Mapping the ignition cliff with varying Lawson parameter on N210808-like implosions

The NIF implosion experiment N210808 produced more than a MJ of fusion yield and surpassed Lawson's ignition criterion for the first time. Subsequent experiments attempting to reproduce N210808 experienced lower performance, between 400-750kJ, due to higher levels of degradations. These experiments provide a novel data set to empirically study the implosion performance versus several ignition metrics published in the literature, including generalized Lawson criteria, the ignition threshold factor (ITF), and other metrics. As expected these variable performance experiments are intermediate in metric values between previous high-performing implosions in the burning-plasma regime [Nature 601, 542 (2022)] and N210808, essentially mapping out the ignition cliff empirically and providing a novel data set to validate these ignition metrics.
