Application of FLUKA code to gamma-ray attenuation, energy deposition and dose calculations

Background: In radiation therapy, water is the phantom material of choice, both for reference and for relative dosimetry measurements. Solid phantoms, however, are more useful for routine measurements because they tend to be more robust and easier to set up than water phantoms. Materials and Methods: FLUKA input data cards have been arranged in sequential order. A simple cylindrical geometry wi...

Measurement and Simulation of Neutron/Gamma-Ray Cross-Correlation Functions from Spontaneous Fission

We present an application of a digital pulse shape discrimination (PSD) technique for the novel measurement of cross-correlation functions from a spontaneous fission source. The measurement method allows for the collection of fast coincidences within a time window of the order of a few tens of nanoseconds. The use of PSD allows for the accurate acquisition of the coincidences in all particle co...
