Description

Right now, our User Manual is neutron centric. BornAgain claims to support GISAXS and GISANS equally well!

History

#1 Updated by wuttke over 5 years ago

  • Priority changed from Normal to High

Derive the wave equation with and without polarization for neutrons and for electromagnetic waves, and choose a common notation for both kinds of radiation. Search the literature for best practice examples, and provide references in the text.

This will lay the foundations for implementing the polarization factors for X-rays, #31.

#2 Updated by wuttke over 5 years ago

  • Subject changed from Documentation should treat X-rays and neutrons on equal footing to Derive scalar and polarized wave equation to treat X-rays and neutrons on an equal footing.
  • Description updated (diff)

#3 Updated by wuttke over 5 years ago

  • Subject changed from Derive scalar and polarized wave equation to treat X-rays and neutrons on an equal footing. to Derive scalar and polarized wave equation for both X-rays and neutrons, and choose appropriate notation.

Commit e73cef8 adds a manual section on X-ray propagation.

Still to do:
  • derive polarization factors for X-rays
  • revise polarized-neutrons chapter

Reference paper makes the formalism as compact as possible. For more detailed investigations, it turns out that it is better to treat polarized neutrons and X-rays separately. Documents continue to evolve in our ba-intern/theory folder.
