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 flippersCourtesy 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
