Presentation Transcript

  1. AC Dipole optimization* Eric Prebys *written up in BEAM-DOCS-2925-v1

  2. Concept • Considerations • High frequency: 1/(2*1.7 msec) ~ 300 kHz • Minimize power supply cost and complexity • Optimize stored energy • Maximize Q

  3. Amplitude requirement At collimator:

  4. At magnet Phase space (live window t): Full amplitude:

  5. Magnet Parameters • Angular amplitude: • Width: • Field: • Gap (minimum waist):

  6. Minimizing Stored Energy Falls with bx For a particularbx, there is an optimum length L0: For which the optimized parameters are:

  7. Non-optimum lengths • Optimum length impractical for large bx • Luckily, parameters weak function of length

  8. Peak Field and Stored Energy • Use A=50p mm-mr, t=200 ns

  9. Magnet Aperture

  10. Proposed Parameters for Development
