Fast ignition is a new method for inertial confinement fusion (ICF) in which the compression and ignition steps are separated. In the first stage, fuel is compressed by laser or ion beams. In the second phase, relativistic electrons are generated by pettawat laser in the fuel. Also, in the second phase 5-35 MeV protons can be generated in the fuel. Electrons or protons can penetrate in to the u...

In this study, to calculate the radioactivity of radioisotopes such as 11C, 15O, 18F and 123,124I in a focus plasma device for the production of medical radioisotopes, the particles of neutrons and protons with cubic targets of Nitrogen, Xenon, Carbon and a solid natural Boron is used. Particles energy are at the input of the program from 1MeV to 10MeV. Also, the total yield coefficient is cons...

Introduction: Depth-dose distribution curve of protons in the matter has a maximum is called Bragg peak. Bragg peak of a monoenergetic proton beam is too narrow. The spread out Bragg peak should be created for full coverage of the tumor. The spread out Bragg peak is obtained in the depth of the tumor with superposition of the several Bragg peaks. The aim of this study was coverage of an eye tum...

Nowadays, due to the high costs and large dimensions of the conventional proton accelerators, other optimal methods for producing the proton beam have been studied. Using of Laser-driven proton accelerators is one of the important and new methods. In laser-driven ion acceleration, a highly ultra-intense laser pulse interacts with solid density targets and will create a plasma media that will ac...
