Description
We made software to simulate Larmor precession in a setup for SESANS with adiabatic/RF flippers in magnets, existing at PNPI. The final polarisation of a divergent "gribbon beam" of height 2 cm is calculated as a function of λ. For λ = 6 Å, flippers 56 cm apart and RF frequency 1 MHz we find spin-echo length δ = 0.9 δm. We show numerically, how λ is converted to δ. Extension to δ = 20 δm is realistic.
