With appropriate control of electrode configuration and bias, detection of SE was achieved.

There are two different types of plastic film capacitors, made with two different electrode configurations:
3.
An elegant electrode configuration is the triple probe, consisting of two electrodes biased with a fixed voltage and a third which is floating.
4.
There are various electrode configurations of equipment, the most typical using 2 current and 2 potential electrodes in a dipole-dipole array.
5.
This process will then be repeated for numerous different electrode configurations and finally result in a two-dimensional tomogram according to the image reconstruction algorithms incorporated.
6.
Numerical modeling is important to determine optimum electrode configuration in terms of pattern type, shape, and separation; power supply requirements; power synchronization; optimal target temperature; and estimated time to attain the targeted temperature.
7.
Rechargeable Zn-air batteries in a tri-electrode configuration exhibited an unprecedented small charge discharge voltage polarization of ~ 0.70 V at 20 mA / cm 3, high reversibility and stability over long charge and discharge cycles.
8.
The precise proportion of signal mix and intensity depends on the additional parameters of gas nature and pressure in conjunction with electrode configurations and bias, bearing in mind that there is no abrupt physical distinction between SE and BSE, apart from the conventional definition of the 50 eV boundary between them.

ZEPLIN-II was the first two-phase system deployed to search for dark matter in the world; it consisted of a 30 kg liquid xenon target topped by a 3 mm layer of gas in a so-called three-electrode configuration : separate electric fields were applied to the bulk of the liquid ( WIMP target ) and to the gas region above it by using an extra electrode underneath the liquid surface ( in addition to an anode grid, located above the gas, and a cathode, at the bottom of the chamber ).

There is an inner volume where the secondary electrons dominate with small or negligible BSE contribution, whilst the outer gaseous volume is acted upon mainly by the BSE . It is possible to separate the corresponding detection volumes so that near pure BSE images can be made with the GDD . The relationship of relative strength of the two signals, SE and BSE, has been worked out by detailed equations of charge distribution in the ESEM . The analysis of plane electrodes is essential in understanding the principles and requirements involved and by no means indicate the best choice of electrode configuration, as discussed in the published theory of the GDD.
