Monochromators

One of the first elements we encounter along the beamline is the monochromator.

Here's an article describing how to compute the flux following a monochromator:

Beamline modeling

My last post was about codes for modeling electron beams and x-rays.  As of recently, there is now a new tool for beamline modeling.  Its called Sirepo.

One can model many different beamlines with this code.

Here are the beamlines at the ALS, for example

Here are the beamlines at the NSLS-II
