Abstract

TRANSP is a time dependent transport analysis code for the study of plasma behaviour. This report contains a detailed discussion of a typical transport analysis of a JET H-mode shot. It emphasises the care that must be taken in order to get a consistent picture of plasma behaviour throughout the whole length of a pulse. Initial analysis runs of the code are made to ensure that certain important parameters such as the total plasma (diamagnetic) energy and neutron yield are of the right order. This initial stage often leads to a reappraisal of the input experimental data. A choice of transport models from those available within TRANSP is also made. Only after this preliminary stage is a full analysis performed, predictions of diagnostic measurements checked and the energy confinement analysed. A description is given of the various experimental data which can be provided as input to TRANSP either through a namelist or in a user PPF. The relative importance of specific data in a simulation is indicated. Details of some of the additional physical quantities which must be defined before running TRANSP and some of the controls that are available to determine the way in which the data are used within the code are outlined.
