Experimental Peak Intensity Analysis for CXLS at BioXFEL - Poster
Title: "Peak Intensity Analysis for Serial Femtosecond Crystallography Experiments at the Compact X-ray Light Source."
Authors: Kurth, A. M., Botha, S.
Affiliations: CXFEL Labs Biodesign Institute, Arizona State University; Department of Physics, Arizona State University
Abstract: This research introduces innovative Bragg peak integration methods to advance peak intensity analysis in X-ray crystallography, crucial for accurate structure determination. The Compact X-ray light source (CXLS) will produce femtosecond duration X-ray pulses, allowing the collection of “diffraction before destruction” data. However, the flux will be limited compared to traditional full-scale X-ray free electron laser facilities, warranting the development of unique data analysis tools to fully exploit the unique capabilities of these sources for macromolecular crystallography. By improving the differentiation between signal and noise, coupled with a novel data collection scheme, our approach will enable experiments at the compact X-ray light source at Arizona State University.

Enhancing X-ray Peakfinding Through Deep Learning - Poster
Title: "Enhancing X-ray Peakfinding Through Deep Learning at the Compact X-ray Light Source (CXLS), Arizona State University"

Affiliations: The Biodesign Beus CXFEL Laboratory, Arizona State University; Department of Physics, Arizona State University
Abstract: This paper explores the application of deep learning techniques at Arizona State University's (ASU) Compact X-ray Light Source (CXLS) to analyze experimental data from various modalities, primarily focusing on X-ray crystallography using the Dectris Eiger 4M detector. Traditional methods of predicting photon energy and sample-detector distance are challenged by dynamic scattering, intrinsic noise, and the CXLS low flux X-ray beam, prompting the need for more advanced solutions. Utilizing the CrystFEL software, we simulate diffraction images for protein 1IC6.pdb across a matrix of nine variable combinations involving photon energies and camera length. Our approach employs convolutional neural networks (CNNs), testing various architectures for binary classification of peak detection and prediction of experimental parameters. The scope of this research wishes to further expand this with modifications in the architecture to accommodate for spectroscopy data, although this is beyond the extent of this manuscript. By integrating different experimental conditions, we anticipate broader applications and improved experimental outcomes.
