/Using SANS software

Overview:

• Regarding BornAgain:
  • Need a set of prototype models (check what is on the BA webpage) - especially for inexperienced users
  • This should include a very detailed description about its physical limitations, directly implemented into BA sending error messages if overgone.
  • Further good features to implement: (i) intensity w.r.t. direct beam, w.r.t multiple scattering background, w.r.t. general expected background (according to experience + commissioning).

Detailed notes group 4:

• A set of prototype models for several example systems is really great piece of help for inexperienced users of BornAgain.
• However, it will be even more helpful if every model describes its physical limitations - in other words, a user should be warned if he is choosing a value of a parameter which breaks the validity of the theory behind this model (for example size of the particles, particle distribution over the surface etc). So that a user do not consider unrealistic models.
• On the top of this it will be nice if a user can estimate
  • intensity of GISANS signal in respect to the direct beam
  • in respect to the multiple scattering background calculated by BornAgain
  • in respect to a general background expected in the experiment (basing on the previous experience with similar sample environment, materials, guide halls etc).

• Sample environment should be continuously developed the knowledge is shared inside of the community.
