Agronomic / Plasma-Related Requirement

Translation into Technical Parameter

Justification for Design Choice

Seed Safety (No thermal damage)

Maintaining a gas temperature < 40°C.

Use of an APPJ DBD configuration, which promotes cooling via the gas flow.

Treatment Efficacy (RONS Dose)

Generation of a high and controllable density of RONS.

Application of a high peak voltage (target > 4 kV) to create an intense electric field, essential for efficient ionization.

Treatment Uniformity

Production of a diffuse and homogeneous discharge.

Choice of an excitation frequency in the kHz range (target ~17 kHz) , optimizing the stability and homogeneity of micro-discharges in the DBD.

RONS Flux Control

Mastery of the coupled power and the plasma's chemical composition.

Design of a dedicated electronic source allowing for voltage and frequency adjustment to influence electron density and reaction pathways.

Simplicity & Low Cost

Robust and scalable architecture.

Adoption of a simplified converter topology without a voltage multiplier stage, and use of a standard cylindrical DBD geometry.
