • The project is structured such that a working modulator prototype for SPL or CLIC could be envisaged for ~2014 CERN Pulsed Power Modulators

  3. Development directions • Appropriate modulator technologies • Detailed design of critical sub-systems • Prototype evaluation of key sub-systems • Pulse transformers • HV Transformers • Pulse-to-pulse stability • Ripple characterisation (HF and LF) and compensation • Cost effective chargers • ‘Most efficient’ topologies (eg resonant topologies )? CERN Pulsed Power Modulators

  4. R&D Planning… CERN Pulsed Power Modulators

  5. Collaborations • We need to collaborate to create a modulator: CERN Pulsed Power Modulators

  6. Collaborations • Partnerships for medium term – what could be envisaged? • Contract between EPC and Researcher OR CERN and University? • Can multiple partnerships work together (eg Nottingham has experience of SNS and resonant topologies)? • Partial funding from national bodies? CERN Pulsed Power Modulators

  7. R&D Planning… CERN Pulsed Power Modulators

  8. Objectives • Select topology and justify decision: May 2010 • Dimensioning model for 1 (or more) topologies: June 2010 • For main components • Full simulation of selected topology: November 2010 • Design of main magnetic component(s): Oct 2010 • Design of main power electronics: May 2011 • Reduced power prototype: Oct 2011 CERN Pulsed Power Modulators

  9. Objectives - documentation • Internal papers • Pulsed modulator topologies (Draft: May 2010) • High Voltage Pulse Transformers (Draft: May2010) • Models for dimensioning pulsed power modulators (Draft: May 2010) • … • Conference paper(s) at one (or more) of: • PAC 2011, New York, USA, 28/3 — 1/4 • IPAC 2011, Spain, 1/9 – 6/9 • EPE 2011, UK, 30/8 – 2/9; Abstract: 1/11/2010 CERN Pulsed Power Modulators
