Nuclear Fusion with Polarized Fuel

G. Ciullo; R. Engels; A. Vasilyev; Markus Büscher

n, where V is either ω or φ. Using a model where the parameters are largely constrained by other sources, we find that, although small, crossed channel final state interaction can influence the amplitudes considerably, in special areas of phase space. These results cast doubt on the inapplicability of unitarity constraints on production amplitudes as recently claimed in the literature.

A Permanent-Magnet Array to Maintain 3 He Gas Polarization Inside a Glass Vessel for Applications in High-Energy Laser Physics

We report on the successful use of a laser-driven few-MeV proton source to measure the differential cross section of a hadronic scattering reaction as well as on the measurement and simulation study of polarization observables of the laser-accelerated charged particle beams. These investigations were carried out with thin foil targets, illuminated by 100 TW laser pulses at the Arcturus laser facility; the polarization measurement is based on the spin dependence of hadronic proton scattering off nuclei in a Silicon target. We find proton beam polarizations consistent with zero magnitude which indicates that for these particular laser-target parameters the particle spins are not aligned by the strong magnetic fields inside the laser-generated plasmas.

Particle acceleration in laser-induced relativistic plasmas ? a novel approach for polarized sources?

Markus Büscher; I Engin; Paul Gibbon; A Karmakar; A. Lehrach; Th Mennicken; N Raab; Monika Toncian; T. Toncian; O. Willi

We designed and tested an array of permanent magnets (PMA) consisting of two rings with a Halbach-type magnetization pattern, which are stacked at an optimum distance such that its field homogeneity is sufficiently high to maintain the nuclear polarization of 3He gas for future laser experiments. The design included the magnetic layout, the selection of appropriate magnets, and the calculation of the expected relaxation time for the polarized gas. After assembly, we measured the magnetic field in the center region of the PMA. We transferred polarized gas samples from the magnetized transport box into the PMA and determined the relaxation time with four magnetic field sensors in a gradiometric arrangement, detecting the decay of the stray field of the polarized gas on the order of 100 nT in a background field of 1.3 mT. The extracted polarization lifetime of about 21 h is sufficient for the planned experiments at high-power laser facilities.

The Forschungszentrum Jülich (FZJ) pursues interdisciplinary research that aims to solve the grand challenges facing society in the fields of health, energy, and the environment, and also information technologies. In combination with its two key competencies—physics and supercomputing—work at Jülich focuses on both long-term, fundamental, and multidisciplinary contributions to science and technology as well as on specific technological applications. With a staff of about 4,500, Jülich—a member of the Helmholtz Association—is one of the largest research centers in Europe. Located south-east of the city of Jülich it is close to the center of a triangle formed by the German cities of Aachen, Düsseldorf, and Cologne.

The physics of laser-plasma interactions has undergone dramatic improvements in recent years. By directing a multi-TW, ultrashort laser pulse onto a thin foil or a gas jet, it is nowadays possible to produce multi-MeV proton, ion and electron beams. Although much progress has been made in characterizing and improving the quality of such laser-generated beams, it is still an untouched issue whether the laser-generated beams are or can be spin-polarized and, thus, whether laser-based polarized sources are conceivable. To this end, one may either think of a selection of certain spin states through the huge magnetic field gradients that are inherently generated in the laser-generated plasmas, or of pre-polarized target particles which maintain their polarization during the rapid acceleration procedure. We have developed a method to measure the degree of polarization of protons that have been accelerated at the 200 TW laser facility ARCturus at Dusseldorf University. As a next step, measurements with unpolarized H2 (for proton acceleration) and 3He gas (for 3He ions) are planned and, finally, pre-polarized 3He will be used.
