A database and meta-analysis on the performance of exploding pusher implosions conducted at OMEGA

A database of 222 exploding-pusher implosions conducted at the OMEGA laser facility is presented. The data-set consists of glass-shell capsules filled with varying pressures of D2, T2, and 3He, which were imploded using square laser pulses with intensities ranging from 1-10 × 1014 W/cm2. The database includes measurements of bang-times, ion temperatures, and yields from the DD, D3He, and DT fusion reactions. A semi-analytic exploding pusher model is introduced, which effectively captures the observed trends in the data. This model predicts that the measurements scale according to a power-law relation based on the initial capsule and laser conditions. A generalized power-law scaling relation is directly fit to each data set, providing a useful interpolation of the entire database. Overall, the database provides a valuable resource to estimating bang times, temperatures, and yields for the design of future experiments. Additionally, it provides a diverse set of data for validating more advanced implosion physics models.
