A new paradigm for the dynamics of the early Universe
Robin W. Tucker, Timothy J. Walton, Manuel Arrayás +1
This paper invokes a new mechanism for reducing a coupled system of fields (including Einstein's equations without a cosmological constant) to equations that possess solutions exhi…
Electromagnetism, Axions, and Topology: a first-order operator approach to constitutive responses provides greater freedom
Jonathan Gratus, Martin W. McCall, Paul Kinsler
We show how the standard constitutive assumptions for the macroscopic Maxwell equations can be relaxed. This is done by arguing that the Maxwellian excitation fields (D,H) should b…
Transverse phase space characterisation in the CLARA FE accelerator test facility at Daresbury Laboratory
A. Wolski, D. C. Christie, B. L. Militsyn +2
We compare three techniques for characterising the transverse phase space distribution of the beam in CLARA FE (the Compact Linear Accelerator for Research and Applications Front E…
Demonstration of a compact plasma accelerator powered by laser-accelerated electron beams
T. Kurz, T. Heinemann, M. F. Gilljohann +22
Plasma wakefield accelerators are capable of sustaining gigavolt-per-centimeter accelerating fields, surpassing the electric breakdown threshold in state-of-the-art accelerator mod…
Acceleration of relativistic beams using laser-generated terahertz pulses
Morgan T. Hibberd, Alisa L. Healy, Daniel S. Lake +12
Dielectric structures driven by laser-generated terahertz (THz) pulses may hold the key to overcoming the technological limitations of conventional particle accelerators and with r…
A Numerical Approach to Designing a Versatile Pepper-pot Mask for Emittance Measurement
Oznur Apsimon, Barney Williamson, Guoxing Xia
The pepper-pot method is a popular emittance measurement technique for high intensity beams at low energy such as those generated by photo-injectors. In this paper, the beam dynami…
Probing Ultrafast Magnetic-Field Generation by Current Filamentation Instability in Femtosecond Relativistic Laser-Matter Interactions
G. Raj, O. Kononenko, A. Doche +28
We present experimental measurements of the femtosecond time-scale generation of strong magnetic-field fluctuations during the interaction of ultrashort, moderately relativistic la…
Interplay between the Weibel instability and the Biermann battery in realistic laser-solid interactions
N. Shukla, K. Schoeffler, E. Boella +3
A novel setup allows the Weibel instability and its interplay with the Biermann battery to be probed in laser-driven collisionless plasmas. Ab initio particle-in-cell (PIC) simulat…
Particle-In-Cell simulations of the parallel proton firehose instability influenced by the electron temperature anisotropy in solar wind conditions
A. Micera, E. Boella, A. N. Zhukov +4
In situ observations of the solar wind show a limited level of particle temperature anisotropy with respect to the interplanetary magnetic field direction. Kinetic electromagnetic…
Measuring the Gain of a Micro-Channel Plate/Phosphor Assembly Using a Convolutional Neural Network
Michael Jones, Matthew Harvey, William Bertsche +2
This paper presents a technique to measure the gain of a single-plate micro-channel plate (MCP)/phosphor assembly by using a convolutional neural network to analyse images of the p…
An introduction to spatial dispersion: revisiting the basic concepts
Paul Kinsler
I describe three ways that the spatial properties of a wave propagation medium can cause dispersion, and propose that they should form the basics for correctly understanding and na…
Evaporating black-holes, wormholes, and vacuum polarisation: must they always conserve charge?
Jonathan Gratus, Paul Kinsler, Martin W. McCall
A careful examination of the fundamentals of electromagnetic theory shows that due to the underlying mathematical assumptions required for Stokes' Theorem, global charge conservati…
Maxwell's (D, H ) excitation fields: lessons from permanent magnets
Jonathan Gratus, Paul Kinsler, Martin W. McCall
Macroscopic Maxwellian electrodynamics consists of four field quantities along with electric charges and electric currents. The fields occur in pairs, the primary ones being the el…
Spin- and angle-resolved photoemission studies of the electronic structure of Si(110)"16x2" surfaces
N. K. Lewis, Y. Lassailly, L. Martinelli +8
The electronic structure of Si(110)"16 x 2" double-domain, single-domain and 1 x 1 surfaces have been investigated using spin- and angle-resolved photoemission at sample temperatur…
Low-Density Hydrodynamic Optical-Field-Ionized Plasma Channels Generated With An Axicon Lens
R. J. Shalloo, C. Arran, A. Picksley +9
We demonstrate optical guiding of high-intensity laser pulses in long, low density hydrodynamic optical-field-ionized (HOFI) plasma channels. An axicon lens is used to generate HOF…
The Core Design of a Small Modular Pressurised Water Reactor for Commercial Marine Propulsion
Aiden Peakman, Hywel Owen, Tim Abram
If international agreements regarding the need to significantly reduce greenhouse gas emissions are to be met then there is a high probability that the shipping industry will have…
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…
