Transverse Electric Impedance of Nitella

Alternating current measurements have been taken on single Nitella cells over a frequency range from 30 to 2,500,000 cycles per second with the current flow perpendicular to the axis of the cell. The measuring cells were so constructed that electrolytes of any desired concentration could be circulated during the course of the measurements. The cellulose wall which surrounds the cell is found to...

Transverse Impedance Implementation in ORBIT

The transverse stability and broadening of the beam turn out to be the most problematic issues in the Spallation Neutron Source ring operation. The particle simulation code ORBIT, initially written for space charge and halo growth studies, now is able to cover a broad spectrum of the accumulator ring problems. Here we present an implementation of a collective force simulation due to impedance e...

Impedance-Acoustic Tomography

In this work we present a new hybrid imaging technique that combines electrical impedance tomography (EIT) with acoustic tomography. The novel technique makes use of the fact that the absorbed electrical energy inside the body raises its temperature, thus leading to expansion effects. The expansion then induces an acoustic wave which can be recorded outside the body and consequently be used to ...
