Agenda:

13:00-13:05- Introduction: Dr. Tom Penfold, Newcastle University

13:05- 13:45- Presentation: Dr. Mirian Garcia-Fernandez, Diamond Light Source

13:45-14:00- Q&A

Topics for Discussion:

The I21 beamline at Diamond Light Source is a next-generation soft x-ray Resonant Inelastic X-ray Scattering (RIXS) beamline at Diamond Light Source in the UK. The beamline covers an energy range from 250 to 1500 eV with a planned upgrade up to 3000 eV. First users were welcomed in September 2017 and the beamline is currently operational in optimization mode.

The scientific program of the beamline focuses on the study of low-energy (< 0.5 eV) electronic and lattice excitations in solid state magnetic materials. Through the early X-ray commissioning and user operations, the energy resolution of about 35 meV at Cu L-edge (930 eV) and about 15 meV at Oxygen K-edge (532 eV) was obtained with high photon flux.

In this talk, Mirian will introduce soft x-ray resonant scattering (elastic and inelastic) followed by a discussion of the possibilities at I21 for the study of electronic, magnetic and lattice dynamics, particularly in strongly correlated electron systems.

Speaker Bio:

Dr. Mirian Garcia-Fernandez, I21 RIXS Beamline Scientist, Diamond Light Source

Dr. Mirian Garcia-Fernandez completed her PhD at the Swiss Light Source, followed by a postdoc with the group of Prof. Dr. Philip Aebi in the University of Fribourg to study strongly correlated electron system with photoemission spectroscopy. Her second postdoc was with the group of John Hill at Brookhaven National Lab in New York, where she was responsible for a project that focused on extending the use of resonant scattering to the nano regime by implementing the use of zone plates.

After the experience working with zone plates and performing experiments in the nano regime Mirian grew interested in this field of physics and in February 2014 she joined the I13 - coherence and imaging beamline in Diamond as Senior Support Scientist.

In 2015, Mirian moved to the I21-RIXS beamline in Diamond to be involved in its design and construction with the rest of the team headed by Dr. Kejin Zhou. In 2019 after the completion of the beamline construction she was promoted to I21 Beamline Scientist where she continues to develop her interest in studying the properties of strongly correlated electron systems.
