The planned diagnostic suite for Pacific Fusion's demonstration facility

Advances in diagnostic instrumentation have fueled the experimental progress of inertial confinement fusion (ICF) and high-energy-density (HED) plasma physics efforts in recent decades. This talk describes the status of the design of the diagnostic suite for Pacific Fusion's demonstration facility, a Z-pinch driver based on the impedance-matched Marx Generator (IMG) pulsed power architecture. Figures of merit for the diagnostic suite are discussed, in terms of measurement accuracy and precision, known failure mode sensitivity, and unknown unknown discovery. Tradeoffs in specific diagnostic instrument selection are considered from a range of perspectives, including opportunities to incorporate diagnostic shielding into facility design and to draw on progress at leading HED facilities including the NIF, OMEGA, and the Z machine. Opportunities for novel diagnostic designs to increase performance beyond the current state of the art are weighed, as well as the role that machine learning may play in the design stage of a new facility.
