Status of the AC Dipole Study. Ryoichi Miyamoto 3/28/2007 LARP Meeting @ Fermilab. Basics. δ. ν. @VBPMB18. ν d. 1 - ν d. 0. 1. @VBPMB21. Driven Oscillation ≠ Natural Oscillation. “Relative” β can be measured Need to be scaled to determine the “absolute” function.

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