Generation of 10-m-lengthscale plasma columns by resonant and off-resonant laser pulses

G. Demeter, J. T. Moody, M. A. Kedves +7

Creating extended, highly homogeneous plasma columns like that required by plasma wakefield accelerators can be a challenge. We study the propagation of ultra-short, TW power ioniz…

The AWAKE Run 2 programme and beyond

Edda Gschwendtner, Konstantin Lotov, Patric Muggli +99

Plasma wakefield acceleration is a promising technology to reduce the size of particle accelerators. Use of high energy protons to drive wakefields in plasma has been demonstrated…

Controlled Growth of the Self-Modulation of a Relativistic Proton Bunch in Plasma

L. Verra

A long, narrow, relativistic charged particle bunch propagating in plasma is subject to the self-modulation (SM) instability. We show that SM of a proton bunch can be seeded by the…

Analysis of Proton Bunch Parameters in the AWAKE Experiment

V. Hafych, A. Caldwell, R. Agnello +85

A precise characterization of the incoming proton bunch parameters is required to accurately simulate the self-modulation process in the Advanced Wakefield Experiment (AWAKE). This…

Simulation and Experimental Study of Proton Bunch Self-Modulation in Plasma with Linear Density Gradients

P. I. Morales Guzmán, P. Muggli, R. Agnello +88

We present numerical simulations and experimental results of the self-modulation of a long proton bunch in a plasma with linear density gradients along the beam path. Simulation re…

Long range propagation of ultrafast, ionizing laser pulses in a resonant nonlinear medium

G. Demeter, J. T. Moody, M. Aladi +18

We study the propagation of 0.05-1 TW power, ultrafast laser pulses in a 10 meter long rubidium vapor cell. The central wavelength of the laser is resonant with the line of r…

Transition between Instability and Seeded Self-Modulation of a Relativistic Particle Bunch in Plasma

F. Batsch, P. Muggli, R. Agnello +94

We use a relativistic ionization front to provide various initial transverse wakefield amplitudes for the self-modulation of a long proton bunch in plasma. We show experimentally t…

Experimental study of extended timescale dynamics of a plasma wakefield driven by a self-modulated proton bunch

J. Chappell, E. Adli, R. Agnello +96

Plasma wakefield dynamics over timescales up to 800 ps, approximately 100 plasma periods, are studied experimentally at the Advanced Wakefield Experiment (AWAKE). The development o…

Proton beam defocusing in AWAKE: comparison of simulations and measurements

A. A. Gorn, M. Turner, E. Adli +96

In 2017, AWAKE demonstrated the seeded self-modulation (SSM) of a 400 GeV proton beam from the Super Proton Synchrotron (SPS) at CERN. The angular distribution of the protons defle…

Proton Bunch Self-Modulation in Plasma with Density Gradient

F. Braunmüller, T. Nechaeva, AWAKE Collboration

We study experimentally the effect of linear plasma density gradients on the self-modulation of a 400\,GeV proton bunch. Results show that a positive/negative gradient in/decreases…

Experimental Study of Wakefields Driven by a Self-Modulating Proton Bunch in Plasma

M. Turner, P. Muggli, the AWAKE Collaboration

We study experimentally the longitudinal and transverse wakefields driven by a highly relativistic proton bunch during self-modulation in plasma. We show that the wakefields' growt…

Proton Driven Plasma Wakefield Acceleration in AWAKE

Edda Gschwendtner, Marlene Turner, the AWAKE Collaboration

In this article, we briefly summarize the experiments performed during the first Run of the Advanced Wakefield Experiment, AWAKE, at CERN (European Organization for Nuclear Researc…

Observation of Two-photon Photoemission from Cesium Telluride Photocathodes Excited by a Near-infrared Laser

H. Panuganti, P. Piot

We explore nonlinear photoemission in cesium telluride (CsTe) photocathodes where an ultrashort ( fs full width at half max) 800-nm infrared laser is used as the driv…

Ampère-Class Pulsed Field Emission from Carbon-Nanotube Cathodes in a Radiofrequency Resonator

D. Mihalcea, L. Faillace, J. Hartzell +5

Pulsed field emission from cold carbon-nanotube cathodes placed in a radiofrequency resonant cavity was observed. The cathodes were located on the backplate of a conventional $1+\f…
