Sharing of fusion related technology among third world countries

A program to initiate experimental plasma physics in developing countries has been started as a definite step for technology sharing. Cost effectiveness of several devices has been carefully considered from the viewpoint of physical mechanisms and existing technology. From this consideration emerges the plasma focus which whilst requiring no extraordinary technology yet could be packaged into a comprehensive facility for training in plasma production, plasma dynamics, plasma diagnostic and measurement of plasma x-rays, REB and fusion neutrons, with a very wide scope for the establishment of indigeneous training and research. It is shown that the simplicity of the approach is no barrier to the richness of plasma phenomena. Indeed the simplicity allows a clear comparison of pinch devices and, for example, enables two crucial limitations of existing plasma focus devices to be singled out, the overcoming of which could result in a many-fold jump in neutron yield. Hence the need for basic studies of these limitations. These and other studies could just as well be made on small devices. The UNU Training Programme resulted from the above consideration and evolved around the UNU/ICTP PFF, a small plasma focus with interesting physics and cost-effective technology. The extension of future training programmes to cover other important devices, for example, of the FRC type such as the Rotamak could widen the scope of this sharing of plasma and fusion technology.
