Invited Speaker / Conférencier(ère) invité(e)

Hyper-Kamiokande is the next-generation underground water Cherenkov detector being built in Japan and will study neutrinos originating from the J-PARC accelerator complex, the atmosphere and astrophysical sources. Its rich physics program includes the measurement of the leptonic CP-violation phase, neutrino astronomy, as well as the search for proton decay.

Hyper-Kamiokande consists of a...

Hyper-Kamiokande is a next-generation water Cherenkov detector currently under construction for the precision measurements of neutrino oscillations and the search for charge-parity symmetry violation. The far detector will contain 260,000 metric tons of ultra-pure water and will be the world’s largest underground neutrino experiment, instrumented with 20,000 20-inch photomultiplier tubes...

Bubble chamber technology has been a mainstay of the particle detection landscape since its invention in the 1950s. By employing a superheated liquid target, bubble chambers enable dual-channel particle identification through correlated visual and acoustic signals generated during bubble nucleation. The Scintillating Bubble Chamber (SBC) experiment is advancing this well-established detector...

The Scintillating Bubble Chamber (SBC) dark matter experiment uses superheated xenon-doped liquid argon to probe new areas of the WIMP mass-cross section parameter space. Accurate simulations of the behaviour of both the liquid argon active volume and CF4 hydraulic fluid components of the detector are integral to ensuring smooth operation and an accurate understanding of nucleation threshold....

699. New Modular Analysis Framework for the Multi-channel Read-out of the NEWS-G Dark Matter Experiment for Directional sensitivity

Oral Competition (Undergraduate Student) / Compétition orale (Étudiant(e) du 1er cycle)

New Experiments With Spheres-Gas (NEWS-G) direct dark matter search experiment is using spherical proportional counters filled with light noble gases, enabling sensitivity to very low-mass dark matter parameter space. It is equipped with a high-voltage 11-anode sensor “ACHINOS”, to detect electrons from ionizing radiation from only two combined channels currently. Independent readout of the 11...

736. Developing Scalable Readout Electronics for Directional Sensitivity of the NEWS-G Dark Matter Experiment

Particle Physics / Physique des particules (PPD)

Oral Competition (Undergraduate Student) / Compétition orale (Étudiant(e) du 1er cycle)

The New Experiments With Spheres-Gas (NEWS-G) uses a spherical proportional counter filled with a light noble gas mixture to directly detect light dark matter particles. The detector consists of a large sphere, equipped with a high-voltage 11-anode sensor, the “ACHINOS”, to detect electrons from ionizing radiation. The current electronics setup limits the readout to two channels, combining the...
