The upcoming High-Luminosity phase of the Large Hadron Collider (HL-LHC) will deliver unprecedented luminosities, posing significant challenges for particle reconstruction and pile-up mitigation. To preserve excellent tracking and vertexing performance under these conditions, the ATLAS experiment is developing the High Granularity Timing Detector (HGTD), a precision timing layer capable of...

The X-ArT (Xenon-Argon Technology) collaboration has studied the scintillation mechanisms in pure and Xe-doped liquid argon (LAr) using silicon photomultipliers sensitive to different wavelength ranges. Thanks to our measurements we identified a long-lived (>10μs) component attributed to extreme ultraviolet (EUV) photons emitted by the metastable levels of atomic argon. Based on this...

I am starting my second year thesis at Paris-Saclay university / CEA, within the ERC G-LEAD project, on the development of innovative electronics for a radiometer aimed at QCD axion dark matter searches.
Go to contribution page
My thesis focuses on developing a radiometer covering a frequency band from 10 GHz to 40 GHz, corresponding to a axion mass range of $50\mu$eV to $150\mu$eV.
This detector is designed to... -

Dans le cadre des projets de collisionneurs leptoniques futurs, un prototype de calorimètre hadronique ultra granulaire, le SDHCAL, a été réalisé à l’IP2I.

Pour les projets de collisionneurs leptoniques circulaires comme le FCC et le CEPC, il est proposé d’adjoindre au SDHCAL une capacité de mesures précises du temps pour former un calorimètre ultra granulaire en temps et espace. Cette... -

The new 3γ imaging technique, based on the use of the radionuclide 44Sc, enables the direct three-dimensional reconstruction of a radioactive source from the simultaneous detection of three gamma photons. This approach has the potential to reduce both acquisition time and injected activity compared to conventional nuclear imaging methods. To investigate this concept, a liquid xenon Compton...

Abstract: The C70XP cyclotron at ARRONAX, located in Saint Herblain [1], is capable of delivering different types of particle beams: Protons and alpha particles up to 70 MeV & deuterons up to 35 MeV. At the cyclotron level, in standard mode, bunches of ions can be delivered with a duration of 3ns separated by 33ns each, and beam intensities ranging from very low (< 1 pA) to very high (up to...

The High-Luminosity upgrade of the Large Hadron Collider (HL-LHC) is scheduled to begin colliding protons in 2028. This increase of luminosity will induce a larger number of collisions per beam crossing (around 200). This phenomenon is called the pile-up (μ). A High Granularity Timing Detector (HGTD) has been proposed for the ATLAS experiment to address this new challenges. This new ATLAS...

With the High Luminosity LHC (HL-LHC) upgrade scheduled for 2030, a major upgrade of the LHCb experiment is planned to adapt to the expected harsh environment. At the Upstream (UP) and MightyTracker (MT) tracking stations, Monolithic Active Pixel Sensors (MAPS) have been chosen for their high resistivity to radiation and their small pixel sizes. This high granularity and the higher pile-up at...

Coherent elastic neutrino nucleus scattering (CEvNS) was first measured experimentally by the COHERENT experiment in 2017 and is currently being studied by many experiments all around the world. In this context, the Ricochet international collaboration aims to detect the CEvNS process in order to search for new physics. The detectors used are germanium crystals operated at cryogenic...

In this presentation, I present the optical design of the stable power and signal recycling cavities for the gravitational-wave detector Advanced Virgo+. First, I explain the importance of the stable cavities upgrade for improving the detector’s control and noise performances. The optical design of the cavities is developed to fit within the limited infrastructure available at the Virgo site....

Timing measurements are critical for the detectors at the future HL-LHC, to resolve reconstruction ambiguity when the number of simultaneous interactions reaches up to 200 per bunch crossing. The ATLAS collaboration therefore builds a new High-Granularity Timing detector for the forward region. A customized ASIC, called ALTIROC, has been developed, to read out fast signals from low-gain...

The Large Hadron Collider (LHC) collides protons at nearly the speed of light, producing new particles observed by the ATLAS detector. In 2026, the LHC will undergo a major upgrade to the High-Luminosity LHC (HL-LHC), increasing luminosity by a factor of 5–7 and delivering up to 200 simultaneous collisions. To cope with the resulting data rates, ATLAS will replace the readout electronics of...
