Driving complex flow waveforms with a linear voice coil actuator [PDF]
Biomicrofluidics, 2019 Oscillatory and pulsatile fluid flows for use in microfluidic applications were generated using a deformable chamber driven by a low cost linear voice coil actuator. Compliance in the fluidic system originating in the deformable chamber and the fluidic tubing produced a strong frequency dependence in the relationship between the system’s input and the ...

Modeling of a linear ion trap with driving rectangular waveforms [PDF]
Journal of Mass SpectrometryAbstractWe consider the operation of a digital linear ion trap with resonant radial ejection. A sequence of rectangular voltage pulses with a dipole resonance signal is applied to the trap electrodes. The periodic waveform is piecewise constant, has zero mean, and is determined by an asymmetry parameter : one value is taken on interval and another on ,
