Monte Carlo Studies on Proton Computed Tomography using a Silicon Strip Detector Telescope

Monte Carlo computer programs such as the GEANT4 toolkit include precise models of particle interactions and can be an invaluable tool for studying the feasibility of new imaging techniques such as proton computed tomography (pCT). Presented in this paper is a comparison of laboratory data with GEANT4 predictions for the imaging characteristics of a simple metal object using a particle beam and...

Role of 4π charged-particle detector arrays in lifetime measurements by Doppler-shift attenuation methods: The Microball

The effects introduced by 4π charged-particle detector arrays such as the Microball on lifetime measurements by Doppler-shift attenuation techniques are discussed. The effect originates from the lower efficiency for detecting charged particles at backward angles. Procedures for correcting for such “bias” are described.

R&d for Future Detectors

Detector R&D is advancing on many fronts of experimental particle physics, including efforts to produce massive, highly efficient, costeffective detectors for future neutrino experiments, for experiments requiring high bandwidth and high precision, such as hadron B factories, rare kaon decay experiments, and tau/charm factories, and for linear collider experiments. In recent years, the needs of...

The effect of source shield on landmine detection

Background: Several landmine detection methods, based on nuclear techniques, have been suggested during the recent years. Neutron energy moderation, neutron-induced gamma emission, neutron and gamma attenuation, and fast neutron backscattering are nuclear-based methods used for landmine detection. The aim of this study is to use backscattered neutron for landmine detection. Materials ...
