Muography, traditionally recognized as a potent instrument to visualize the internal structure of gigantic objects, has spawned some novel interdisciplinary applications such as an underground navigator. To better serve interdisciplinary purposes and cope with various challenging environments, we develop a scintillation detector called MuGrid for the sake of stability and low cost. By coupling...

In the Fermilab Muon g-2 experiment, the anomalous precession frequency of the muon was extracted from calorimeter data that recorded the energy and time spectrum of the positrons. The probability of a calorimeter detecting a positron from muon decay exhibits spatial and energy dependence, as well as variations due to the materials in the vicinity of the calorimeter. Coupled with muon beam...

The investigation of a permanent electric dipole moment (EDM) in elementary particles offers a compelling avenue to explore Charge-Parity symmetry violation, a phenomenon intimately connected with the observed matter-antimatter asymmetry in the universe. The Standard Model (SM) of particle physics predicts an exceedingly small muon EDM, on the order of $10^{-38}~e\cdot cm$. However, several...

The effectiveness of a spark chamber in detecting charged particles is contingent upon the timely recombination of ions after a Townsend avalanche, typically occurring over several microseconds. To achieve optimal spark efficiency, the system necessitates fast electronics capable of operating within a delay time of less than 500 ns.

Permanent electric dipole moments (EDMs) of elementary particles violate CP symmetry. Compared with the current muon EDM limit($|d_\mu| < 1.8 \times 10^{-19}e\cdot cm$) obtained from the BNL Muon g-2 Collaboration, the contribution to the muon EDM from the standard model is negligible ($|d_\mu| \sim 1.4 \times 10^{-38}e\cdot cm$), making the EDMs of elementary particles very sensitive probes...

Muon scattering tomography (MST) is a non-destructive technique to image various materials by utilizing cosmic ray muons as probes. A typical MST system with a two-fold track detectors is particularly effective in detecting high-$Z$ materials (e.g. nuclear materials), but difficult to recognize low-$Z$ materials (e.g. explosive materials). In this poster, we present a concept of MST system to...
