A dedicated data acquisition system for ion velocity measurements of laser produced plasmas

Abstract

122-126This paper describes the design of a multi-channel 25 MSPS (mega samples per second) data acquisition system. The approach is based on a flash analog to digital converter and a FIFO (first in first out) memory. This system is used for acquiring the ion velocity profiles using Langmuir probes in laser plasma in teraction experiments carried out using a high power Nd:glass laser. These profiles are displayed on the personal computer monitor and processed for calculating the ion velocities. The digitized data is stored for further analysis.</span
