Fig. 3From: Electric ion dispersion as a new type of mass spectrometer a, b Plot of y-position (Fig a) and y-velocity (Fig b) over time for particle of mass m=m p . The “sharp” transition regions are where the particles enter and exit the device separating two regions of essentially constant velocity. The transition regions themselves experience a very small acceleration. The solid blue curves represent the particle being outside of the device while the red dashed curve represents the particle inside of the deviceBack to article page
