Time-of-flight repeller circuit application in laser ablation experiment

A proposed repeller circuit system of laser ablation apparatus is applied to analyse ions produced at the process of ablation. A repeller pulse gives the possibility of improving the resolution of the detection system based on the TOF spectrometer. Improvement of the system parameters is one of the advantages of the application of programmable logical devices. Moreover, application of such devices in high-resolution counting systems increases the flexibility of the system, increases the degree of the system integration and leads directly to increasing the system reliability.
