Single-Shot Ionization-Based Transverse Profile Monitor for Pulsed Electron Beams

Autor: Denham, Paul, Ody, Alex, Musumeci, Pietro, Burger, Nathan, Cook, Nathan, Andonian, Gerard

We present an experimental demonstration of a single-shot, non-destructive electron beam diagnostic based on the ionization of a low-density pulsed gas jet. In our study, 7~MeV electron bunches from a radio frequency (RF) photoinjector, carrying up t

A rotor-based multileaf collimator for beam shaping

Autor: Majernik, N., Andonian, G., Parrack, A., Rosenzweig, J. B., Doran, S., Wisniewski, E., Power, J.

We introduce a new style of multileaf collimator which employs rotors with angularly dependent radius to control the masking aperture: a rotor-based multileaf collimator (RMLC). Using a padlock-inspired mechanism, a single motor can set dozens of rot

Reconstructing Gamma-ray Energy Distributions from PEDRO Pair Spectrometer Data

Autor: Yadav, M., Oruganti, M. H., Naranjo, B., Andonian, G., Apsimon, Ö., Welsch, C. P., Rosenzweig, J. B.

Photons emitted from high-energy electron beam interactions with high-field systems, such as the upcoming FACET-II experiments at SLAC National Accelerator Laboratory, may provide deep insight into the electron beam's underlying dynamics at the inter

Analysis of the blowout plasma wakefields produced by drive beams with elliptical symmetry

Autor: Manwani, P., Kang, Y., Mann, J., Naranjo, B., Andonian, G., Rosenzweig, J. B.

In the underdense (blowout) regime of plasma wakefield acceleration (PWFA), the particle beam is denser than the plasma. Under these conditions, the plasma electrons are nearly completely rarefacted from the beam channel, resulting in a nominally uni
