SUMMARY
We present the basic properties of a simple cellular automaton (CA) model proposed
for the study of turbulence and turbulent transport in magnetically confined plasmas.
The CA is a running sandpile model, based on the Self Organized Criticality (SOC).
Such a model, despite its simplicity, provides useful insights regarding the dynamics of
magnetically confined plasmas.
1 CELLULAR AUTOMATA AND SELF ORGANIZED CRITICALITY
The purpose of this contribution is to introduce the key elements of a sandpile model,
based on the Self Organized Criticality (SOC), that could provide the computational
investigation of the dynamics for the case of magnetically confined plasmas. In this
section, it is important to give several useful definitions, such as what is a spatially
extended dynamical system, how we can study it, what is the Self Organized Critical
(SOC) state and what are the basic properties that a system has at the SOC state.
A spatially extended dynamical system is a system with both temporal and spatial
