Barty Group graduate student Leslie Heid has received an NSF GRFP Honorable Mention for her proposal titled “Laser Compton Scattering Cavity Optimization.” Leslie will be building and optimizing a laser recirculation cavity that she hopes will be used to improve the brightness of Laser-Compton Scattering (LCS) sources.

Her reviewers made very positive comments about her application: “This applicant has the trifecta of science skill, perseverance, and broader understanding that are what this program is looking for.” “Remarkable candidate! In spite of all difficulties, this applicant was able to keep focus on future and develop a very strong interest in science.”

Congratulations Leslie!

For his paper Low-Dose, Dual-Energy Medical Imaging of Gadolinium Contrast Agents Using Laser-Compton X-ray Sources, Barty Group grad student Trevor Reutershan won the Optica Student Paper Award for the Compact (EUV and X-Ray) Light Sources (EUVXRAY) category at the 2022 High-Brightness Sources and Light-Driven Interactions Congress. According to the congress’s website, the Program Committee members made their winners selection “based on content quality, value to the technical community of interest, and the students’ presentation skills.”

Great job Trevor!

Last week, Barty Group members Kyle Chesnut, Haytham Effarah, Trevor Reutershan, and Professor Chris Barty presented at the 2022 High-Brightness Sources and Light Driven Interactions Congress, hosted by Optica. The congress was held in Budapest, Hungary this year.

“Our group had a very strong showing overall, especially in the EUV/X-ray Sessions. It was noted by a number of different people and I think we made quite a splash among the Optica hosts. Haytham’s session that he presided over was recognized as very well run.”- Kyle Chesnut

In the latest issue of Applied Optics, Barty Group members Trevor Reutershan, Haytham Effarah, and Professor Barty, along with former Barty Group post-doc Agnese Lagzda, investigate gadolinium-based K-edge subtraction imaging via laser Compton sources for mammographies. They calculate that this imaging technique will significantly increase contrast and significantly decrease dose. Click here to learn more.

In the latest edition of Applied Optics, Barty Group members Haytham Effarah, Trevor Reutershan, and Professor Barty, along with collaborators from Lumitron Technologies (including former Barty Group post-doc Agnese Lagzda), report on a highly efficient method for modeling LCS outputs. The approach is up to 200 times less computationally expensive than direct simulations of LCS. Click here to learn more.

In the latest issue of Applied Optics, Professor Barty and external collaborators demonstrate the ability to detect isotopes with microgram accuracy at long distances from the sample. This is enabled by NRF via quasi-monochromatic, high-energy photon beams. The article is an Editor’s Pick! Click here for the article.
