A modern physics facility must synchronize the operation of equipment over a wide area. The primary purpose of the site wide SNS synchronization and timing system is to synchronize the operation of the LINAC, accumulator ring and neutron choppers and to distribute appropriate timing signals to accelerator systems, including the Injector, LINAC, Accumulator(More)
There is significant interest in RHIC heavy ion collisions at √ s NN =5–50 GeV, motivated by a search for the QCD phase transition critical point. The lowest energies for this search are well below the nominal RHIC gold injection collision energy of √ s NN = 19.6 GeV. There are several operations challenges at RHIC in this regime, including longitudinal(More)
The Spallation Neutron Source (SNS) timing and Real Time Data Link (RTDL) systems are being designed and developed at Brookhaven National Laboratory (BNL), Los Alamos National Laboratory (LANL) and other SNS collaborating labs [1]. The VME-based SNS timing system is comprised of a phase locked loop (PLL) to generate a 120 Hz power line locked clock, a(More)
