Magnet Geometry

one_of_each_base.gmad

A base file that’s used (include one_of_each_base.gmad) by many examples in this directory. It’s loosely based on the one of each example in layout and contains one of each of the magnetic elements in BDSIM. Each example demonstrates a different geometry possible.

1_cylindrical.gmad

Key code:

magnetGeometryType="cylindrical";

This example uses the sequence of magnets defined in one_of_each_base.gmad and ensures that they have cylindrical geometry. This is a little redundant as the default is cylindrical.

How to run:

bdsim --file=1_cylindrical.gmad

../_images/1_cylindrical.png

2_poles_circular.gmad

Key code:

magnetGeometryType="polescircular";

As above but with poled geometry and a circular yoke.

How to run:

bdsim --file=2_poles_circular.gmad

../_images/2_poles_circular.png

3_poles_square.gmad

Key code:

magnetGeometryType="polessquare";

As above but with poled geometry and a square yoke.

How to run:

bdsim --file=3_poles_square.gmad

../_images/3_poles_square.png

4_poles_face.gmad

Key code:

magnetGeometryType="polesfacet";

As above but with poled geometry and a square yoke rotated by 45 degrees.

How to run:

bdsim --file=4_poles_facet.gmad

../_images/4_poles_facet.png

5_poles_face_crop.gmad

Key code:

magnetGeometryType="polesfacetcrop";

As above but with poled geometry and a square yoke rotated by 45 degrees. Additionally, the corner edges are cropped giving the yoke, \(n x 2\) edges, where \(n\) is the number of poles the magnet has.

How to run:

bdsim --file=5_poles_facet_crop.gmad

../_images/5_poles_facet_crop.png

6_lhcleft.gmad & 7_lhcright.gmad

Key code:

magnetGeometryType="lhcleft";
magnetGeometryType="lhcright";

LHC cyrogenic magnet for dipoles and quadrupoles. Given the two beam nature of the LHC, the magnet is either offset to the right or two the left dictating the ‘active’ beam pipe.

../_images/7_lhcleft.png

8_none.gmad

Key code:

magnetGeometryType="none";

No magnet outer geometry is built around the beam pipe - only the beam pipe exists.

9_coils.gmad

A test with carefully split and spaced quadrupoles to test the automatic choice to place or not the coils at the end of a magnet.
