163. Virgo and back-scattered light: Characterization of components of gravitational wave detector

Augustin DEMAGNY

Instrumentation

Black hole and neutron star are massive objects which, when in a binary system, generate gravitational wave. These waves can be used to measure the local expansion of the universe, measure the star population, for multi-messenger astronomy, and a lot of other fields.

The Virgo interferometer, at Pisa, is a second generation gravitational wave detector, which can detect these phenomenon. For...

98. Analysis of HGCAL timing performance in the 2025-2026 testbeam campaign at CERN

Instrumentation

The High-Luminosity phase of the Large Hadron Collider (HL-LHC), is expected to start in 2030. It will bring around a 2.5-to-4-fold increase in instantaneous luminosity, raising pileup up to 200 collisions per bunch crossing and increasing radiation damage to the detectors. To cope with this pileup and replace aging components, several subdetectors of the major experiments must be upgraded...

120. Performance Studies and Optimization of the Backward Electromagnetic Calorimeter for the ePIC Detector at the Electron–Ion Collider

Instrumentation

The Relativistic Heavy Ion Collider (RHIC) will be revamped as the Electron-Ion Collider (EIC), and the STAR detector will be replaced by the ePIC detector. We are developing backward electromagnetic calorimeters (ECal) to meet the energy-resolution requirements listed in the EIC Yellow Report. The energy resolution of the backward ECal prototype was measured during a beam test at the...

168. Electric field studies in LXe TPCs

Veronica CAZZOLA (LPNHE)

27/11/2026 14:25

Instrumentation

Liquid Xenon Time Projection Chambers (LXe-TPCs) represent a leading technology in the direct search for WIMP dark matter and rare event physics. Achieving high sensitivity requires precise control over the electric field, signal extraction, and light collection within the active volume. This talk presents recent advancements in electric field modeling for the XENONnT experiment,...

158. Low-level data analysis from NectarCAM tests

Amélie CLÉMENT (LP2IB)

Instrumentation

Gamma-ray Astrophysics focuses on the origin of Cosmic Rays in our Universe. These are high energy charged particles and nuclei which are accelerated and deviated by shocked media and high magnetic fields. Through violent and non-thermal processes, they lead to high-energy photon production, from Giga-electron-volts (GeV) and beyond. These gamma rays, when emitted in our direction, can be...

147. Modelling and Characterization of a Thz-Driven Accelerator Structure

Instrumentation

Terahertz (THz) acceleration is a promising approach toward compact electron accelerators, combining high accelerating fields with structures significantly smaller than conventional radiofrequency systems. Within the TWAC (Terahertz Wave Accelerating Cavity) Project , my PhD focuses on the modelling and characterization of the dielectric-lined accelerating waveguide “ZITA”.

The structure is...

164. Performance Characterization of the ProtoDUNE-VD Photon Detection System

Instrumentation

The Deep Underground Neutrino Experiment (DUNE) is a next-generation long-baseline neutrino experiment designed to address fundamental open questions in neutrino physics. DUNE will study neutrino oscillations using a beam produced at Fermilab, with a Near Detector to characterise the beam and a Far Detector comprising four modules located 1,300 km away in South Dakota. One of these modules...
