Further search for magnetic-field-induced neutron disappearance in an ultracold neutron beam

Gaby Brenot, B. Clément, Hanno Filter-Pieler, Daniel Galbinski et autres

We report the results of the second iteration of an experiment searching for neutron-hidden-neutron oscillations in a beam of ultracold neutrons, conducted at the PF2 facility of the Institut Laue Langevin (ILL). Oscillations were tested via neutron disappearance as a function of …

Euclid. I. Overview of the Euclid mission

Y. Mellier, J.A. Acevedo Barroso, A. Achúcarro, Jiřı́ Adámek et autres

The current standard model of cosmology successfully describes a variety of measurements, but the nature of its main ingredients, dark matter and dark energy, remains unknown. Euclid is a medium-class mission in the Cosmic Vision 2015-2025 programme of the European Space Agency …

PID Tuning using Cross-Entropy Deep Learning: a Lyapunov Stability Analysis

Hector Kohler, B. Clément, Thomas Chaffre

Underwater Unmanned Vehicles (UUVs) have to constantly compensate for the external disturbing forces acting on their body. Adaptive Control theory is commonly used there to grant the control law some flexibility in its response to process variation. Today, learning-based (LB) adaptive methods …

COLSim, a simulator for Hybrid Navigation Acceptability and Safety

B. Clément, Thomas Chaffre, Pouria Sarhadi, Marie Dubromel

Autonomous vessels have emerged as a prominent and accepted solution. However, achieving full autonomy for marine vessels requires the development of robust and reliable mission planning and control systems that can handle various encounters with manned and unmanned vessels while operating effectively …

Learning-based Integrated Cooperative Motion Planning and Control of Multi-AUVs

Behnaz Hadi, Alireza Khosravi, Pouria Sarhadi, B. Clément et autres

This paper introduces a learning-based solution tailored for the integrated motion planning and control of Multiple Autonomous Underwater Vehicles (AUVs). Tackling the complexities of cooperative motion planning, encompassing tasks such as waypoint tracking and self/obstacle collision avoidance, becomes challenging in a rule-based …

Search for Neutron-to-Hidden-Neutron Oscillations in an Ultracold Neutron Beam

G. Ban, J. Chen, T. Lefort, O. Naviliat-Cuncic et autres

Models that postulate the existence of hidden sectors address contemporary questions, such as the source of baryogenesis and the nature of dark matter. Neutron-to-hidden-neutron oscillations are among the possible mixing processes and have been tested with ultracold neutron storage and passing-through-wall experiments …

Search for an interaction mediated by axion-like particles with ultracold neutrons at the PSI

N. J. Ayres, G Bison, K. Bodek, V Bondar et autres

Abstract We report on a search for a new, short-range, spin-dependent interaction using a modified version of the experimental apparatus used to measure the permanent neutron electric dipole moment at the Paul Scherrer Institute. This interaction, which could be mediated by axion-like …

Determination of diffusion coefficients of mercury atoms in various gases from longitudinal spin relaxation in magnetic gradients

B. Clément, M. Guigue, A. Leredde, G. Pignol et autres

We present a method to measure the binary diffusion coefficient of mercury atoms in a gas at room temperature and low pressure. It is based on the measurement of the longitudinal spin relaxation of optically pumped mercury-199 atoms in a magnetic field …
