An Assessment of Phase Space Engineering

Discussion Leader: Herb Berk

 

Issues in phase space engineering:


A. Knowing where the alpha particle are, to determine heating properties and ignition scenarios
  1. Accounting for classical confinement with field errors
  2. Measuring their population under classical and fluctuating conditions
  3. Comparing with calculations for ignition scenarios

B. Using alpha particle properties for diagnostic purposes
(e.g., knock-on effect, double charge exchange, escape spectra, etc.)

C. Self-consistent plasma effects as a diagnostic
  1. Ion cyclotron emission
  2. TAE and other Alfven signatures
  3. Fishbone signatures

D. Active intervention using alpha particle effects
  1. Suppression of saw-teeth
  2. Mechanisms to implement energy channelling
  3. Waves and "buckets" to control He build-up
  4. Using instabilities to control burn characteristics

E. Additional suggestions appreciated
