  1. Status of the AC Dipole Study Ryoichi Miyamoto 3/28/2007 LARP Meeting @ Fermilab

  2. Basics δ ν @VBPMB18 νd 1-νd 0 1 @VBPMB21

  3. Driven Oscillation ≠ Natural Oscillation • “Relative” β can be measured • Need to be scaled to determine • the “absolute” function.

  4. Courant-Snyder Parameter Measurement@ IP Using CPMs (Sypher’s Scheme) • Gives the scaling to the relative measurement. • β* and waist location are also very important. @ Tevatron’s IPs If x and x’ are known… BPMU BPMD • No magnets • (except detector’s solenoids) • Particles drift • x and x’ can be measured

  5. AC Dipole Version of the Courant-Snyder Parameter Measurement @ IP Using CPMs

  6. Measuredβ

  7. Measuredα

  8. Phase Spaces with Different δ (Backup)
