We are pleased to announce a 5-day in-person “Spectroscopy Masterclass” in theoretical spectroscopy at Rutherford Appleton Laboratory, UK, 1-5 September 2025.

The school will teach the calculation of different spectroscopies including core (such as XAS, XMCD), valence band (ARPES) and magnetic excitations (as probed by INS) using first-principles electronic structure codes: SPR-KKR, MsSpec and Questaal.

Lectures will provide an introduction to the theory as well as a high-level overview of the current state of the art in spectroscopy modelling.  Afternoons will be dedicated to practical, hands-on teaching sessions designed for newcomers to electronic structure theory.  The aim of the practical sessions is to enable experimentalists to carry out calculations independently.

The final afternoon is dedicated to open discussion on how best to provide theory support at the large scale facilities.

The event is funded as a CECAM Flagship School, with sponsorship from the Ada Lovelace Centre and the UK’s CCP9 network.  There is a registration fee of £100 which covers accommodation.  Lunch and the conference dinner are provided.
