Abstract
At Livermore we are interested in imaging the thermonuclear burn region of fusion targets irradiated at our Nova laser facility. We expect compressed core diameters to be 10’s of microns, and would like images with better than 10-µm resolution. Alpha particle images provided the first direct information about the thermonuclear burn geometry in thin walled exploding pusher targets [1]. In future high density target experiments, only highly penetrating radiations like the 14-Mev neutrons will escape the target core to provide information about the burn region [2]. To make the measurement with a neutron “pinhole” camera requires a 10-µm pinhole through about 10 cm of material and 1014 to 1015 source neutrons [3].
Work performed under the auspices of the U. S. Department of Energy by the Lawrence Livermore National Laboratory under contract number W-7405-ENG-48.
