At the present time, most of the world's energy is produced by burning fossil fuels like coal, gas and oil, which are limited to some 100-200 years of use. However, already in 50 years from now, the world population will rise to about 10 billion people, and the energy consumption is estimated to rise to a value that is approximately three times higher than what is being consumed now. Thus, continuation of the burning of fossil fuels for energy production could pose a serious problem in the future. Moreover, the massive use of fossil fuels might lead to the release of giant quantities of CO2 in to the atmosphere. CO2 is a greenhouse gas that leads to an increased absorption of the infrared radiation re-emitted by the Earth. This explains the importance of renewable energy sources, such as windmills, solar panel power plants, biogas power factories and many others, to overcome the abovementioned environmental effects. For a number of reasons, however, the renewable energy sources can only cover approximately several tens of percent of the world energy need and therefore it is important to explore also other forms of electricity production.
Controlled thermonuclear fusion can fulfill the demand of mankind to have an inexhaustible source of energy that does not cause any serious environmental pollution. To produce energy, two light nuclei must be brought close enough together to overcome the so-called Coulomb barrier such they can fuse. The kinetic energy of these nuclei should be high enough to cross the barrier and arrive in the zone very close to the nucleus, where the nuclear forces are larger than the electrostatic repulsion. In the nuclear reaction, according to the famous Einstein equation E = mc^2, a small portion of mass is released in the form of energy.
The most accessible fusion reaction is the reaction involving deuterium (D) and tritium (T). It is on this reaction that most research on controlled fusion is being conducted.
The temperature (which measures the interaction energy) required for nuclear fusion reactions should exceed a hundred million degrees. At this temperature electrons are detached from the nucleus. Thus, atoms are ionized and form a gas of ions and electrons. This is the fourth aggregate state of matter called plasma. Plasma is the most widespread form of matter in the Universe and exists in a large diversity of objects.
A star (and our Sun in particular) starts to shine when, under the action of gravity, the matter inside it attains sufficiently high densities and temperatures to set off thermonuclear reactions. In this way the natural tendency of the plasma of dispersing and, therefore, cooling down is balanced by the gravitational force. On Earth, however, gravitational confinement of plasma is impossible. Two possible scenarios are being studied to generate fusion energy from thermonuclear reactions: inertial confinement, in which a small volume of matter is being raised to very high density and temperature in a short time, and magnetic confinement, in which a hot plasma is confined by a force from external magnetic fields. Experimental devices that are based on the idea of magnetic confinement seem to be the most promising at this time.
The aim in thermonuclear fusion research is to build a continuously operating reactor in which the energy released by the fusion reactions is sufficiently high to keep the plasma hot and to produce more fusion reactions.
The most efficient magnetic configuration so far has been invented in the 1950's by Soviet scientists. This device has been called "Tokamak", which is an acronym for the Russian name "TOroidal'naya KAmera MAGnitnaya"; the letter "G" has been substituted to "K" to ease the pronunciation (see the Figure below). Tokamaks have rapidly replaced many other magnetic configurations in the research of controlled nuclear fusion. Today, only stellarators are still considered as a possible alternative to the tokamaks, albeit that their present performance is significantly lower than that of tokamaks.

Nowadays, the largest tokamak in the World is JET (Joint European Torus) in the United Kingdom. In the coming years, the construction of an even larger machine, ITER (Latin word for "The way"), that will produce a fusion plasma and demonstrate the feasibility of a future power plant, will start in Cadarache, France.

Charged particles in a plasma can be subject to natural oscillations. Charged particles gyrate around the magnetic field lines due to the Lorentz force. This force is always perpendicular to the local magnetic field direction and to the particle velocity vector. If the particle is an electron, its rotation frequency is called the electron cyclotron (EC) frequency.
Because the electrons gyrate around the magnetic field lines, confining the plasma, they are accelerating and emit radiation at the basic electron cyclotron frequency and its harmonics due to the periodic movement. The electron cyclotron frequency is proportional to the magnetic field strenght and, hence, to the radial position in the tokamak.

This ECE radiation can be used to evaluate the electron temperature at different plasma positions. One should take into account, however, that there is a certain frequency range limit due to the 2nd and 3rd harmonics overlap at the higher frequencies, if ECE radiation is measured at the Low Field Side of a tokamak. The 3rd harmonic ECE is also available for detection, although one always needs to correct the measured radiation temperature for the optical thickness and wall reflections.

Studies of broadband temperature fluctuations played an important role in many fusion devices, since they are thought to be related to turbulent transport in magnetically confined plasmas.
The optically thick ECE signal (that is a function of time t) S(t), as measured by each radiometer channel, consists of an average Sav and a fluctuation Sfluct part that are proportional to the average plasma temperature Tav , and to its fluctuating component Tfluct plus the statistical radiation noise (also referred to as: intensity fluctuations, thermal noise, wave noise, or photon noise) N. The radiation noise has nothing to do with the electron temperature and "real" temperature fluctuations:

S(t) = Sav + Sfluct ~ Tav + Tfluct + N

To measure the average amplitude of temperature fluctuations in tokamak plasmas of smaller than 1 - 2%, one needs to get rid of the thermal noise N. This can be achieved by cross-correlation of two ECE signals whose temperature fluctuations are correlated while the noise fluctuations are uncorrelated. One possibility is to observe the same plasma volume from two different directions, another by using two sample volumes that only partly overlap (see Figure below). Mathematically, the correlation between two signals is the measure of the degree to which the two signals are similar. The cross-correlation method does not require ECE signals to be absolutely calibrated.

For two neighbouring channels (radial position r1 ≠ r2) of a radiometer with a single line of sight, temperature fluctuations are partly correlated if the correlation length of these "true" fluctuations is sufficiently large. The thermal noise is uncorrelated and will not contribute to the fluctuation spectrum. It is possible to choose two separated ECE frequency bands such that the two corresponding radial positions r1 and r2 are still coincident within the natural line width of ECE. In other words, disjoint frequencies are coming from the same sample volume to observe coherent temperature fluctuations.
