Fluid Injection System for X-ray Tomography Experiments
Journal of Physics: Conference Series(2022)
摘要
Abstract Due to recent developments on synchrotron sources, time-resolved experiments are favored by fourth-generation machines. In particular, X-ray tomography beamlines can now perform complete experiments in less than one second. MOGNO, the nano and microtomography beamline at Sirius, is designed for in situ and operando experiments. The first designed and tested environmental cell is a complete injection system for porous media materials. This system is composed by a flow cell with fluid injection control and pressure feedback. The cell can be used for experiments with pore pressure up to 750 PSI. To increase the autonomy of the injection system, three syringe pumps with a volume of 15 ml are used, and the flow control is done through three independent step motors, and can vary between 30 to 10,000 µl/minute. A web application was developed to allow MOGNO users to easily control the system and read the pressure feedback.
