Summary
Phenomenological analysis of the fast pinch effect is presented and compared with some existing experimental data. It is argued that several results consistent with experiments can be derived from a general basic picture of the fast contracting process, independent of its detailed mechanism. To establish a consistent model of the pinch mechanism, it is therefore necessary to get more detailed experimental information about the dynamical behaviour of the plasma column under various initial conditions. Dimensional considerations are added in the Appendix.
Riassunto
Si presenta l’analisi fenomenologica dell’effetto di contrazione veloce e la si confronta con alcuni dati sperimentali già acquisiti. Si arguisce che parecchi risultati coerenti con gli esperimenti si possono dedurre da una rappresentazione fondamentale del processo di contrazione veloce indipendentemente dal suo meccanismo dettagliato. Allo scopo di stabilire un modello coerente del meccanismo di contrazione, è quindi necessario ottenere informazioni sperimentali più dettagliate intorno al comportamento dinamico del plasma sotto condizioni sperimentali diverse. Si aggiungono nell’Appendice delle considerazioni dimensionali.

S. Kuwabara (private communication) obtained a solution of the hydromagnetic equations of the conducting cylindrical column being compressed by the pinch magnetic field. It was found that the distance between the converging shock front and the current sheet is rather small and, therefore, the snow-plow model would be a good description of the process.
