Abstract
A study of the body of experimental results as well as modelling indicates that all plasma focus machines big and small operate with the same energy density both in the axial and radial phases related to an almost constant current per unit radius for all machines. This results in operational speeds and compressed plasma temperatures which are the same for all machines. It is proposed that the existing network of 3 kJ machines may be the most efficient and effective way to produce a comprehensive experimental picture of the plasma focus, apart from 'large machine' effects such as the neutron 'saturation' effect. Operational benchmarks are established for these 3 kJ machines for the purpose of standardisation to increase the effectiveness of comparative studies using different measurements obtained from different, though nearly identical machines.
