One-dimensional, axially resolved and time-integrated neutron images from MagLIF experiments at Sandia’s Z Pulsed Power Facility

Inertial confinement fusion (ICF) experiments conducted on the Z-Facility at Sandia present an extreme environment for neutron diagnostics with large amounts of radiation due to electromagnetic pulses and Bremsstrahlung radiation in addition to X-rays emitted from fusion processes in the experiments. The one-dimensional imager of neutrons (ODIN) has been used in ICF experiments to collect time-integrated axially resolved neutron images of the imploding targets. CR-39 track-etch detectors have used in ODIN due to their proven ability to detect neutrons in environments with harsh x-ray backgrounds. Recently, in collaboration with MIT, the ability to etch and scan CR-39 has been established at Sandia’s Z-facility. Data from ODIN collected from a subset of MagLIF experiments will be shown that illustrate this capability.
