IMP5 - Heating, current drive and fast particles

The aim of the Integrated Modelling Project #5 on “Heating, Current Drive and Fast Particles” is to develop a package of codes for prediction and interpretation of heating, current drive and fast particle effects. The areas to be covered include ECRH, ICRH, NBI, LH, alpha particles and fast particle interaction with instabilities. The ultimate goal is to enable self-consistent simulation of heating and current drive in the presence of fast particle instabilities, especially for ITER.

A self-consistent treatment of all possible heating scenarios is a very challenging problem with current modelling capabilities. Owing to the vastly different time scales for wave propagation and the evolution of distribution functions, simulations of heating and current drive can, in general, be obtained by combining codes solving the wave fields at time slices with codes evolving the distribution functions between the time slices. The goal is to have at least one module for each physics area at two levels: one basic and less detailed enabling fast computations, and one advanced, but computationally expensive, enabling detailed computations of the distribution functions of electrons and ions during heating and current drive, ultimately incorporating non-linear effects of instabilities and their redistribution fast ions.

In 2010, the work on adapting code modules to ITM requirements will be consolidated such that essential modules are available for providing the necessary input to the transport solver ETS (IMP3). The data structures relating to the physics of Heating and Current drive and fast particle physics will be improved further. New modules will be considered and adapted to the ITM standards. When more than one module of a certain type is available, work on cross verification will start.
