| Abstract: | A transient digitizer Biomation 8100 is combined with microcomputer IBM-PC/XT to form a high speed data acquisition system.The design of system hardware interface and software is described. This system has been used in experiments on multiphoton ionization and dissociation timeoff-flight(MPID-TOF)mass spectrometry of ethylene oxide(C_2H_4O) under supersonic molecular beam conditions. Also, this system is suitable for the detection of many time resolved weak signals. |
