Argonne assists advanced reactor development with award-winning safety software
The development of modern nuclear reactor technologies relies heavily on complex software codes and computer simulations to support the design, construction, and testing of physical hardware systems. These tools allow for rigorous testing of theory and thorough verification of design under various use or transient power scenarios.

In this work, plasma is produced by arc discharge between two copper electrodes and is characterized by a movable single probe and a double Langmuir probe. The movable Langmuir single-probe technique has a reference point since it is biased with reference to one of the electrodes of the plasma-producing system. In some situations such as radio-frequency discharges, no reference point is available to bias the movable single probe. In the double-probe method, each probe is biased with respect to each other and allowed to move through the arc plasma. Depending on the magnitude of the biasing potential, charges are collected by the probes, and the probe current flowing to the circuit is calculated. After that, we obtain the electron temperature and plasma density of the arc plasma. By using the double-probe method, the value of the plasma density is more precise than with the single-probe method. Hence, the double-probe method is more appropriate than the single-probe method.
