Abstract

An important requirement for a fusion experiment like JET is the accurate and reliable measurement of the plasma conditions. In a magnetically confined plasma there are many quantities to be measured in order to characterise the plasma and to compare experiment with theory. A considerable effort has been invested into providing the JET experiment with a comprehensive set of diagnostics. Particular emphasis has been placed on making measurement of the different plasma parameters simultaneously within a single discharge, in order to avoid problems of irreproducibility. Considerable care has been taken during the design and construction of these diagnostic systems to ensure that they are consistent with the high standards of engineering of the other systems of the JET machine. Many of the systems described in this paper were operated in a preliminary version for the first operation of JET in 1983, and since then they have been refined and brought into full operation. Most of these systems are now capable of reliable and automatic operation, allowing the scientific personnel to concentrate on interpretation of data. A few systems including the neutron systems specifically intended for the later phases of JET's programme are still in construction and will be installed within the next few years.
