	Fusion experiment conducted in the UK and prepared from Garching
		JET discharges will then frequently be prepared from the respective home laboratory on the basis of the recent successful test.
		JET is meanwhile the world's leading fusion device, with the plasma produced already coming close to a power plant plasma in many respects.
		JET, of course, is not intended to produce a burning plasma in the new phase of operation either.

	EUROPA - Research - Energy - - The Joint European Torus (JET)
		JET, which is a tokamak situated in Oxfordshire, UK at the Culham Science Centre, is the largest most successful fusion device in the world.
		The JET Joint Undertaking was established from June 1978 to the end of 1999 to construct and operate the JET machine.
		European fusion researchers have been able to exploit JET efficiently because they have been working for a long time in a coordinated and integrated programme, managed by the European Commission.

		A joint differs from a fault in that no displacement of the rocks on either side has taken place.
		The weathering of joints in rocks such as limestone and granite is responsible for the formation of features such as limestone pavements and tors.
		Joints in coastal rocks are often exploited by the sea to form erosion features such as caves and geos.

		JET, the Joint European Torus, is the flagship of the European Community Fusion Programme.
		The JET programme was set up to make it possible to carry out fusion tests under conditions that closely resemble those of a commercial fusion power plant.
		But only JET is able to operate using the deuterium-tritium fuel mixture planned for future commercial power stations.

	Fusion cash shortfall leaves JET grounded
		Under threat: the Joint European Torus fusion reactor may be forced to shut down by 2006.
		JET's future is in doubt because the current fusion budget at the European Union (EU) cannot both support the continent's present fusion projects and pay for the construction of ITER, the planned international magnetic fusion reactor.
		But shutting JET might be simpler than cutting funds to several of the 12 other national fusion projects that receive money from the same EU funding stream, and which could also be used to train researchers for ITER.

		Recent experiments in the joint European torus (JET) using beryllium, both as a limiter material and for gettering, have resulted in a significant extension of JET operating regimes.
		Improvements to the performance of joint European torus (JET) limiter plamas have been made by increasing the plasma current, by suppressing sawteeth, by peaking the density profile and by using beryllium evaporation and employing beryllium limiters.
		In the joint European torus (JET), 18 MW of ICR power was achieved for a few seconds and 6 MW for 20 s.

		His principal European initiative was a renewed attempt to launch EMU in 1977 (a previous attempt in the early 1970s had collapsed).
		This led to the European Monetary System in 1979, whose grandiose aims of 'lasting growth with stability' and 'a progressive return to full employment' were made to seem empty by the ensuing period of instability, stagnation and joblessness.
		A decision to take joint action in the field of foreign affairs must be agreed unanimously by the Council (not counting the votes of any state that adopts a position of 'constructive abstention').

		The Joint European Torus (JET) is the flagship of the European Programme and has been in operation since 1983.
		One of the original areas of work, that of the study of the plasma-wall interaction, has been extended to a specific new aim; to identify a means to handle the heat and particle effluxes in the next generation of fusion experiments.
		As well as progressing with its programmatic aims, JET has been highly successful in pursuing innovative areas of research and has progressed well in developing the so-called "advanced concept" modes of tokamak operation which are directed to making more compact, steady-state reactors.

	Fusion: the way ahead (March 2006) - Physics World - PhysicsWeb
		A tokamak is a doughnut-shaped vessel or torus, in which a helical magnetic field insulates charged particles in the plasma from the surrounding walls.
		JET has recently been upgraded, with various sensors now in place to improve our knowledge of properties such as the temperature, density and shape of the plasma.
		JET's size also means that the plasma current diffuses over long timescales, allowing the desired current distribution to be "frozen in" by heating shortly after the initial plasma forms.

		High-frequency electromagnetic waves are generated by oscillators (specifically, often by Gyrotrons or Klystrons) outside the torus.
		If the waves have a particular frequency (or wavelength), their energy can be transferred to the charged particles in the plasma, which in turn collide with other plasma particles, thus increasing the temperature of the bulk plasma.
		After a single series of D+T tests at JET, the largest fusion reactor yet to use this fuel, the cavity was sufficiently radioactive that remote handling needed to be used for the year following the tests.

		Although the JET Joint Undertaking (comprising Euratom, participating European countries and UKAEA as host country) has ended, further experimental work on JET will have benefits and arrangements have been agreed for UKAEA to operate the JET facilities beyond 1999, initially for three years.
		As well as the direct involvement in the JET experimental programme, the fusion programme will undertake research on two topics which are major cost drivers for the eventual decommissioning of JET: machine activation and tritium contamination.

		The receiver of the Joint European Torus (JET) energetic ion and alpha particle collective Thomson scattering diagnostic is calibrated assuming flbody emission from the torus vacuum vessel (VV) and using electron cyclotron emission (ECE).
		The 32 receiver channels are absolutely calibrated with a mechanical chopper in the quasioptical arm of the receiver, alternating the receiver view between the torus vacuum at 320 °C and room temperature.
		This calibration is noisy due to the small difference between torus and room temperatures.

	Prediction of Alfvén Eigenmode Dampings in the Joint European Torus

		It is caused by the rise of the edge magnetic shear when the plasma gets diverted, explaining why antenna excited AE have never been observed in JET in the presence of X-points.
		In summary, gyrokinetic calculations of global AE dampings predicted for JET plasmas are in good agreement with the measurements and the uncertainties obtained from these studies show to which extent predictions are possible for ITER.

		Controlled thermonuclear fusion by magnetic confinement thus became a European field of research; thereafter, national fusion research activities were brought together in a single European programme.
		The long-term objective of the Community project, which integrates all magnetic confinement fusion research performed in the EU Member States (plus Switzerland), is the joint construction of safe and environment-friendly prototype reactors, leading to the construction of economically viable power stations meeting the needs of the potential users.
		In Europe, after JET, the plan is first to build an experimental reactor (to be known as «Next Step») and later a demonstration reactor («DEMO»).
