Returns:

surf_list – List of Magnet Surface and Air Surface on the slot

Return type:

list

check()

Check that the HoleM53 object is correct

Parameters:

self (HoleM53) – A HoleM53 object

Return type:

None

Raises:

Parameters:

  • self (HoleM53) – a HoleM53 object

  • is_north (True) – True: comp north magnetization, else add pi [rad]

comp_W5()

Compute the W5 width of the hole (cf schematics)

Parameters:

self (HoleM53) – a HoleM53 object

Returns:

W5 – Cf schematics [m]

Return type:

Raises:

Slot53InterError – ERROR: Slot 53, Can’t find Z11 coordinates

has_magnet()

Return if the Hole has magnets

Parameters:

self (HoleM53) – A HoleM53 object

Returns:

has_magnet – True if the magnets are not None

Return type:

bool

  • is_add_schematics (bool) – True to display the schematics information (W0, H0…)

  • is_add_main_line (bool) – True to display “main lines” (slot opening and 0x axis)

  • type_add_active (int) – 0: No active surface, 1: active surface as winding, 2: active surface as magnet

  • save_path (str) – full path including folder, name and extension of the file to save if save_path is not None

  • is_show_fig (bool) – To call show at the end of the method

  • fig (Matplotlib.figure.Figure) – existing figure to use if None create a new one
