About Plasma Physics Laboratory


The Plasma Physics Laboratory at the University of Saskatchewan was established in 1958 by Dr. H. M. Skarsgard (now Emeritus Professor) and early experimental work was centred around the study of electron acceleration in the Plasma Betatron. These early experiments led to the study of plasma turbulence and some of the earliest work on turbulent heating in toroidal geometry. Successful experiments in toroidal turbulent heating, which resulted in keV electron temperature, led to the construction of STOR-1M, Canada 's first tokamak (1983) and was soon followed by a larger tokamak, STOR-M (1987) which is still active. Both machines have been used to carry out unique experiments including turbulent heating, ac (alternating current) tokamak operation, plasma biasing, anomalous transport, and Compact Torus (CT) injection. Currently the STOR-M is the only device in Canada devoted to magnetic fusion research. PPL is a member of IAEA CRP (Collaborative Research Projects) of small tokamaks.

In 2000, research on plasma based material synthesis was initiated. The Plasma Physics Laboratory is becoming a centre of carbon based materials research and its research scope is expanding rapidly with the newest addition of ion implantation program. High quality diamond grains, carbon nanotubes (CNT), and carbon nanocones, all having potentials of industrial applications, have been synthesized. Research of coating medical grade polymers with DLC (diamond-like carbon) is underway to improve haemocompatibility of artificial blood vessels in cardiovascular applications.

The Laboratory offers training of graduate students in broad programs of plasma science and plasma assisted material science. Five comprehensive graduate level courses are available and experimental programs range from tokamak physics to plasma assisted material synthesis, both in experiments and in theory.

The research contributions made by the faculty members are recognized internationally. The Laboratory is well funded by NSERC, CRC, Province, and the University.

What is Plasma

The state of matter changes from solid to liquid and then to gas as the temperature is raised. Further increase in temperature breaks Coulomb bondage between electron and nucleus and matter becomes ionized at temperature higher than about 10,000 K. (Even a candle flame at 1500 K is in the state of weakly ionized plasma as demonstrated by Faraday.) Fluorescent lamps, lightning, aurora, and electrostatic arc are a few examples of plasma discharges.

The sun and all stars are in plasma state. The high temperature in the sun is maintained by heat released in nuclear fusion reactions whereby hydrogen ions are fused to form heavier nuclei. (Uncontrolled demonstration of fusion reaction was achieved in the form of hydrogen bomb.) Active research is being carried out worldwide in order to realize fusion reactors which would provide clean, abundant energy source for future generations.

Plasma technology is indispensable in modern manufacturing and electronics industries. Tiny computer chips smaller than 1 micron size can be fabricated on silicon substrate only in plasma reactors through the process of dry etching. Novel materials, such as carbon nantotubes and diamond semiconductors, can be synthesized in plasma reactors in which chemical reactions can be accelerated by non-thermal electrons. Flat plasma display (plasma TV) and plasma headlamp have reached the stage of commercial production after decades of basic research.

Magnetic Fusion

STOR-M Tokamak (Hirose, Xiao, Singh)

The STOR-M tokamak is a research tokamak designed and built in the Laboratory for studies on plasma heating, anomalous transport, and developing novel tokamak operation modes and advanced diagnostics. After the closure of Tokamak de Varennes in 1997, STOR-M is the only device in Canada devoted to magnetic fusion. Efforts are being made to revitalize fusion research in Canada which is the only G8 country not participating in the ITER program.

Major Radius 46 cm
Minor Radius 12.5 cm
Toroidal Magnetic Field 0.5 ~ 1 T
Plasma Current 30 ~ 60 kA
Electron Density 1 ~ 3 x 10^13/cm^3
Electron Temperature 2 ~ 300 eV
Confinement Time 2 ~ 5 msec

STOR-M is equipped with a sophisticated feedback control system for horizontal and vertical plasma positions, a driver for fast rising Ohmic current, a circuit system for alternating current (ac) operation, Compact Torus Injector, and various diagnostic instruments. In the following, major experiments carried out with STOR-M are their impacts on tokamak research are described.

Alternating Current (ac) Tokamak Operation

Stable alternating current operation of a tokamak was first demonstrated in STOR-1M (1987) and subsequently reproduced in STOR-M and the Joint European Torus (JET) at 2 MA currents. Genuine steady state tokamak fusion reactors require non-Ohmic current drive. For example, injection of microwaves at the lower-hybrid resonance frequency is a well developed technology for non-inductive current drive. However, the power requirement for driving multi mega ampere tokamak currents is a significant fraction of reactor output even if a large fraction of the toroidal current is self-generated as the bootstrap current. Inductive (Ohmic) current drive is highly efficient and not subject to plasma density limitation as rf wave current drive. The principal objective of the ac operation experiments carried out on STOR-1M and STOR-M tokamaks is to demonstrate the feasibility of quasi steady state (rather than genuinely steady state) tokamak reactors. Recently, 1.5-cycle ac operation has been achieved in STOR-M without the feared accumulation of impurities during the current reversal phases.

Compact Torus Injection

Compact torus (CT) injection is an emerging new technology to fuel the core of tokamak fusion reactors in the future. Fueling technologies currently available, such as cryogenic deuterium-tritium pellet injection, may not be adequate to fuel directly the core of reactors where most fusion reactions take place. The compact torus is a fully ionized, self-confined high density plasmoid and if accelerated to a velocity larger than the Alfven velocity, it will penetrate deep into a tokamak discharge. The first non-disruptive CT injection has been demonstrated on Tokamak de Varennes using the Compact Toroid Fueller designed and fabricated in the Laboratory under a contract with the Canadian Fusion Fuels Technology Project. Subsequently, a smaller Compact Torus Injector was built with the funds provided by NSERC through the Strategic Program. It was installed on STOR-M in 1995. In addition to expected plasma fueling (increase in the plasma density), CT injection has been found to induce a phenomenon similar to the Ohmic H-mode (high confinement mode) discovered earlier on STOR-1M and STOR-M tokamaks. Similar improved confinement after CT injection has been observed on TdeV as well.

Ohmic H-Modes

H-mode is an improved confinement phase in tokamaks over nominal (L-mode) confinement. In large tokamaks with powerful supplementary heating, transition to H-mode occurs when the heating power exceeds a threshold. In STOR-1M and STOR-M tokamaks, a unique heating method, turbulent heating, developed earlier in the Laboratory for non-tokamak toroidal devices, has been applied. After the current pulse, the plasma confinement time is tripled. This observation of Ohmic H-mode was made first on STOR-1M and later on STOR-M and other tokamaks with various means including fast gas puffing and electrode biasing. The significance of the observation is in demonstrating that there is room for improved confinement even in Ohmic discharges. Concurrent with improved confinement, significant reduction of the fluctuations of plasma density and of magnetic fluctuations at the plasma edge have been observed. The plasma potential is lowered and an edge transport barrier develops. At present, the causality problem remains unresolved, that is, it is not clear plasma auto-biasing is a cause or result of improved confinement

Advanced Plasma Diagnostics

Microwave reflectometry has been developed not only for measuring the amplitude of plasma density fluctuations but also for correlation length measurements which is an important quantity in estimating the anomalous plasma diffusivity. In the core region of STOR-M, plasma density fluctuation measurement based on scattering of 2 mm microwave is being conducted with emphasis on short wavelength modes driven by the electron temperature gradient (ETG mode). X-ray tomography for fast magnetic reconnection phenomena during CT injection is planned. It is also planned to develop novel diagnostics based on far infrared lasers for the ITER through international collaboration.

Materials Processing

Plasma Assisted Materials Synthesis and Processing (Bradley, Hirose, Xiao, Yang)

Research on plasma assisted material synthesis and processing was initiated in the Laboratory four years ago. Carbon nanostructures (diamond films, carbon nanotubes (CNT), carbon nanocones) have been successfully synthesized with a newly developed ion sputtering technology which allows diamond synthesis at unusually low temperatures (as low as 250 C). Several methods have been developed for mass production of carbon nanotubes and the Laboratory is collaborating with a group in Chemical Engineering on industrial applications of CNT. In biomedical applications of diamond and related materials, DLC (diamond-like-carbon) has been coated on polymers (PTFE) to improve its haemocompatibility. (PTFE tubes used in cardiovascular applications tend to develop blood clotting if the diameter is less than 6 mm.) Haemocompatibility tests of PTFE with and without DLS coating have been conducted with human blood. Preliminary results are encouraging: DLC coating reduces platelet activation and adhesion. Field electron emission from the synthesized carbon nanostructures has also been observed. One of the long term objectives of the research is to develop a synthesis technology for diamond semiconductors. Superiority of diamond based semiconductors over silicon based semiconductors is well known but development of fabrication technology has been slow. Another area of high priority is research on super hard composite materials for applications in mechanical and nuclear engineering.

Ion Implantation (Bradley)

Plasma ion implantation is an innovative material modification technique whereby controlled quantities of desired impurities are implanted into target materials by applying high-voltage negative pulses to a target immersed in a plasma (a gas of ions and electrons) composed of the ions to be implanted. Material properties are highly dependent on the composition and distribution of impurities within the material; because it allows precisely controlled insertion of impurities at controlled depths, plasma ion implantation is one of the most versatile techniques available for the modification of material properties. A proof-of-concept high-voltage pulser has been designed and built, and is now being tested in the ICP plasma chamber recently acquired by the Laboratory. Preliminary results are encouraging. This high-voltage pulser will be used for high-dose ion implantation of a variety of sample materials, such as conventional and porous silicon, SiO2, and diamond and DLC films.

Magnetic Fusion (Hirose, Smolyakov)

Recent theoretical contributions to magnetic fusion research include: (a) linear stability analyses of the kinetic ballooning mode, electromagnetic drift type mode and finite beta effects on those modes, (b) nonlinear saturation of drift type modes, (c) strong turbulence theory, and (d) Hall MHD. A common objective of these studies is to provide a better understanding of transport in tokamaks which may ultimately lead to control of plasma instabilities and realization of more compact tokamak reactors.

Theory of inductively coupled plasmas: (Smolyakov)

Inductively coupled discharges are widely used plasma sources for material processing reactors, electrode-less RF (radio-frequency) lighting devices, and plasma spectrometers. We study nonlinear and anomalous skin effects in such discharges with a goal of developing new, more efficient plasma sources.

Magnetohydrodynamics of plasmas (Smolyakov)

Also with mass flow with applications to astrophysical plasmas. This research project aims to clarify the mechanism of the angular momentum transport due to magnetohydrodynamic instabilities in high beta plasmas such as plasmas in accretion disks around the black holes as well as to investigate whether similar instabilities may be operative in colder protostellar disks and winds. We also study the effects of convective instabilities that may exist in a stratified plasma that is too weakly ionized for magnetorotational instabilities.

Hall MHD: (Hirose, Ito)

Hall MHD approximation often provides convenient approximation for more accurate two-fluid description of high temperature plasmas. Its validity should be checked in terms of a kinetic theory. For low frequency, long wavelength MHD waves, the dispersion relation based on isotropic Hall MHD approximation has been compared with a fully kinetic dispersion relation. Significant discrepancy arises because of the isotropic plasma compressibility assumed in Hall MHD.
