Abstract :
A high resolution neutron imaging system (NIS) is developed and tested on the OMEGA laser facility for inertial confinement fusion (ICF) experiments. This diagnostic uses a coded imaging technique with a high resolution neutron camera. Over the past few years, this detector was improved and neutron images can now be acquired on OMEGA with a 20 μm spatial resolution in the source plane and good signal to noise ratio with both a penumbral and an annular imaging technique.
