Review of the Design and Operation Criteria of a DC Submerged Arc Discharge Carbon Nanostructure Synthesis Installation

Table 2

Electrode micropositioning system requirements.

Characteristics	Requirements
Velocity	Must be fine-tuned according to the arc power oscillations. The EMS must be able to work at very low speeds (∼μm·s^−1)
Feedback	Current feedback is the most effective
Stabilization methods	The use of ballast resistors is recommended according to the synthesis current used
Displacement	Large—vibrations of the electrodes. Small—frequent replacement of electrodes
Scaling	At high current densities, the design and materials used are critical. Demands the choice of an optimal reactor volume. New difficulties are to be expected
Security	The EMS must have sensors that control the limits of its displacement. To avoid short circuits and mechanical damage
