Nuclear reactions between protons and boron-11 nuclei (p–B fusion) that were used to yield energetic α-particles initiated in a plasma was generated by the interaction PW-class laser operating at relativistic intensities (~3 × 1019 W/cm2) 0.2-mm thick boron nitride (BN) target. A high p–B fusion reaction rate hence, large α-particle flux measured, thanks proton stream accelerated target’s front...

The possibility of fusion ignition in proton-Boron$^{11}$ plasma is strongly enhanced if the energy from fusion-produced $\alpha$ particles channeled to fast protons, but an environment which most protons are thermally distributed. This hybrid thermonuclear and beam-plasma offers surprisingly large advantages either purely or fusion, neither can by themselves significantly exceed bremsstrahlung...

For low carbon energy generation, a very large exchange of electricity generators is existentially vital within the next number years by power stations preferably at considerably cost than present installations. When considering million times higher nuclear per reaction chemical, usual hydrogen fusion with abundant boron fuel used for environmentally clean generators. Instead usually needed ign...

Measured highly elevated gains of proton-boron (HB11) fusion [1] confirmed the exceptional avalanche reaction process [2][3] for combination the non-thermal block ignition using ultrahigh intensity laser pulses of picoseconds duration. The ultrahigh acceleration above 10 20 cm/s 2 for plasma blocks was theoretically and numerically predicted since 1978 [4] and in measured [5] exact agreement [6...

For passive scattering proton therapy systems, neutron contamination is the main concern both from an occupational and patient safety perspective. The Mevion S250 compact proton therapy system is the first of its kind, offering an in-room cyclotron design which prompts more concern for shielding assessment. The purpose of this study was to accomplish an in-depth evaluation of both the shielding...

Recent advances in the ability to deliver boron-containing drugs to brain tumors have generated interest in -4 MeV liiacs as sources of epithemtal neutrons for radiation therapy. In addition, fast neutron therapy facilities have been studying methods to moderate their beams to take advantage of the high cross section for epithennal neutrons on boron-10. This paper describes the technical issues...

Proton-boron fusion would offer considerable advantages for the purpose of energy production as reaction is aneutronic and does not involve radioactive species. Its exploitation, however, appears to be particularly challenging due low reactivity H-11B fuel at temperatures up 100 keV. Fusion chain-reaction concepts have been proposed possible means overcome this limitation. Relevant findings are...

Nuclear reactions initiated by laser-accelerated particle beams are a promising new approach to many applications, from medical radioisotopes to aneutronic energy production. We present results demonstrating the occurrence of secondary nuclear reactions, initiated by the primary nuclear reaction products, using multicomponent targets composed of either natural boron (B) or natural boron nitride...

We investigate the proton-boron nuclear fusion cross sections under influence of intense linearly polarized monochromatic laser fields with high frequency. First, we rewrite time-dependent Schr\"{o}dinger equation using Kramers-Henneberger (KH) transformation which allows for shifting all time dependence problem into potential function. Then, that satisfy frequency limit, time-averaged scheme i...
