Research Area(s)

Tokamak Plasma Transport

Dr. Xiao's work on H-mode (improved confinement) discharge studies has contributed to better understanding of the fluctuation induced transport in a tokamak. The ohmic H-modes in STOR-M are induced by a short current pulse, electrode biasing, limited biasing, and compact torus injection.

Compact Torus Injector

Compact torus injection is an emerging new technique to fuel a large tokamak. Dr. Xiao has been responsible for design and fabrication of the University of Saskatchewan Compact Torus Injector. Tangential CT injection into STOR-M has triggered H-mode without disruption.

AC Tokamak Operation

Dr. Xiao has participated alternating current tokamak operation experiments on STOR-M. AC tokamak operation has advantages over conventional unipolar current operation because of effective Ohmic heating in a reactor.

Plasma Diagnostics

Dr. Xiao has expertise in plasma diagnostic instruments including Langmuir probes, magnetic probes, microwave and He-Ne laser interferometers, neutral beam, SXR detectors, spectroscopy, and pulsed power supply technology.

Applied Plasma Physics and Technology

Dr. Xiao is also working on plasma assisted syntheses of carbon-based materials such as carbon nanotubes and diamond films using hot filament and microwave CVD devices. The field electron emission properties of the films are also investigated. A dense plasma focus device has been built to investigate the feasibility of activation of short-lived isotopes used for medical imaging.
