This study presents the results of Monte Carlo simulations to obtain stopping power of protons in energy ranges and materials of therapeutic importance. The source was modeled as a point source emitting mono-energetic pencil beam of protons. A cylinder containing the material of interest was placed in vacuum to represent the phantom, a cylinder of 30 cm radius and 100 cm height. A disk-shaped thin detector (r=2 cm) was created in this phantom to compute average values of absorbed dose and flux. Its thickness varied from simulation to simulation depending on the energy of the incoming source protons. Average flux and absorbed dose were computed in the detector cell to evaluate the value of the stopping power for the material of interest at that specific energy. The results obtained in this study are compared with the data from the NIST compilation. [ABSTRACT FROM AUTHOR]

In this work, we present a general overview about the implementation at ININ of a Particle Induced Gamma Emission (PIGE) analysis technique, based on the bombardment of samples by protons and deuterons at different energies within our tandem accelerator facility. As it is well known, this technique is based on the detection of γrays emitted by nuclei in a target following a charged particle irradiation. The main feature of this technique, apart from being non-destructive and low time consuming, is that it allows a multi-elemental analysis of a sample, permitting an isotopic identification of many nuclides. Advances and some preliminary results are presented. [ABSTRACT FROM AUTHOR]

Non-scaling Fixed Field Alternating Gradient accelerators (ns-FFAGs) show great potential for the acceleration of protons and light ions for the treatment of certain cancers. They have unique features as they combine techniques from the existing types of accelerators, cyclotrons and synchrotrons, and hence look to have advantages over both for this application. However, these unique features meant that it was necessary to build one of these accelerators to show that it works and to undertake a detailed conceptual design of a medical machine. Both of these have now been done. This paper will describe the concepts of this type of accelerator, show results from the proof-of-principle machine (EMMA) and described the medical machine (PAMELA). [ABSTRACT FROM AUTHOR]
