Abstract

This tutorial is tailored for students and postdocs, including those who have no prior exposure to synchrotron experiments. It provides a broad introductory overview of the science one can perform at the ALS with an emphasis on some of the experimental techniques, from spectroscopy to scattering and imaging. Each topic will include a general introduction to the technique(s) and examples of applications highlighting the capabilities of the ALS beamlines.

Anyone can perform experiments at the ALS for free, and access to this facility is through a beamtime proposal process. As such, the lunch discussion session will be about how to become a user of the ALS and obtain beamtime, including guidance about how to write a proposal and how proposals are evaluated. This is the place to ask all the questions you have about a particular technique and how to successfully apply it to your scientific project! Students with no/limited prior synchrotron experience are particularly encouraged to attend.

Finally, to participate in the in-person tour of the synchrotron ring and observe the ongoing ALS-U high coherence upgrade, please wear long pants and closed-toe shoes for the late afternoon tour session. This is a strict safety requirement.
