Isabelle joined the group part way through the spring semester. She is a freshman in the physics department also pursuing a degree in Russian. Her project will be to characterize the optimal parameters for high harmonic generation.

Thank you, Ryan!
Our last group dinner with Ryan! Thank you for all your hard work and contributions to the group. You will be missed, and congratulations on the completion of your post doc!
New Semester, New Faces!
This semester, we welcome three new members to our group!
Our new post doc, Rafaella Georgiou will use X-ray spectroscopy to probe the chemical speciation of paint materials that led to a revolution in the 15th century, namely the transition from tempera to oil painting in Italy that marked the beginning of the great period of Renaissance art and the creation of some of the most revered masterpieces of all time.
We also welcome two new graduate students, Sophie Vogelsang and Caleb Robinson. Sophie recently graduated from Vanderbilt University with a BA in Chemistry and History of Art and completed her undergraduate thesis in Dr. Lauren Buchanan’s research group. Caleb graduated from Rice University in May 2022 with his Bachelor of Science in physics and a minor in mathematics. As a member of the Killian Research Group at Rice, he wrote his senior thesis on implementing a new source of 422 nm laser light used for imaging ultracold strontium plasmas.
Wisconsin Science Festival!
Our group participated in this years Wisconsin Science Festival! We had a booth at the Discovery Expo and Science on the Square. We had many wonderful demos and a lot of fun sharing our knowledge with our community here in Madison!
Group Hike at Devil’s Lake State Park
With numbered nice days left in the year, our group took a trip out to Devil’s Lake State Park to see the Fall colors! There was lots of hiking, swimming, food, and most importantly laughs. More adventures to come for the Bergmann group!
Welcome, new undergraduate student Muneeza Munawar!
Muneeza joined the group at during the Fall semester of 2022. She is a junior majoring in physics and astronomy.
Joint Postdoc Position in Nonlinear X-ray Science at University of Wisconsin-Madison and Stanford University/SLAC National Accelerator Laboratory
Welcome, rotation student Sophie Vogelsang!
Sophie Vogelsang is a rotating chemistry student. She recently graduated from Vanderbilt University with a BA in Chemistry and History of Art and completed her undergraduate thesis in Dr. Lauren Buchanan’s research group.
LCLS Summer Interns Poster Session Award
One of our talented undergraduates students, Noah Welke, spent the summer at SLAC National Accelerator Laboratory as an intern. There, he did research with Alex Halavanau developing a solid gain medium for XLO at CXI. At the end of the summer, his hard work was awarded well with first place at the LCLS Summer Internship Poster Session! Congratulations Noah, we are very proud of you!

First XUV Spectrum!
We successfully produced our first high harmonic spectrum! What is pictured is a spectrum of our source, which is an 800nm beam, up-converted, using neon, gas through high harmonic generation (HHG) to create an extreme-ultraviolet beam (XUV)!
