CERN Pulsed Power Modulators

modulator roadmap
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

development directions
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 )?

collaborations
Collaborations
  • We need to collaborate to create a modulator:

collaborations1
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?
