Microtron Dipole Magnet

Post by golge » 10 Apr 2009, 10:43

Dear Michael

Is there any way to implement/simulate a microtron type dipole magnet in elegant? I am attaching a figure to show you what I mean..In contrast to entering to the dipole pole face in a conventional way imagine that the beam enters from the long side of the dipole, and where it leaves from the very same long side..

Serkan,

You can simulate this using SBEN or CSBEND elements. However, you'll need to manually compute the arc length for each pass. To elegant, this is just a dipole with very large edge angles: E1=E2=(pi-theta)/2, where theta>0 is the bending angle.

If the dipole has significant fringe fields, you could use instead the NIBEND element, which is a Numerically Integrated Bend with extended fringe field. You'll need to compute the edge integral (FINT) as described on the NIBEND manual page. This is probably a good idea if the beam comes in at a shallow angle.
