Sammanfattning (abstract):
Ultra-dense hydrogen H(-1) is a quantum material and the first material which is superfluid and superconductive at room temperature. This has been shown in detail for the deuterium form D(-1). With its experimentally determined H-H bond distance of normally 2.3 +/- A 0.1 pm, it is up to a factor of 10(5) denser than hydrogen ice composed of H-2 molecules. Its existence means that when hydrogen is compressed to high temperature and density, as in laser-induced nuclear inertial-confinement fusion (ICF), sudden localized spontaneous transitions to H(-1) will give spots in the material where pressure falls strongly. Such pressure drops give a non-homogeneous phase which will not ignite smoothly. The energy released by the rapid transition to H(-1) will further cause non-isotropic motion of the target material. We here propose that the instability problems which plague ICF can be circumvented by using ultra-dense hydrogen H(-1) directly as the fusion fuel.
