The ionosphere, an ionized part of the Earth’s atmosphere, affects radio waves passing through it. The ionosphere and structures in them can cause disruptions in communication, position, navigation, and timing (CPNT) systems that rely on radio signals. These effects are scale dependent and driven by plasma turbulence (irregularities) in the ionosphere. The impact of ionospheric plasma...
Plasma Immersion Ion Implantation (PIII) is a powerful high-fluence ion implantation technique in which the target to be implanted is immersed in a plasma containing the desired ion species. PIII finds a wide variety of applications in semiconductor processing. A more recent area of application for our PIII technology is treatment of candidate materials for Plasma Facing Components (PFCs)...
Plasma Immersion Ion Implantation (PIII) consists in immersing in a plasma a negatively biased target (or electrode) with high voltage (HV) pulse in order to drive ions into the target and change the target surface structure and/or composition. This process has broad applications in the field of materials processing as well as semiconductor manufacturing. Improving PIII operational efficiency...
Plasma discharges contains two distinct zones having different physical properties, namely the quasi-neutral bulk plasma and the sheath where the quasi-neutrality does not hold, separated by an intermediate transition zone called pre-sheath [1]. In particular, the sheath has a strong impact on the entire gas discharge since it is where the plasma interacts with the boundaries. The...
Microwave plasmas are hugely-studied plasmas, they have characteristics that make them unique, they can be generated for low and high-pressures, they have relatively high densities of charged particles, and can be generated in different cavity geometries. It has been proven that pulsing a microwave discharge can be beneficial for multiple application. Indeed, power interruption reduces gas...
Cancer incidence is on the rise in Canada, and metastasis is often associated with lowered life expectancy. Bone, especially the spine, is the common site of metastasis for breast, lung and prostate cancers. Treatments for these tumors rely on heavy doses of chemotherapeutic agents and invasive surgical procedures, which usually extend onto healthy tissue. This difficult procedure often...
