Issue1177 debug

[Didou09]

Main changes:

• coll.add_rays_from_diagnostic(key_cam=str or list) implemented
• spectro.spectral_range2():
  • restructured with _check.py, _compute.py and _plot.py
  • More robust vs inputs
  • More explicit keywords
  • Allows for multiple combinations of aperture, crystal, camera
  • Ray-tracing now focuses on lamb0, lamb0_min and lamb0_max
  • Markers now show which components is limiting (aperture with semi_angle_max, crystal length or camera)
• Magnetic sheilding:
  • physics_tools.magnetic.shielding.single() operational
  • physics_tools.magnetic.shielding.double() exists

Issues:

Fixes, in devel:

• Minor debug #1177

Magnetic shielding routines should be merge into a single one handling {transverse + axial} for multiple layers
=> #1179 opened

Examples:

spectro.spectral_range_2d()

physics_tools.magnetic.shielding.single()

dout, dax = tf.physics_tools.magnetic.shielding.single(
    diam_inner_ref=0.15, 
    diam_outer=0.15 + np.linspace(0.001, 0.05, 31), 
    diam_outer_ref=0.16, 
    Bin_lim_T=1e-3,
)
