PTC: Polymorphic Tracking Code (Etienne Forest) • Powerful orbit tracking and analysis tools • Spin subroutines (2009) • Invariant spin field (ISF) via • Normal form • Stroboscopic average • Resonance strengths • Partial derivatives n/px, n/py , n/ • One-resonance Normal Form (Computes directly the input to the Froissart-Stora formula) • Includes spin flippers Courtesy of Dr. Sateesh Mane
Example: MIT-Bates South Hall Ring • Polarized electrons 850 MeV • Internal gas jet target • Siberian Snake(superconducting solenoid) • Spin flipper • Resonance strength n/px • Linear response theory • S R Mane Nucl. Inst. Meth A 601 (2009) 256-263 • Verify using PTC Perfect Match (next slide) Courtesy of Dr. Sateesh Mane
