Abstract The nEXO neutrinoless double beta (0 νββ ) decay experiment is designed to use a time projection chamber and 5000 kg of isotopically enriched liquid xenon search for the in 136 Xe. Progress detector design, paired with higher fidelity its simulation an advanced data analysis, based on one used final results EXO-200, produce sensitivity prediction that exceeds half-life 10 28 years. Specifically, improvements have been made understanding production scintillation photons charge as...
Liquid xenon time projection chambers are promising detectors to search for neutrinoless double beta decay (0$\nu \beta \beta$), due their response uniformity, monolithic sensitive volume, scalability large target masses, and suitability extremely low background operations. The nEXO collaboration has designed a tonne-scale chamber that aims 0$\nu \beta$ of \ce{^{136}Xe} with projected half-life sensitivity $1.35\times 10^{28}$~yr. To reach this sensitivity, the design goal is $\leq$1\%...
Adaptive neurofuzzy inference system (ANFIS) is investigated to optimize the configuration of anode shape in plasma focus devices achieve highest X-ray yield. Variables discharge voltage, filling gas pressure, and angles slopes (Φ 1 Φ 2 ) are chosen as input parameters, while output designated be radiated hard intensity. The trained ANFIS has achieved good agreement with experimental results mean relative error percentages (MRE%) 1.12% 2.18% for training testing data, respectively. study...
Abstract Silicon photomultipliers (SiPMs) are emerging as the photodetector technology to be used in upcoming noble liquid experiments. Newly developed SiPMs sensitive vacuum ultraviolet (VUV) light will directly for readout of scintillation photons ( λ = 175 nm) from xenon future tonne-scale experiments, such nEXO, searching neutrinoless double beta decay 136 Xe. In this research project, VUV-SiPMs two different vendors characterized using current–voltage (IV) and pulse-level measurements...
Traditional methods struggle to find faults in power transmission lines. This paper presents an approach for short lines, leveraging the of wavelet transforms. analyze time-domain signals, limiting their ability differentiate fault transients. Wavelet transforms, offering a combined time-frequency analysis, provide deeper understanding these A detailed line model is built SIMULINK. Diverse scenarios are meticulously simulated, and current signals undergo transform analysis. Key features...
Incident particles and photons on semiconductor material with energies greater than 2 order of magnitude from the fundamental bandgap tend to produce more one electron-hole pair referred as quantum yield.
