An innovative method to measure particle transport both in parallel and in perpendicular to the magnetic field line for plasma confinement is proposed. The essential point is based upon the poloidally and toroidally localized particle source as a tracer. This can be realized with a double layer pellet which consists of small core as tracer such as lithium and the major outer layer of hydrogen or deuterium which is the same species as the bulk plasma. The relation between location of tracer particle deposition in the plasma and pellet size (or disturbance to the target plasma) is also shown with a parameter of pellet velocity. The results indicate that the method seems promising.
