  The High Repetition-Rate Advanced Petawatt Laser System (HAPLS) forms part of the European Union's Extreme Light Infrastructure Beamlines project (ELI-Beamlines) which will be the first international laser research infrastructure of its kind. HAPLS will generate peak powers greater than one petawatt at a repetition rate of 10 Hz with 30fs wide pulses. ELI will enable unprecedented techniques for many diverse areas of research. HAPLS requires a high-precision timing system that operates either independently or synchronized with ELI's system. Greenfield Technology, a producer of mature picosecond timing systems for several years, has been hired by LLNL* to provide just such a timing system. It consists of a central Master Timing Generator (MTG) that generates and transmits serial data streams over an optical network that synchronizes local multi-channel delay generators which generate trigger pulses to a resolution of 1ps. The MTG is phase-locked to an external 80 MHz reference that ensures a jitter of less than 10ps. The various qualities and functions of this timing system are presented including the LabVIEW interface and precision phase locking to the 80MHz reference.
*LLNL is operated by Lawrence Livermore National Security, LLC, for the U.S. Department of Energy, National Nuclear Security Administration under Contract DE-AC52-07NA27344.
