چکیده

A drift collection calorimeter having a combined radiator and field shaping structure made of lead glass tubing is described. With the aid of the EGS Monte Carlo code we show that such a device, when pressurized to 10 atmospheres, will give a resolution of a/E = 9.6%/E1j2 provided that the shower is contained at a 99% level. Track length restriction and Landau sampling have been included in the EGS simulation. In addition, leading particle biasing and weighting techniques have been employed for the first time with EGS, with an increase in efficiency of about 100 to 300 for 10 GeV shower containment calculations.

Design and Simulation of Photoneutron Source by MCNPX Monte Carlo Code for Boron Neutron Capture Therapy

Introduction Electron linear accelerator (LINAC) can be used for neutron production in Boron Neutron Capture Therapy (BNCT). BNCT is an external radiotherapeutic method for the treatment of some cancers. In this study, Varian 2300 C/D LINAC was simulated as an electron accelerator-based photoneutron source to provide a suitable neutron flux for BNCT. Materials and Methods Photoneutron sources w...

A Comparative Study of the Construction of Positron Emission Tomography/Computed Tomography Facilities in Three South African Hospitals

Introduction: Development of higher energy modalities such as positron emission tomography/computed tomography (PET/CT), has led to more complex shielding problems. This is due to several factors, such as the radiopharmaceutical relatively high-administered activity, high patient throughput, and high energies of 511 kilo-electron volt (keV) positron annihilation photon...
