Beam Pipes
==========

1_circular.gmad
---------------

A 0.2m section of circular beam pipe - nothing particularly interesting.

How to run::
  
  bdsim --file=1_circular.gmad

.. figure:: 1_circular.png
	    :width: 40%

2_rectangular.gmad
------------------

A 0.2m section of rectangular beam pipe.

How to run::
  
  bdsim --file=2_rectangular.gmad

.. figure:: 2_rectangular.png
	    :width: 50%

3_elliptical.gmad
-----------------

A 0.2m section of elliptical beam pipe. The definition of the drift overrides
the default parameter of :code:`beampipeThickness` here.

How to run::
  
  bdsim --file=3_elliptical.gmad

.. figure:: 3_elliptical.png
	    :width: 30%

4_lhc.gmad
----------

A 0.2m section of lhc-style beam pipe. The definition of the drift overrides
the default parameter of :code:`beampipeThickness` here. Additionally, :code:`aper1`,
in the definition of the drift `d1` overrides the general (degenerate)
:code:`beampipeRadius` option in options.gmad.

How to run::
  
  bdsim --file=4_lhc.gmad

.. figure:: 4_lhc.png
	    :width: 40%


5_lhcdetailed.gmad
------------------

Similary to 4), a 0.2m section of lhc-style beam pipe but with the
more detailed lhc aperture model. 

How to run::
  
  bdsim --file=5_lhcdetailed.gmad

.. figure:: 5_lhcdetailed.png
	    :width: 40%

6_rectellipse.gmad
------------------

A 0.2m section of rectangular-ellipse beam pipe. This is composed of the
intersection of a rectangle and an ellipse, unlike the lhc-style beam pipe
that is the intersection of a rectangle with a circle.

How to run::
  
  bdsim --file=5_lhcdetailed.gmad

.. figure:: 6_rectellipse.png
	    :width: 40%

7_racetrack.gmad
----------------

A small section of beam pipe with a MADX racetrack aperture style. This is
a rectangle with circularly rounded corners.

How to run::

  bdsim --file=7_racetrack.gmad

.. figure:: 7_racetrack.png
	    :width: 40%


8_octagonal.gmad
----------------

A small section of beam pipe with an octagonal aperture style. This is
a rectangle with flat cut corners.

How to run::

  bdsim --file=8_octagonal.gmad

.. figure:: 8_octagonal.png
	    :width: 40%


9_circularvacuum.gmad
---------------------

Circular vacuum doesn't make any beam pipe and the vacuum is by default
invisible so there is nothing to visualise. However, this is useful for
visualising the trajectories of the beam.

How to run::

  bdsim --file=9_circularvacuum.gmad

10_clicpcl.gmad
---------------

A small section of CLIC post collision line beam pipe.

How to run::

  bdsim --file=10_clicpcl.gmad


.. figure:: 10_clicpcl.png
	    :width: 40%

12_pointsfile.gmad
------------------

A custom beam pipe defined by :code:`12_points.dat`.

.. figure:: 12_pointsfile.png
	    :width: 50%

16_rhombus.gmad
---------------

A few diffrent rhombus shapes.

.. figure:: 16_rhombus.png
