Transform3d

1_rotation.gmad

A drift, followed by a transform3d that rotates about the beam axis, then followed by another drift and a quadrupole. The drifts have rectangular beam pipes so the rotation caused by the transform3d can be seen. The quadrupole is therefore also rotated. A sampler placed at the end will also be rotated with respect to global coordinates as the transform3d permanently rotates the coordinate axes.

How to run:

bdsim --file=1_rotation.gmad

2_rotation_with_bends.gmad

A small machine with some bends, quadrupoles, a sextupole and collimator. This is used to demonstrate the rotation of coordinates that transform3d has on the beam line and demonstrates a method to create vertical bends.

How to run:

bdsim --file=2_rotation_with_bends.gmad
