Abstract
Advances in high power ICF drivers will enable the compression of targets to ρR values above 0.2 g/cm2. At such ρR values only hard X-rays, γ’s neutrons can escape from the target and provide data about the implosion process. Consequently, several neutron based diagnostics schemes have been developed throughout the years for high ρR application. For example, a neutron time-of-flight device can measure the average burning fuel temperature, while the ρR of the fuel and the tamper can be roughly deduced from neutron activation techniques. Still, the ultimate goal of a temporal and spatial resolved 3-D display of the target density and temperature cannot be met with current technology. However, some recent advances in neutron diagnostic can potentially resolve several of the difficulties faced in achieving this goal. These schemes along with their limitations and capabilities are discussed.
