zk-X509: Privacy-Preserving On-Chain Identity from Legacy PKI via Zero-Knowledge Proofs
Yeongju Bak
Public blockchains impose an inherent tension between regulatory compliance and user privacy. Existing on-chain identity solutions require centralized KYC attestors, specialized ha…
Quasi-monoenergetic Deuteron Acceleration via Boosted Coulomb Explosion by Reflected Picosecond Laser Pulse
Tianyun Wei, Zechen Lan, Yasunobu Arikawa +11
Generation of quasi-monoenergetic ions by intense laser is one of long-standing goals in laser-plasma physics. However, existing laser-driven ion acceleration schemes often produce…
Commit-Reveal: Securing Randomness Beacons with Randomized Reveal Order in Smart Contracts
Suhyeon Lee, Euisin Gee, Najmeh Soroush +2
Simple commit-reveal beacons are vulnerable to last-revealer strategies, and existing descriptions often leave accountability and recovery mechanisms unspecified for practical depl…
Fast physics-based launcher optimization for electron cyclotron current drive
N A Lopez, A Alieva, S A M McNamara +1
With the increased urgency to design fusion pilot plants, fast optimization of electron cyclotron current drive (ECCD) launchers is paramount. Traditionally, this is done by coarse…
Observation of quantum effects on radiation reaction in strong fields
Eva E. Los, Elias Gerstmayr, Christopher Arran +28
Radiation reaction, the force experienced by an accelerated charge due to radiation emission, has long been the subject of extensive theoretical and experimental research. Experime…
Inferring the scrape-off layer heat flux width in a divertor with a low degree of axisymmetry
C. Marsden, X. Zhang, M. Moscheni +7
Plasma facing components (PFCs) in the next generation of tokamak devices will operate in challenging environments, with heat loads predicted to exceed 10 MWm. The magnitude…
Realizing Laser-driven Deuteron Acceleration with Low Energy Spread via In-situ DO-deposited Target
Tianyun Wei, Yasunobu Arikawa, Seyed Reza Mirfayzi +10
Generation of quasi-monoenergetic ion pulse by laser-driven acceleration is one of the hot topics in laser plasma physics. In this study, we present a new method for the \textit{In…
Experimental observations of bifurcated power decay lengths in the near Scrape-Off Layer of tokamak plasmas
X Zhang, C Marsden, M Moscheni +14
The scrape-off layer parallel heat flux decay lengths measured at ST40, a high field, low aspect ratio spherical tokamak, have been observed to bifurcate into two groups. The wide…
Detection and characterisation of conductive objects using electromagnetic induction and a fluxgate magnetometer
Lucy Elson, Adil Meraki, Lucas M. Rushton +2
Eddy currents induced in electrically conductive objects can be used to locate metallic objects as well as to assess the properties of materials non-destructively without physical…
Unshielded portable optically pumped magnetometer for the remote detection of conductive objects using eddy current measurements
L. M. Rushton, T. Pyragius, A. Meraki +2
Electrically conductive objects can be detected using the principle of electromagnetic induction where a primary oscillating magnetic field induces eddy currents in the object, whi…
Tungsten boride shields in a spherical tokamak
Colin G Windsor, Jack O Astbury, James Davidson +4
The favourable properties of tungsten borides for shielding the central High Temperature Superconductor (HTS) core of a spherical tokamak fusion power plant are modelled using the…
Shape optimization of a weighted two-phase Dirichlet eigenvalue
Idriss Mazari, Grégoire Nadin, Yannick Privat
Let be a bounded function and a nonnegative parameter. This article is concerned with the first eigenvalue of the drifted Laplacian type operator …
The Experimental Program for High Pressure Gas Filled Radio Frequency Cavities for Muon Cooling Channels
Ben Freemire, Moses Chung, Pierrick M. Hanlet +4
An intense beam of muons is needed to provide a luminosity on the order of 10 cms for a multi-TeV collider. Because muons produced by colliding a multi-MW prot…
Palindromic discontinuous Galerkin method for kinetic equations with stiff relaxation
David Coulette, Emmanuel Franck, Philippe Helluy +2
We present a high order scheme for approximating kinetic equations with stiff relaxation. The objective is to provide efficient methods for solving the underlying system of conserv…
Kinetic simulations of X-B and O-X-B mode conversion and its deterioration at high input power
A. V. Arefiev, I. Y. Dodin, A. Köhn +4
Spherical tokamak plasmas are typically overdense and thus inaccessible to externally-injected microwaves in the electron cyclotron range. The electrostatic electron Bernstein wave…
