16.4 Compressor lattice coordinates

Figure 16.2 has been provided by Steve Wesseln (Fermilab), version from the 15$^{th}$ June 2009.

Figure 16.2: Dipoles hard edge coordinates for NML compressor lattice

Table 16.3 reference the coordinates of the dipoles where the origin is taken at the cathode. See figure 3 for convention of notations. The column $x$ and $z$ corresponds to the real geometry(cf figure 16.2) expressed with respect to the entrance point in the first dipole. Nevertheless, in previous simulations from Yin-e Sun[41] a dipole length of 230 mm has been used. We thus add an offset of $dz=\pm15$mm to the longitudinal coordinate to satisfy this condition. The center of the first dipole being at $z=11.7655$m, we write the final coordinates with respect to the cathod in the last column of the table.
