Developer and manufacturer of DD, DT and TT industrial, linear geometry, plasma-gas target, longest life neutron generators
Longer Lifetime
More Neutrons
Better Lifecycle Costs
Robust for Industry
Industrial neutron generators with an endurance measured in years!

NSD-GRADEL-FUSION has developed a different neutron generation technology to industrial maturity. The reactor chamber is an improvement to the traditional spherical Inertial Electrostatic Confinement (IEC) device. It provides a linear geometry neutron source which has great flexibility to be designed to optimize industrial neutron applications systems.

The NSD neutron generator is a relatively simple way to achieve sustained nuclear fusion. While the possibility to scale the simple technology up to achieve more power output than input can be debated, there is no doubt that the technology provides a credible neutron source without the disadvantages of a life limiting solid target as found in common neutron tubes.
