The future of high energy physics is dependent on advancements in particle colliders, with lepton colliders being one of the more promising avenues. The FCC-ee is one of these options, providing higher luminosities at Higgs mass or top quark anti-top quark production threshold. However, one of the key challenges in FCC-ee detector design is reducing material budget causing adverse effects and...
We propose to build a straw tracker for FCC-ee experiments. The straw tracker offers the advantage of a low material, a crucial factor in minimizing overall inner detector material budget. With the capability to achieve a single-hit resolution of approximately 100 microns per layer, and the potential for up to 100 layers, the straw tracker will play a pivotal role in momentum measurement,...
We propose a high-precision, fast, robust and cost-effective muon detector concept for an FCC-ee experiment. This design combines precision drift tubes with fast plastic scintillator strips to enable both spatial and timing measurements. The drift tubes deliver two-dimensional position measurements perpendicular to the tubes with a resolution around 100~$\mu$m. Meanwhile, the scintillator...
Cluster counting (dN/dx) offers significant promise for enhanced particle identification (PID) resolution compared to traditional dE/dx methods by measuring the number of primary ionization acts per unit length. However, future detectors such as IDEA operating under high-speed digitization face unprecedented data transfer rate challenges. We are developing advanced ML algorithms that...
High-pressure gaseous TPCs provide increased target density while preserving fine charged-particle tracking. This combination can allow for low energy detection thresholds while maintaining event rates suitable for rare-event searches and neutrino experiments, from sub-MeV nuclear recoils to few-GeV neutrino interactions. In alignment with an RDC 6 priority—developing gas amplification...
High pressure gaseous argon time projection chambers (HPgTPCs) are crucial for many applications, including neutrino oscillation analyses, rare event searches such as coherent elastic neutrino-nucleus scattering (CEvNS), and low-energy nuclear recoil detection. Current R&D efforts are focused on testing gas electron multipliers (GEMs) in high-pressure environments, which is critical for...
High-pressure gaseous TPCs (HPgTPCs) offer the tracking capabilities of gaseous detectors combined with an increased target density, making them particularly suitable for high-precision neutrino interaction measurements. However, developing readout electronics for these detectors poses unique challenges distinct from collider-based systems. The low occupancy typical of neutrino detection...
We report on the performance of compact, high definition Time Projection Chambers (TPCs) with pixel chip readout as part of the BEAST II beam background measurement project at SuperKEKB. The TPCs detect fast neutrons by measuring the three dimensional (3D) ionization distribution of nuclear recoils in ${}^4$He:CO${}_2$ gas at atmospheric pressure. We use these detectors to characterize the...
The directions of low energy nuclear recoils open windows into previously unprobed areas of physics. Specifically, directional detection of coherent elastic neutrino nucleus scattering (CE𝜈NS) would probe for new, beyond-the-standard-model (BSM) gauge bosons involved in that interaction as well as provide a tool for distinguishing between dark matter and neutrino scattering. This talk presents...
The Flexible, Ideal MPGD system (FIMS) is a collaborative effort to realize a detector whose performance is not limited by technology, but by the fundamental physics of particles interacting with matter. Designed to have applications spanning the extremes of gaseous TPC use-cases, the objective is to achieve ideal performance based on the metrics of: 3D spatial resolution, detection...
Over the past few decades, Micro Pattern Gaseous Detector (MPGD) technologies have been increasingly adopted as tracking detector options in High Energy and Nuclear Physics experiments thanks to their good spatial resolution, high-rate capability, stability and more importantly their ability for large area coverage at a relatively low cost compared to the alternative. The thin gap GEM-μRWELL...
The versatility of MPGD technology has drawn tremendous interest in both Nuclear and High Energy Physics communities to use as particle detector in experiments. Particle tracking detectors are integral part of Nuclear Physics experiment and MPGDs has established themselves as reliable tracking detectors due to their moderate material budget, low cost, moderate spatial resolution and relatively...
The upcoming MOLLER experiment at Jefferson Lab (JLab) will measure the parity-violating asymmetry by scattering longitudinally polarized electrons off unpolarized electrons with high precision in a liquid Hydrogen target. The high precision will enable a search for new physics beyond the standard model.
Twenty-eight large area triple Gas Electron Multiplier (GEM) detector-packages will be...
Large-area Micro-Pattern Gas Detectors (MPGDs) have become key components in the tracking systems of many major ongoing and future electron scattering experiments at Jefferson Lab (JLab). Various large-area Gas Electron Multiplier (GEM) trackers have been recently developed and constructed for three highly ranked experimental programs at JLab: the Super Bigbite Spectrometer (SBS), PRad-II, and...
