A statistical analysis is carried out of the similarity of profiles of plasma parameters: electron temperature Te, density ne, and pressure Pe, at the stage of quasi-stationary plasma current (the so called flat-top stage) of about 9000 discharges in

An integrated modelling methodology for the calculation of realistic plasma neutron sources for the JET tokamak has been developed. The computational chain comprises TRANSP plasma transport and DRESS neutron spectrum calculations, and their coupling

JET experiments have shown that the three-ion scenarios using waves in the ion cyclotron range of frequencies (ICRF) is an efficient way to build fast ion population through beam ion acceleration by radio frequency (RF) waves. Such a heating scheme i
