The Vigilant Power Monitor tracks the RF power delivery in your plasma processing reactor by complete and accurate of RF parameters (power, voltage, current, phase shift, impedance, harmonics...) with minimum perturbation. This probe can be inserted before or after the matching unit inside your plasma system.
We combine many proprietary innovations to offer what is probably the most advanced RF power diagnostics for plasma applications commercially available today:
- Customizable high performance electrical sensors: wideband, robust, low-perturbation and compact voltage and current sensors developed through extensive experimental work and electromagnetic modeling. The characteristics of these sensors are customized during calibration to maximize performance for your application (maximized sensitivity and power rating while minimizing the perturbation).
- High speed / high resolution cutting edge acquisition electronics with USB connectivity to sample directly and simultaneously the RF voltage and current waveforms.
- Automated highly accurate calibration process to ensure the best measurement accuracy and probe-to-probe repeatability. Our calibration process is NIST-traceable and uses the best electronic test instruments available today in a temperature and EMI controlled environment.
- Powerful and intuitive user interface software (Vigilant RF Lab) to display in real-time the measured data which transforms the PC of the user into a state of the art RF laboratory.

Low temperature plasmas (LTPs) generate a cocktail of reactive nitrogen and oxygen species (RNOS) with bactericidal activity. The RNOS however are spatially unevenly distributed in the plasma. Here we test the hypothesis that this distribution will affect the mechanisms underpinning plasma bactericidal activity focussing on the level of DNA damage in situ. For the first time, a quantitative, single cell approach was applied to assess the level of DNA damage in bacteria as a function of the radial distance from the centre of the plasma jet. Salmonella enterica on a solid, dry surface was treated with two types of LTP: an atmospheric-pressure dielectric barrier discharge plasma jet (charged and neutral species) and a radio-frequency atmospheric-pressure plasma jet (neutral species). In both cases, there was an inverse correlation between the degree of DNA damage and the radial distance from the centre of the plasma, with the highest DNA damage occurring directly under the plasma. This trend was also observed with Staphylococcus aureus. LTP-generated UV radiation was eliminated as a contributing factor. Thus valuable mechanistic information can be obtained from assays on biological material, which can inform the development of LTP as a complementary or alternative therapy for (topical) bacterial infections.
