A diagnostic method for spatial distributions of D-D and D- 3 He fusion reactions has been developed. Refinement of collimation geometry and choice of a detector and a shielding foil resulted in a drastic improvement of signal separation from noise i

The detection of hidden special nuclear materials (SNMs) is important issue for nuclear security. For this purpose, we have been developing an active neutron-based interrogation system combined with a D-D fusion neutron source, which is a compact dis

Summary form only given. In an inertial electrostatic confinement (IEC) fusion device, the so-called `beam-beam' reactions are preferable as they occur between accelerated ions at the center of the device with a rate proportional to the square of cat

We use the two-dimensional analysis code KUAD2 to simulate trajectories in an Inertial Electrostatic Confinement (IEC) device driven by a ring-shaped magnetron ion source (RS-MIS). This aims to maximize the path length λCX for ion-gas charge exchang

We present D(d, n)3 He reaction rates for a new inertial electrostatic confinement (IEC) device which aims to overcome neutralization (charge exchange) of accelerating ions by operating at D2 gas pressures of just 5?10?mPa with the aid of an internal

An inertial electrostatic confinement (IEC) fusion device driven by a ring-shaped built-in ion source is proposed and designed aiming at a reduced operating gas pressure in order to explore a possibility of a drastic enhancement in the fusion reactio
