Realization of a Faraday cup for the gun of PERLE

Sidi Mohammed Ben Abdillah, R. Roux, denis reynet, A. Bechtold

Faraday Cups have been used as diagnostic tools to measure the charged particle beam current directly. Up to now, different designs have been introduced for this purpose. In this work, a new design of Faraday Cup has been performed for the gun …

Commissioning of ThomX Compton source subsystems and demonstration of 10 10 x-rays/s

Muath Alkadi, M.A. Alves, Manar Amer, Loïc Amoudry et autres

ThomX is a compact x-ray source based on Compton scattering, installed at IJCLab (Laboratoire de physique des 2 infinis-Irène Joliot-Curie) in Orsay. The machine uses a small electron storage ring and an intense laser pulse stored in a high-finesse optical cavity. This …

Importance of radiolytic reactions during high-LET irradiation modalities: LET effect, role of O2 and radiosensitization by nanoparticles

Gérard Baldacchino, Émilie Brun, Ibtihel Denden, Sarah Bouhadoun et autres

This article reviews radiation chemistry processes induced by high-linear energy transfer (LET) radiation. The first part gives a short historical introduction and defines the essential concepts of radiation chemistry. It is aimed at radiobiologists in search of basics in this discipline, to …

Long time behavior in locally activated random walks

Nicolas Meunier, Clément Mouhot, R. Roux

We consider a 1-dimensional Brownian motion whose diffusion coefficient varies when it crosses the origin. We study the long time behavior and we establish different regimes, depending on the variations of the diffusion coefficient: emergence of a non-Gaussian mul-tipeaked probability distribution and …

Computation of sensitivities for the invariant measure of a parameter\n dependent diffusion

Roland Assaraf, Benjamin Jourdain, Tony Lelièvre, R. Roux

We consider the solution to a stochastic differential equation with a drift\nfunction which depends smoothly on some real parameter $\\lambda$, and admitting\na unique invariant measure for any value of $\\lambda$ around $\\lambda$ = 0. Our\naim is to compute the derivative with respect …
