the response of tissue equivalent Proportional Counters to heavy ions
Radiation Research, 2002Co-Authors: Hooshang Nikjoo, Igor K Khvostunov, Francis A CucinottaAbstract:Abstract Nikjoo, H., Khvostunov, I. K. and Cucinotta, F. A. The Response of Tissue-Equivalent Proportional Counters to Heavy Ions. Radiat. Res. 157, 435–445 (2002). The paper presents a theoretical model for the response of a tissue-equivalent Proportional counter (TEPC) irradiated with charged particles. Heavy ions and iron ions in particular constitute a significant part of radiation in space. TEPCs are used for all space shuttle and International Space Station (ISS) missions to estimate the dose and radiation quality (in terms of lineal energy) inside spacecraft. The response of the tissue-equivalent Proportional Counters shows distortions at the wall/cavity interface. In this paper, we present microdosimetric investigation using Monte Carlo track structure calculations to simulate the response of a TEPC to charged particles of various LET (1 MeV protons, 2.4 MeV α particles, 46 MeV/nucleon 20Ne, 55 MeV/nucleon 20Ne, 45 MeV/nucleon 40Ar, and 1.05 GeV/nucleon 56Fe). Data are presented for energy lost an...

full simulation of the sudbury neutrino observatory Proportional Counters
New Journal of Physics, 2011Co-Authors: B Beltran, H Bichsel, B Cai, G A Cox, H Deng, J A Detwiler, J A Formaggio, S HabibAbstract:The third phase of the Sudbury Neutrino Observatory (SNO) experiment added an array of 3He Proportional Counters to the detector. The purpose of this neutral-current detection (NCD) array was to observe neutrons resulting from neutral-current solar-neutrino–deuteron interactions. We have developed a detailed simulation of current pulses from NCD array Proportional Counters, from the primary neutron capture on 3He through NCD array signal-processing electronics. This NCD array MC simulation was used to model the alpha-decay background in SNO's third-phase 8B solar-neutrino measurement.

an array of low background 3he Proportional Counters for the sudbury neutrino observatory
Nuclear Instruments & Methods in Physics Research Section A-accelerators Spectrometers Detectors and Associated Equipment, 2007Co-Authors: J F Amsbaugh, M.c. Browne, T.j. Bowles, Juan Manuel Anaya, J Banar, T V Bullard, T H Burritt, G A Coxmobrand, X Dai, H DengAbstract:An array of Neutral-Current Detectors (NCDs) has been built in order to make a unique measurement of the total active flux of solar neutrinos in the Sudbury Neutrino Observatory (SNO). Data in the third phase of the SNO experiment were collected between November 2004 and 2006, after the NCD array was added to improve the neutral-current sensitivity of the SNO detector. This array consisted of 36 strings of Proportional Counters filled with a mixture of 3He and CF4 gas capable of detecting the neutrons liberated by the neutrino-deuteron neutral-current reaction in the D2O, and four strings filled with a mixture of 4He and CF4 gas for background measurements. The Proportional counter diameter is 5 cm. The total deployed array length was 398 m. The SNO NCD array is the lowest-radioactivity large array of Proportional Counters ever produced. This article describes the design, construction, deployment, and characterization of the NCD array, discusses the electronics and data acquisition system, and considers event signatures and backgrounds.
