“…Subsequently, the beryllium is divided into the two alpha particles of 2.74 MeV each. [1][2][3][4] The principle of the proton boron fusion therapy (PBFT) is based on this reaction as the radiation therapy technique. In the case of boron neutron capture therapy (BNCT), after the thermal neutron was captured by the labeled boron in the tumor region, an alpha particle is emitted from the capture reaction point.…”

Three alpha particles are emitted from the point of reaction between a proton and boron. The alpha particles are effective in inducing the death of a tumor cell. After boron is accumulated in the tumor region, the emitted from outside the body proton can react with the boron in the tumor region. An increase of the proton's maximum dose level is caused by the boron and only the tumor cell is damaged more critically. In addition, a prompt gamma ray is emitted from the proton boron reaction point. Here, we show that the effectiveness of the proton boron fusion therapy was verified using Monte Carlo simulations. We found that a dramatic increase by more than half of the proton's maximum dose level was induced by the boron in the tumor region. This increase occurred only when the proton's maximum dose point was located within the boron uptake region. In addition, the 719 keV prompt gamma ray peak produced by the proton boron fusion reaction was positively detected. This therapy method features the advantages such as the application of Bragg-peak to the therapy, the accurate targeting of tumor, improved therapy effects, and the monitoring of the therapy region during treatment.

On a fusion chain reaction via suprathermal ions in high-density H–¹¹B plasma

The 11B(p,3α) fusion reaction is particularly attractive for energy production purposes because of its aneutronic character and the absence of radioactive species among reactants and products. Its exploitation in the thermonuclear regime, however, appears to be prohibitive due to the low reactivity of the H–11B fuel at temperatures up to 100 keV. A fusion chain sustained by elastic collisions between the α particles and fuel ions, this way scattered to suprathermal energies, has been proposed as a possible route to overcome this limitation. Based on a simple model, this work investigates the reproduction process in an infinite, non-degenerate H–11B plasma, in a wide range of densities and temperatures which are of interest for laser-driven experiments ( 10 24 ≲ n e ≲ 10 28 cm − 3 , T e ≲ 100 keV , T i ∼ 1 keV ). In particular, cross section data for the α–p scattering which include the nuclear interaction have been used. The multiplication factor, k ∞ , increases markedly with electron temperature and less significantly with plasma density. However, even at the highest temperature and density considered, and despite a more than twofold increase by the inclusion of the nuclear scattering, k ∞ turns out to be of the order of 10−2 only. In general, values of k ∞ very close to 1 are needed in a confined scheme to enhance the suprathermal-to-thermonuclear energy yield by factors of up to 103 or 104.

“…To achieve a hot-ion mode in inertial confinement fusion using P-B-11, there have been proposals to generate a detonation wave [12][13][14][15]. Eliezer [13] showed that compressed fuel can be burned by an expanding ion fusion-burning wave preceded by an electron-conduction heat detonation wave.…”

In a Fermi-degenerate plasma, the rate of electron physical processes is much reduced from the classical prediction, possibly enabling new regimes for controlled nuclear fusion, including the hot-ion mode, a regime in which the ion temperature exceeds the electron temperature. Previous calculations of these processes in dense plasmas are now corrected for partial degeneracy and relativistic effects, leading to an expanded regime of self-sustained fusion.
