Variational Autoencoders for Noise Reduction in Industrial LLRF Systems
J. P. Edelen, M. J. Henderson, J. Einstein-Curtis +3
Industrial particle accelerators inherently operate in much dirtier environments than typical research accelerators. This leads to an increase in noise both in the RF system and in…
Anomaly Detection in Particle Accelerators using Autoencoders
Jonathan P. Edelen, Nathan M. Cook
The application of machine learning techniques for anomaly detection in particle accelerators has gained popularity in recent years. These efforts have ranged from the analysis of…
Propagation of partially coherent radiation using Wigner functions
Boaz Nash, Nicholas Goldring, Jonathan Edelen +2
Undulator radiation from synchrotron light sources must be transported down a beamline from the source to the sample. A partially coherent photon beam may be represented in phase s…
A Vlasov Algorithm Derived from Phase Space Conservation
Jonathan P. Edelen, Stephen D. Webb
Existing approaches to solving the Vlasov equation treat the system as a partial differential equation on a phase space grid, and track in either an Eulerian, Lagrangian, or semi-L…
Opportunities in Machine Learning for Particle Accelerators
Auralee Edelen, Christopher Mayes, Daniel Bowring +10
Machine learning (ML) is a subfield of artificial intelligence. The term applies broadly to a collection of computational algorithms and techniques that train systems from raw data…
PIP-II Injector Test Warm Front End: Commissioning Update
L. Prost, R. Andrews, C. Baffes +19
The Warm Front End (WFE) of the Proton Improvement Plan II Injector Test at Fermilab has been constructed to its full length. It includes a 15-mA DC, 30-keV H- ion source, a 2 m-lo…
Commissioning And First Results From The Fermilab Cryomodule Test Stand
E. R. Harms, M. Awida, C. Baffes +34
A new test stand dedicated to Superconducting Radiofrequency (SRF) cryomodule testing, CMTS1, has been commissioned and is now in operation at Fermilab. The first device to be cool…
Adaptive beam loading compensation in room temperature bunching cavities
J. P. Edelen, B. E. Chase, E. Cullerton +1
In this paper we present the design, simulation, and proof of principle results of an optimization based adaptive feed-forward algorithm for beam-loading compensation in a high imp…
Automatic phase calibration for RF cavities using beam-loading signals
J. P. Edelen, B. E. Chase
Precise calibration of the cavity phase signals is necessary for the operation of any particle accelerator. For many systems this requires human in the loop adjustments based on me…
Status of the warm front end of PIP-II injector test
A. Shemyakin, M. Alvarez, R. Andrews +15
The Proton Improvement Plan II (PIP-II) at Fermilab is a program of upgrades to the injection complex. At its core is the design and construction of a CW compatible, pulsed H- SRF…
Low Level RF Control for the PIP-II Accelerator
J. P. Edelen, B. E. Chase, E. Cullerton +9
The PIP-II accelerator is a proposed upgrade to the Fermilab accelerator complex that will replace the existing, 400 MeV room temperature LINAC with an 800 MeV superconducting LINA…
Current transmission and nonlinear effects in un-gated thermionic cathode RF guns
J. P. Edelen, J. R. Harris
Un-gated thermionic cathode RF guns are well known as a robust source of electrons for many accelerator applications. These sources are in principle scalable to high currents witho…
Observation Of Repetition-Rate Dependent Emission From an Un-Gated Thermionic Cathode RF Gun
J. P. Edelen, Y. Sun, J. R. Harris +1
Recent work at Fermilab in collaboration with the Advanced Photon Source and members of other national labs, designed an experiment to study the relationship between the RF repetit…
First Steps Toward Incorporating Image Based Diagnostics Into Particle Accelerator Control Systems Using Convolutional Neural Networks
A. L. Edelen, S. G. Biedron, S. V. Milton +1
At present, a variety of image-based diagnostics are used in particle accelerator systems. Often times, these are viewed by a human operator who then makes appropriate adjustments…
