Abstract :
An ion-drag pump in a vertical axisymmetric configuration was built. Different dielectric fluids were compared to establish which produced the best pumping performance. Experimental results showed that pumping performance depended on fluid properties, primarily fluid viscosity and electrical conductivity. Two fluids, dodecylbenzine and Envirotemp 200, were studied at various doping levels. In both fluids a decrease in the charge relaxation time caused a decrease in efficiency
