The fuel entropy and required drive energy for an inertial confinement fusion (ICF) implosion is set by a sequence shocks that must be precisely timed to achieve ignition. This Letter reports measurements of multiple, spherical shock waves in liquid deuterium that facilitate timing ICF shocks to the required precision. These experiments produced the highest shock velocity observed in liquid deuterium (U s = 135 km/s at ~2500 GPa) and also the first observation of convergence effects on the
