The particle-time-of-flight (pTOF) diagnostic, fielded alongside a wedge range-filter (WRF) proton spectrometer, will provide an absolute timing for the shock-burn weighted rho R measurements that will validate the modeling of implosion dynamics at the National Ignition Facility (NIF). In the first phase of the project, pTOF has recorded accurate bang times in cryogenic DT, DT exploding pusher, and (DHe)-He-3 implosions using DD or DT neutrons with an accuracy better than +/- 70 ps. In the second phase of the project, a deflecting magnet will be incorporated into the pTOF design for simultaneous measurements of shock-and compression-bang times in (DHe)-He-3-filled surrogate implosions using (DHe)-He-3 protons and DD-neutrons, respectively.
