beam section (mandatory)

Here we define the main properties of the beam at the entrance of the linac. Note that with TraceWin, most of these properties are defined within its own .ini file. The units must be consistent with LightWin’s system of units, see also Units and conventions.

Format for the sigma entry:

sigma = [
   [ 1e-6, -2e-7,  0e+0, 0e+0,  0e+0, 0e+0],
   [-2e-7,  8e-7,  0e+0, 0e+0,  0e+0, 0e+0],
   [ 0e+0,  0e+0, -2e-7, 8e-7,  0e+0, 0e+0],
   [ 0e+0,  0e+0, -2e-7, 8e-7,  0e+0, 0e+0],
   [ 0e+0,  0e+0,  0e+0, 0e+0, -2e-7, 8e-7],
   [ 0e+0,  0e+0,  0e+0, 0e+0, -2e-7, 8e-7]
