Description

The virtual course is planned to run on four days (Tuesdays and Thursdays), from approximately 09:00 to 16:00 GMT each day, divided into two sessions, attended via Zoom. Each session will consist of a lecture, followed by demonstrations and hands-on guided practicals.
This training school will have a varied content suitable for novices and more experienced users (not limited to PhD students):

principles of reflectometry, including polarised neutron reflectometry
working principles of time-of-flight reflectometers (including a virtual guided tour)
data reduction principles
reflectivity fitting theory (model building approaches, fitting strategies etc)
error analysis techniques for reflectivity data
case studies for different science areas and using different fitting software
live interactive demonstrations and exercises using online resources,
such as IDAaaS and Google Colab
live help and advice for users, who have already collected reflectivity data
