Abstract A numerical model based on hydrodynamic approach has been developed to emulate the device dynamics of active target Time Projection Chamber which is utilized for studying nuclear reaction through three-dimensional tracking concerned low-energy particles. The proposed used investigate performance a prototype Chamber, namely SAT-TPC, be fabricated at Saha Institute Nuclear Physics, its application in physics experiments. case study non-relativistic elastic scattering 4 He + 12 C with...
Abstract Muography [1] utilizes cosmic muon interactions to image and analyze material properties. Electromagnetic cause trajectories deviate [2] (or even absorbed [1]), with the magnitude of deviation (absorption) reflecting material's characteristics. These modifications in muons can be utilized generate images a target object their path infer its composition geometry. Position-sensitive detectors, such as various gaseous ionization solid-state emulsion-based detectors are typically used...
The fragment angular distributions and excitation functions of the fission following complete fusion (FFCF) have been measured after separating them from targetlike-fragment (TLFF) for $^{19}\mathrm{F}$${+}^{232}$Th system in bombarding energy range 84.5 to 106.5 MeV. fraction was observed increase with decreasing below Coulomb barrier. function reaction agrees well coupled channel calculations. However, 〈${\mathit{l}}^{2}$〉 values derived anisotropy data FFCF events are found be much larger...
Gas Electron Multipliers (GEM) are a proven position sensitive gas detector technology which nowadays is becoming more widely used in High Energy Physics. GEMs offer an excellent spatial resolution and high particle rate capability, with close to 100% detection efficiency. In view of the luminosity phase CERN Large Hadron Collider, these aforementioned features make suitable candidates for future upgrades Compact Muon Solenoid (CMS) detector. particular, CMS GEM Collaboration proposes cover...
A Boundary Element Method (BEM) solver based on the solution of boundary integral equations potential and electric field has been developed to simulate 3D electrostatic configuration in gaseous detectors.

The nearly exact (neBEM) implemented order physical weighting configurations several detectors like MultiWire Proportional Counter Time Projection Chamber....
Fission fragment angular distributions have been measured for fission following full momentum transfer in ${}^{11}\mathrm{B}$, ${}^{12}\mathrm{C}$, ${}^{16}\mathrm{O}$, and ${}^{19}\mathrm{F}{+}^{232}\mathrm{Th}$ systems from above barrier to below sub-barrier energies. The anisotropies $[W({0}^{\ensuremath{\circ}})/W({90}^{\ensuremath{\circ}})]$ are found exhibit an anomalous peaklike structure the fusion all systems. This has a universal behavior independent of entrance channel mass...
Fission fragment mass distribution has been studied for the system $^{19}\mathrm{F}+^{232}\mathrm{Th}$ over an energy range of $105.4\phantom{\rule{0.3em}{0ex}}\text{MeV}$ to $84.2\phantom{\rule{0.3em}{0ex}}\text{MeV}$ in laboratory frame. For energies, above Coulomb barrier, variance distributions ${\ensuremath{\sigma}}_{m}^{2}$ varies linearly with temperature fused system, signifying statistical fusion-fission reaction. However, as decreases through a rapid increase is observed first time...
The India based Neutrino Observatory (INO) collaboration is planning to build a 50 kton magnetized iron calorimeter (ICAL) detector study neutrino oscillations and measure their associated parameters. ICAL will use 28,800 glass Resistive Plate Chambers (RPCs) of 2m × size be operated in the avalanche mode, as its active elements. As part R & D develop RPCs, we studied effect Sulfur hexaflouride (SF6) when it added small amount gas composition used for running RPCs. In this paper, present...
The operation of gas detectors is often limited by secondary effects, originating from avalanche-induced photons and ions. Ion backflow one the effects limiting a detector at high flux, giving rise to space charge which disturbs electric field locally. For Micromegas detector, large fraction positive ions created in avalanche can be stopped micro-mesh. present work involves measurements ion (using an experimental setup comprising two drift planes) bulk as function design parameters. These...
