This Conference has been organized around three main categories of Monte Carlo simulations: Radiation Physics, Particle Transport Simulation and Applications involving electron-photon, neutron-gamma and hadronic codes. For each of the three categories the following issues will be addressed:

Theory and methods
Physics and modelling issues
Algorithm developments
Computational science
Basic data
Experiments and measurements
Benchmarks
Status of general-purpose codes
Tools (graphics and analysis)
Applications

Several multi-disciplinary projects have emerged during the last decade which require the study of high intensity accelerator and target systems for multiple applications in different domains. For this reason, emphasis on new applications is to be paid at "Monte Carlo 2000".

Special sessions will be organized with invited speakers delivering talks on:

Past, present and future of Monte Carlo for Radiation Physics and Particle Transport Simulation
Open problems, "hot" topics, "needs & requirements", developments
Overview and "state-of-the-art" on selected topics
Prospectives of Monte Carlo simulations for the 21st century
