Calibration of the Large Area X-Ray Proportional Counter (LAXPC) Instrument on board AstroSat [PDF]

, 2017
We present the calibration and background model for the Large Area X-ray Proportional Counter (LAXPC) detectors on board AstroSat. The LAXPC instrument has three nominally identical detectors to achieve a large collecting area.

A multiball read-out for the spherical proportional counter [PDF]

, 2017
We present a novel concept of proportional gas amplification for the read-out of the spherical proportional counter. The standard single-ball read-out presents limitations for large diameter spherical detectors and high-pressure operations.

Analysis of micro-dose spectrum influencing factors based on tissue equivalent proportional counter

AIP Advances, 2021
The tissue equivalent proportional counter (TEPC) is often used in the measurement of ionizing radiation. However, there are many factors that can cause the micro-dose spectrum’s distortion and affect the accuracy of the measurement.

Liquid-Filled Proportional Counter [PDF]

Physical Review Letters, 1971
We report properties of single-wire proportional chambers and multiple-wire ionization chambers filled with liquid xenon. Proportional multiplication is seen for anode fields > 10{sup 6} volts/cm (anode-cathode voltage> 1 kV for a 3.5-{micro}-diam anode wire). The efficiency for detecting ionizing radiation is {approx} 100%.

Status and future prospects of the NEWS-G experiment

SciPost Physics Proceedings, 2023
The NEWS-G collaboration is searching for light dark matter using spherical proportional counters. Access to the mass range from 50 MeV to 10 GeV is enabled by the combination of low energy threshold, light gaseous targets (H, He, Ne), and highly radio ...

Toward neutron / gamma discrimination with proportional counter using artificial intelligence [PDF]

EPJ Web of Conferences
Extending the neutron detection capabilities of the ROSPEC SP2-1 proportional counter below 50 keV requires effective discrimination between neutron and gamma-ray signals at low energies.

Monte Carlo-based identification of electron and proton edges for calibration of miniaturized tissue equivalent proportional counter

Nuclear Engineering and Technology, 2023
Miniaturized tissue equivalent proportional counters (mini-TEPCs) are proper for radiation dosimetry in medical application because the small size of the dosimeter could prevent pile-up effect under the high intensity of therapeutic beam.
