Design and characterization of next-generation tissue equivalent proportional counters for use in low energy neutron fields
Tissue Equivalent Proportional Counters (TEPCs) are devices that can measure the radiation dose levels for the mixed neutron and gamma ray fields that are encountered in nuclear facilities. TEPC designs typically consist of a low density gas sensitive volume surrounded by a solid wall, each of …

Investigation and use of dual (twin) low pressure proportional counters for active neutron-gamma mixed field dosimetry
… dose-rate measurements. Tissue equivalent proportional counters (TEPCs) have been used, but their accuracy is limited. In this study, a custom-built Cylindrical Graphite Proportional Counter (Cy-GPC) along with a twin Cylindrical TEPC (Cy-TEPC) has been extensively investigated for n-γ …

A measurement of the diffraction scattering of pions and protons from complex nuclei using multiwire proportional counters
… with the development and testing of mu1tiwire proportional counters. The second part involves the use of a proportional counter system in an experiment to study the diffraction scattering of protons and positive pions from various complex nuclei. A good precision experiment is made considerably …

Investigation of the ⁵¹V(n,d)⁵⁰Ti reaction
… The spectrometer consists of three multiwire proportional counters followed by a curved plastic scintillator. The proportional counters act as ΔE detectors and the scintillator acts as an energy detector. The ΔE - E method based on the Bethe - Bloch formula was used for particle …

An Analysis of the 3-He Proportional Counter Data from the Sudbury Neutrino Observatory Using Pulse Shape Discrimination
… analysis of the data from 3-He-filled proportional counters from the third phase of the Sudbury Neutrino Observatory (SNO) data. These counters were deployed in SNO's heavy water to independently detect neutrons produced by the neutral current interaction of 8-B solar neutrinos with …

Theoretical performance analysis of a novel hemispherical tissue equivalent proportional counter for neutron monitoring and dosimetry
… It has been demonstrated that Tissue Equivalent Proportional Counters (TEPCs) have the potential to improve the accuracy of neutron dosimetry in these reactor fields, and Multi-Element Tissue Equivalent Proportional Counters (METEPCs) could reduce the size of instrumentation required to do so. …

Calibration and background data analysis in the scope of the NEWS-G dark matter experiment
… of low mass dark matter, using spherical proportional counters filled with gas. The latest detector, a 140-cm diameter copper sphere, has collected data in the Fall of 2019 at the Laboratoire souterrain de Modane (LSM) as a preparation for its future operation at SNOLAB starting in 2021. A …

The effect of high dose rate on tissue equivalent proportional counter measurements in mixed neutron-gamma fields
Tissue equivalent proportional counters (TEPCs) are commonly used for radiation monitoring in areas where a mixture of neutron and photon radiations may be present, such as those commonly encountered in nuclear power plants. In such radiation fields, the dose rate of each component can vary …
