Inertial confinement fusion system which decouples life-limited component from plant availability

An inertial confinement fusion system comprising:

• a fusion chamber for producing neutrons from a fusion reaction;
• a laser system including a plurality of lasers arranged about the fusion chamber to provide energy to the fusion chamber to initiate the fusion reaction;
• and
• a plurality of beam paths between the lasers and the fusion chamber, each beam path of the plurality of beam paths comprising a first portion which passes through a first neutron pinhole and a second portion which passes through a second neutron pinhole spaced from the first neutron pinhole, the first neutron pinhole and the second neutron pinhole arranged such that neutrons having linear trajectories propagating from the fusion chamber to the laser system do not pass through both the first and second neutron pinholes.
