Detailed Description

MultipoleTiStraight defines a straight combined function magnet (up to arbitrary multipole component) with fringe fields

Class category: AbsBeamline
$Author: Titus Dascalu, Martin Duy Tat, Chris Rogers

The field is obtained from the scalar potential

\[ V = f_0(x,s) z + f_1 (x,s) \frac{z^3}{3!} + f_2 (x,s) \frac{z^5}{5!} + ... \]

(x,z,s) -> Frenet-Serret local coordinates along the magnet
z -> vertical component
assume mid-plane symmetry
set field on mid-plane -> $ B_z = f_0(x,s) = T(x) \cdot S(s) $
T(x) -> transverse profile; this is a polynomial describing the field expansion on the mid-plane inside the magnet (not in the fringe field); 1st term is the dipole strength, 2nd term is the quadrupole gradient * x, etc.
-> when setting the magnet, one gives the multipole coefficients of this polynomial (i.e. dipole strength, quadrupole gradient, etc.)

----------— example --------------------------------------------—
Setting a combined function magnet with dipole, quadrupole and sextupole components:
$ T(x) = B_0 + B_1 \cdot x + B_2 \cdot x^2 $
user gives $ B_0, B_1, B_2 $
----------— example end ----------------------------------------—

S(s) -> fringe field
recursion -> $ f_n (x,s) = (-1)^n \cdot \sum_{i=0}^{n} C_n^i \cdot T^{(2i)} \cdot S^{(2n-2i)} $
for curved magnets the above recursion is more complicated
$ C_n^i $ -> binomial coeff; $ T^{(n)} $ -> n-th derivative
