Experimental discrimination of ion stopping models near the Bragg peak in highly ionized matter
The energy deposition of ions in dense plasmas is a key process in inertial confinement fusion that determines the α-particle heating expected to trigger a burn wave in the hydrogen pellet and resulting in high thermonuclear gain. However, measurements of ion stopping in plasmas are scarce and mostly restricted to high ion velocities where theory agrees with the data. Here, we report experiment...
متن کاملMeasurements of Ion Stopping Around the Bragg Peak in High-Energy-Density Plasmas.
For the first time, quantitative measurements of ion stopping at energies around the Bragg peak (or peak ion stopping, which occurs at an ion velocity comparable to the average thermal electron velocity), and its dependence on electron temperature (T(e)) and electron number density (n(e)) in the range of 0.5-4.0 keV and 3×10(22) to 3×10(23) cm(-3) have been conducted, respectively. It is experi...
متن کاملThe Influense of Target Matter Porosity on Ion Stopping Characteristics
To get an accurate description of has-dynamic motions at the target irradiation with an ion beam we must know the profile of energy release during ion stopping. The experimental dependence dE/dx in graphite with different densities, obtained during the experiments at the SIS-18 (GSI) accelerator by the team of VNIIEF, ITEP and GSI specialists, is presented in Fig.1 [1]. The experimental depende...
متن کاملBaryon stopping as a probe for highly excited nuclear matter
The amount of baryon stopping in central P b + P b collisions from 20 – 160 A·GeV as well as hyperon rapidity distributions are calculated within the UrQMD model in comparison to experimental data at 40, 80 and 160 A·GeV taken recently from the NA49 collaboration. Furthermore, the amount of baryon stopping at 160 A·GeV for P b+P b collisions is studied as a function of centrality in comparison ...
متن کاملA new model for Spread Out Bragg Peak in proton therapy of uveal melanoma
In this research, in order to improve our calculations in treatment planning for proton radiotherapy of ocular melanoma, we improved our human eye phantom planning system in GEANT4 toolkit. Different analytical models have investigated the creating of Spread Out Bragg Peak (SOBP) in the tumor area. Bortfeld’s model is one of the most important analytical methods. Using convolution method, a new...
