FACET2-S2E: Start-to-end simulations of the FACET-II beamline
Nathan Majernik, Frederick Cropp, Claudio Emma +1
FACET2-S2E is a Python package for start-to-end simulations of the Facility for Advanced Accelerator Experimental Tests-II (FACET-II), a US Department of Energy National User Facil…
Relativistic ultrafast electron diffraction at high repetition rates
K. M. Siddiqui, D. B. Durham, F. Cropp +17
The ability to resolve the dynamics of matter on its native temporal and spatial scales constitutes a key challenge and convergent theme across chemistry, biology, and materials sc…
Virtual-Diagnostic-Based Time Stamping for Ultrafast Electron Diffraction
Frederick Cropp, Lauren Moos, Alexander Scheinker +6
In this work, non-destructive virtual diagnostics are applied to retrieve the electron beam time of arrival and energy in a relativistic ultrafast electron diffraction (UED) beamli…
Adaptive Latent Space Tuning for Non-Stationary Distributions
Alexander Scheinker, Frederick Cropp, Sergio Paiagua +1
Powerful deep learning tools, such as convolutional neural networks (CNN), are able to learn the input-output relationships of large complicated systems directly from data. Encoder…
Adaptive deep learning for time-varying systems with hidden parameters: Predicting changing input beam distributions of compact particle accelerators
Alexander Scheinker, Frederick Cropp, Sergio Paiagua +1
Machine learning (ML) tools such as encoder-decoder deep convolutional neural networks (CNN) are able to extract relationships between inputs and outputs of large complex systems d…
Ultrafast optical melting of trimer superstructure in layered 1T'-TaTe2
Khalid M. Siddiqui, Daniel B. Durham, Frederick Cropp +12
Quasi-two-dimensional transition-metal dichalcogenides are a key platform for exploring emergent nanoscale phenomena arising from complex interactions. Access to the underlying deg…
Analysis of Skew Quadrupole Compensation in RF-Photoinjectors
P. Denham, F. Cropp, P. Musumeci
In this paper, we present a detailed analysis of the effects of quadrupole components in radiofrequency (RF) photoinjectors, which could occur either in the RF cavity or in the gun…
Mapping Photocathode Quantum Efficiency with Ghost Imaging
K. Kabra, S. Li, F. Cropp +3
Measuring the quantum efficiency (QE) map of a photocathode injector typically requires laser scanning, an invasive operation that involves modifying the injector laser focus and r…
