The DarkLight Experiment: A Precision Search for New Physics at Low Energies
J. Balewski, J. Bernauer, J. Bessuille +37
We describe the current status of the DarkLight experiment at Jefferson Laboratory. DarkLight is motivated by the possibility that a dark photon in the mass range 10 to 100 MeV/c$^…
Multi-component measurements of the Jefferson Lab energy recovery linac electron beam using optical transition and diffraction radiation
M. A. Holloway, R. B. Fiorito, A. G. Shkvarunets +5
High brightness electron accelerators, such as energy recovery linacs (ERL), often have complex particle distributions that can create difficulties in beam transport as well as mat…
Science Requirements and Conceptual Design for a Polarized Medium Energy Electron-Ion Collider at Jefferson Lab
S. Abeyratne, A. Accardi, S. Ahmed +55
This report presents a brief summary of the science opportunities and program of a polarized medium energy electron-ion collider at Jefferson Lab and a comprehensive description of…
Transmission of High-Power Electron Beams Through Small Apertures
C. Tschalaer, R. Alarcon, S. Balascuta +19
Tests were performed to pass a 100 MeV, 430 kWatt c.w. electron beam from the energy-recovery linac at the Jefferson Laboratory's FEL facility through a set of small apertures in a…
Measured Radiation and Background Levels During Transmission of Megawatt Electron Beams Through Millimeter Apertures
R. Alarcon, S. Balascuta, S. V. Benson +20
We report measurements of photon and neutron radiation levels observed while transmitting a 0.43 MW electron beam through millimeter-sized apertures and during beam-off, but accele…
Transmission of Megawatt Relativistic Electron Beams Through Millimeter Apertures
R. Alarcon, S. Balascuta, S. V. Benson +18
High power, relativistic electron beams from energy recovery linacs have great potential to realize new experimental paradigms for pioneering innovation in fundamental and applied…
DarkLight: A Search for Dark Forces at the Jefferson Laboratory Free-Electron Laser Facility
J. Balewski, J. Bernauer, W. Bertozzi +64
We give a short overview of the DarkLight detector concept which is designed to search for a heavy photon A' with a mass in the range 10 MeV/c^2 < m(A') < 90 MeV/c^2 and which deca…
The application of encoder-decoder neural networks in high accuracy and efficiency slit-scan emittance measurements
S. Ma, A. Arnold, P. Michel +9
A superconducting radio-frequency (SRF) photo injector is in operation at the electron linac for beams with high brilliance and low emittance (ELBE) radiation center and generates…
European Strategy for Particle Physics -- Accelerator R&D Roadmap
C. Adolphsen, D. Angal-Kalinin, T. Arndt +133
The 2020 update of the European Strategy for Particle Physics emphasised the importance of an intensified and well-coordinated programme of accelerator R&D, supporting the design a…
