VOLT-SECONDS CONSUMPTION OF JET DISCHARGES
JET has been designed to contain plasmas where alpha- particle heating is a significant part of the power balance. To do this it must be capable of operation at high enough plasma current to trap the 3.5 MeV alpha particles and for long enough for them to slow down and impart their energy to the plasma. The full performance specification of the device was for 4.8 MA plasma current. This has recently been exceeded, albeit with little flat top. The behaviour of other limiter tokamaks with intense additional heating indicates that still higher current might be necessary to obtain the thermonuclear yield required for an observable level of alpha particle heating. Therefore the volt-seconds consumption of JET discharges is of interest because it will, in part, determine the ability of the machine to meet its design goals. Also the performance of JET should guide the design of the next generation of machines such as INTOR and NET.
