This a thick element to define a constant focusing constant bent channel.

Element name,	1st number,	2nd number,	3rd number	4th number,	5th number,	6th number,	7th number,
UCHUBEND,	length [m],	kx [m^[-n-1}],	ky [m^{-n-1}}]	Rx [m],	Ry [m],	half horizontal beam pipe [m],	half vertical beam pipe [m]

Here kx,ky are the horizontal and vertical constant focusing strength; Rx,Ry are the radiuses of curvature in x and y.

The data of this element are stored in the matrix alat(n,m). The first index in alat identifies the lattice element as found in the sequence of elements loaded from the lattice file. The number of elements is NELMAX. In the variable alength is stored the lattice length.
