Description
The Large Volume Plasma Device (LVPD) [1] is a cylindrical shaped, linear device (length=3m,
diameter=2 ) dedicated in carrying out pulsed plasma experiments (tpulse ̃9-50ms )relevant to fusion
and Magnetospheric plasma. In the recent past, investigations are switched from active wave plasma
investigations to understanding of plasma turbulence of whistler and Electron Temperature Gradient
(ETG) nature, relevant to Magneto-spheric and fusion plasmas. In LVPD, efforts are in progress
towards enhancing plasma duration from existing 9ms to 50ms in order to cater need of carrying out
controlled experiments on Electron Temperature Gradient turbulence, a major source of plasma
loss in fusion devices by using variation in density gradient scale lengths. For this purpose, a single
console based system for LVPD operation using LabVIEW interface is developed,which will provide
timing synchronization to the operation of different subsystems and helps in the implementation
of a new Machine operation and Control System (MCS). The timing and synchronization of the
heterogeneous I&C modules in terms of centralized clock, trigger, timing and interlocking is critical.
The configured MCS consists of (a) PXI based high end instrumentation system for diagnostics
data acquisition [2], (b) Process automation system for multiple I&C controllers for slow process
[3, 4] and (c) data handling system. This paper discusses results of (a) state of art techniques for
timing and synchronization of large physics experiments, (b) centralized timing and synchronization
schema, (c) multi-module PXI module clock synchronization on multi-segment PXIe bus, (d) timing
and synchronization requirement of high current pulsed power supplies.
