In this work, the empirical parameterization describing the alpha particles’ track depth in CR-39 detectors is extended to describe longitudinal track profiles against etching time for protons and alpha particles. MATLAB based software is developed for this purpose. The software calculates and plots the depth, diameter, range, residual range, saturation time, and etch rate versus etching time. ...

Abstract IceCube is a cubic-kilometer Cherenkov telescope operating at the South Pole. The main goal of detection astrophysical neutrinos and identification their sources. High-energy muon are observed via secondary muons produced in charge current interactions with nuclei ice. Currently, best performing track directional reconstruction based on maximum likelihood method using arrival time dist...

X-ray polarimetry based on gas pixel detectors (GPDs) has reached a high level of maturity thanks to the Imaging Polarimeter Explorer (IXPE) providing first-ever spatially resolved polarimetric measurements. However, as this new technique, few unexpected effects have emerged in course in-flight operations. In particular, it was almost immediately found that, unpolarized calibration sources on-b...

Accurate feature detection is key to higher level decisions regarding image content. Within the domain of spectrogram track detection and classification, the detection problem is compounded by low signal to noise ratios and high track appearance variation. Evaluation of standard feature detection methods present in the literature is essential to determine their strengths and weaknesses in this ...

This paper describes preliminary work to develop a cosmic-radiation dosemeter for use by military aircraft crew. The dosemeter is based on a combination of CR-39 etched-track detectors and TLD-700 thermoluminescent detectors. It is intended that the CR-39 be used to assess the neutron dose, while the TLD700 is used to assess the photon and charged particle dose. The sensitivity of CR-39 to the ...

Two test detectors similar to the Pierre Auger Observatory Water Cherenkov Detectors have been installed at the Observatory site and at the Institut de Physique Nucléaire d’Orsay. The signals from the tanks are read out using three 9” photomultipliers and analyzed by both a digital oscilloscope with high sampling frequency and the Auger surface detector electronics. Additionally, the detectors ...
