A novel apparatus for characterizing neutrons produced in high yield and high shot rate Inertial Fusion Energy implosions

This novel detector for characterizing IFE implosions is an alternative to the current RTNADs to measure neutron fluxes > 3x1011 neutrons/cm2 at high shot rates. The detector consists of a stack of small square metal wafers separated by thin insulating spacers. Every other wafer is held at high voltage while the remaining wafers are grounded. The stack acts as an…

3D MEA device prior to actuation. A) A completed device. B) Close-up image of a single cell culture well. The large dark metal features at the top and bottom of each cell culture well are ground electrodes, which are all electrically shorted to each other. C) Light micrograph of a single 3DMEA post-actuation. The hinge regions are plastically deformed and allow the probes to stand upright without additional supports.
A 3-dimensional in vitro flexible microelectrode array (MEA)

To replicate the physiology and functionality of tissues and organs, LLNL has developed an in vitro device that contains 3D MEAs made from flexible polymeric probes with multiple electrodes along the body of each probe. At the end of each probe body is a specially designed hinge that allows the probe to transition from lying flat to a more upright position when actuated and then…
