Precise measurements of the proton electromagnetic form factor ratio $R = \mu_p G_E^p/G_M^p$ using polarization transfer method at Jefferson Lab have revolutionized understanding nucleon structure by revealing strong decrease $R$ with momentum $Q^2$ for $Q^2 \gtrsim 1$ GeV$^2$, in disagreement previous extractions from cross section measurements. In particular, results exposed limits applicability one-photon-exchange approximation and highlighted role quark orbital angular structure. The...
The REST-for-Physics (Rare Event Searches Toolkit for Physics) framework is a ROOT-based solution providing the means to process and analyze experimental or Monte Carlo event data. Special care has been taken on traceability of code validation results produced within framework, together with connectivity between data stored registered through specific version metadata members. development was originally motivated cover needs at Rare experiments (experiments looking phenomena having extremely...
We have measured the cross section for quasielastic $1p$-shell proton knockout in ${}^{16}\mathrm{O}({e,e}^{\ensuremath{'}}p)$ reaction at $\ensuremath{\omega}\phantom{\rule{0ex}{0ex}}=\phantom{\rule{0ex}{0ex}}0.439\mathrm{GeV}$ and ${Q}^{2}\phantom{\rule{0ex}{0ex}}=\phantom{\rule{0ex}{0ex}}0.8(\mathrm{GeV}/c{)}^{2}$ missing momentum ${P}_{\mathrm{miss}}\ensuremath{\le}355\mathrm{MeV}/c$. extracted response functions ${R}_{L+TT}$, ${R}_{T}$, ${R}_{\mathrm{LT}}$, left-right asymmetry,...
The PandaX-III experiment plans to search for neutrinoless double beta decay (0$νββ$) of $^{136}$Xe in the China JinPing underground Laboratory (CJPL). will use a high pressure gaseous Time Projection Chamber (TPC) register both energy and electron track topology an event. This article is devoted software side experiment. As tool we REST, framework developed reconstruction simulation TPC-based detector systems. We study potential background reduction by introducing appropiate parameters...
The physics program in Hall A at Jefferson Lab commenced the summer of 1997 with a detailed investigation $^{16}\mathrm{O}(e,{e}^{\ensuremath{'}}p)$ reaction quasielastic, constant $(q,\ensuremath{\omega})$ kinematics ${Q}^{2}\ensuremath{\approx}0.8\phantom{\rule{0.3em}{0ex}}{(\mathrm{GeV}∕c)}^{2}$, $q\ensuremath{\approx}1\phantom{\rule{0.3em}{0ex}}\mathrm{GeV}∕c$, and $\ensuremath{\omega}\ensuremath{\approx}445\phantom{\rule{0.3em}{0ex}}\mathrm{MeV}$. Use self-calibrating, self-normalizing,...
We report the design, construction, and initial commissioning results of a large high pressure gaseous Time Projection Chamber (TPC) with Micromegas modules for charge readout. The detector vessel has an inner volume about 600 L active 270 L. At 10 bar operating pressure, contains 20 kg xenon gas can image charged particle tracks. Drift electrons are collected by readout plane, which accommodates tessellation seven modules. Each covers square cm cm. A new type Microbulk is chosen this...
Micromegas (MICRO-MEsh GAseous Structure) detectors have found common use in different applications since their development 1996 by the group of I. Giomataris and G. Charpak. In this review article, we present implementations sub-detectors physics experiments highlight current state for innovative detection concepts with Micromegas.
Large-size hybrid and pixelized GEM-Micromegas gaseous detectors (40x40 cm$^2$ active area) were developed installed in 2014 2015 for the COMPASS2 physics program which started at same time. That involved particular two full years of Drell-Yan studies using a high-intensity pion beam on thick polarized target. Although placed behind absorber, they exposed to an important flux low energy neutrons photons. The designed drastically reduce discharge rate, major issue non-resistive Micromegas...
New Micromegas (Micro-mesh gaseous detectors) are being developed in view of the future physics projects planned by COMPASS collaboration at CERN. Several major upgrades compared to present detectors studied: standing five times higher luminosity with hadron beams, detection beam particles (flux up a few hundred kHz/mm2, 10 larger than for pixelized read-out central part, light and integrated electronics, improved robustness. Studies were done moved beam, two first prototypes tested muon...
