Beam Dynamics Challenges in IFMIF | |
|
||
| The International Fusion Materials Irradiation Facility will produce a high flux (1018 n.m−2 .s−1 ) of 14 MeV neutron dedicated to characterization and study of candidate materials for future fusion reactors. To reach such a goal, a solution based on two high power cw accelerator drivers, each delivering a 125 mA deuteron beam at 40 MeV to a liquid lithium target, is foreseen. With theses accelerators, a simultaneous combination of unprecedentedly high intensity, power (2 x 5 MW) and space charge has to be addressed. In this paper, special considerations and concepts that have been developed to overcome these challenges are introduced. The methods that have been applied for beam loss prediction, optimization, beam diagnostic and characterization are presented. Then, in order to have a better understanding of beam loss mechanisms along the accelerator, massive computing activities have been launched: end-to-end particle simulations using a number of macro-particle that corresponds to the actual number of particles that will populate a bunch in the real IFMIF machine. The obtained simulation results are presented and discussed in terms of beam halo and emittance growth. | ||
