Shrinkage of nuclear research emulsions

  • Published:
Il Nuovo Cimento (1955-1965)

Summary

A method is described for obtaining accurate values for the shrinkage factor of nuclear research emulsions, and for testing the uniformity of the shrinkage with depth. The results obtained from one plate show a shrinkage factor near the surface 6% greater than near the glass. The importance of avoiding such variations, when accurate depth measurements are required, is stressed.

Riassunto

Si descrive un metodo per ottenere accurati valori del fattore di contrazione delle emulsioni per ricerclie nucleari e per saggiare l’uniformità della oontrazione con la profondità. I risultati ottenuti con una lastra rivelano un fattore di oontrazione del 6% inaggiore presso la superficie che non vicino al vetro. Si mette in rilievo l’importanza di evitare tali variazioni quando sono richieste precise misure in profondità.
