2025 User Meeting Workshops & Tutorials

The 2025 User Meeting will take place in person August 11–13 at the DoubleTree by Hilton Hotel Berkeley Marina in Berkeley, CA.

In addition to the always-popular science workshops presenting the latest scientific findings and technical advances, the ALS User Meeting offers tutorials geared towards introducing new and seasoned users to various techniques, tools, and instrumentation.

Principles and Calculations of X-Ray Core-Level Spectroscopy  |  Tutorial

Tuesday, August 12, 1:30–5:00 pm, and Wednesday, August 13, 8:00 am–12:00 pm

Organizer: Wanli Yang

Abstract

This tutorial, presented by Prof. Frank de Groot, offers an in-depth exploration of various synchrotron-based X-ray core-level spectroscopy. The tutorial covers the principles, theoretical understanding, and calculations. The topics include X-ray absorption spectroscopy (XAS), X-ray emission spectroscopy (XES), X-ray photoelectron spectroscopy (XPS), X-Ray Magnetic Circular Dichroism (XMCD), and resonant inelastic X-ray scattering (RIXS), with detailed insights into their physical origins and theoretical interpretations.

Prof. de Groot, as an author of Core Level Spectroscopy of Solids (CRC Press, 2008), brings decades of expertise in both research and teaching. The tutorial spans a wide range of model systems and delves into foundational theories focusing on charge transfer multiplet model and Density Functional Theory + multiplets. Hands-on computational sessions will be offered. CRISPY/QUANTY and CTM4XAS will be used, but attendees can also use RAS-SCF, ORCA, EDRIXS, Xclaim, etc.

Note this comprehensive workshop includes two parts: in-person lectures and hands-on sessions during the UM, followed by two hybrid sessions for (only) registered attendees after UM with Zoom. However, the two sessions during UM are stand-alone, focusing on XAS. We highly suggest attending the full lecture that covers other spectroscopic techniques. The event culminates with a lively talk, “20 Ways to Measure XAS,” promising to leave participants both informed and entertained.
