Design of monitoring and measurement system for the supersonic diffuser of COIL

A realtime data acquisition system is designed to investigate the supersonic diffuser in COIL. The hardware is based on EVOC PCI data acquiring board and the software is developed under VB6.0. By this system, high precision of data acquisition can be achieved for the measurement of flow pressure in the supersonic diffuser. It will benefit the optimum design of the supersonic diffuser and the miniaturization and practicality of COIL.
