Research Interests
Tokamak physics
and engineering
Designed and built
STOR-1M and STOR-M tokamaks for plasma heating and confinement studies.
Experimental programs inlcude ac (alternating current) operation, Ohmic
H-modes (high confinement modes) by turbulent edge heating and plasma
biasing,
Compact Torus injection, fluctuation measurements, and anomalous
transport.
Compact Torus
(CT) Injectors
(in collaboration with Professor C. Xiao)
The Plasma Physics
Laboratory fabricated two Compact Torus injectors, CFFTP-CTF (Canadian
Fusion Fuels Technology Project - Compact Toroid Fueller) and US-CTI
(University of Saskatchewan - Compact Torus Injector). The objective of
CT injection experiments is to develop fuelling technologies for future
tokamak fusion reactors in which the current technologies may be
inadequate for central fueling.
The CFFTP-CTF achieved the first nondisruptive CT fuelling on Tokamak
de
Varennes at CCFM (Centre canadien de fusion magnetique). US-CTI
installed on the STOR-M tokamak has unique capability of variable
injection angles. CT injection into tokamak involves rapid magnetic
reconnection, excitation of Alfven waves, and plasma heating.
Theoretical
Studies on Plasma and Instabilities and Anomalous Transport
Current and pressure
gradient driven instabilities in tokamaks and their consequences on
plasma confinement. Recent achievements include development of fully
kinetic electromagnetic integral equation codes for the ballooning and
drift type modes in tokamaks, prediction of short wavelength drift type
modes and long wavelength ion acoustic type mode which is not subject
to Landau damping. Basic theoretical studies include rigorous formulation of resonance
broadening theory without Markovian ansatz, analytic formulation of
sub-diffusive process in plasma turbulence, Hall MHD, effects of plasma
flows on instabilities, etc.
Applications of
Plasma Technologies (in collaboration with Dr. Q. Yang and
Professor C. Xiao)
Development of
plasma sources for plasma based material synthesis and surface
modification.
Recent achievements include synthesis of diamond at unusually low
temperature
(250 C), synthesis of carbon nanostructures (nanotubes, nanocones)
and their applications, e.g., carbon nanotubes as catalysts grid and
field
electron emission from carbon nanocones. Coating of biomedical polymers
with DLC (diamond-like carbon) has also been achieved. DLC coated
polymers
exhibit improved haemocompatibility compared with untreated
samples.
