Relativistic Stern-Gerlach Deflection: Hamiltonian Formulation
S. R. Mane
A Hamiltonian formalism is employed to elucidate the effects of the Stern-Gerlach force on beams of relativistic spin-polarized particles, for passage through a localized region wi…
Polarization at TLEP/FCC-ee: ideas and estimates
S. R. Mane
I examine various ideas for radiative polarization at TLEP/FCC-ee and formulate some estimates for the polarization buildup time and the asymptotic polarization. Using wigglers, a…
Equation for spin decoherence rate in an all-electric ring
S. R. Mane
There is a quantitative error in the derivation for the spin decoherence rate by Talman in IPAC2012. The crucial point is a subtle confusion between the concept of `longitudinal' a…
Orbit and spin tracking in a radial electric field
S R Mane
I derive an expression for the spin decoherence rate for a smooth focusing electrostatic ring with a radial electric field. The answer contains some salutary lessons about spin dec…
Comment on "rf Wien filter in an electric dipole moment storage ring: The "partially frozen spin'' effect''
S. R. Mane
The Jacobi-Anger identity is employed to quantify the findings of Morse, Orlov and Semertzidis [1]. The secular term in the longitudinal spin component is proportional to a Bessel…
