The neutron burn rate (dn/dt) is routinely measured for all cryogenic implosions. The high‑performance campaign implosions have neutron yields greater than 1014 and areal densities greater than 150 mg/cm2. The neutron burn-rate analysis presented uses a model that is convolved with a response function for the OMEGA neutron temporal diagnostic. Model parameters are determined with a maximum-likelihood fit to the recorded signal. These data are used to study the time evolution of OMEGA direct-drive implosions and how the “hot spot” is formed.
