Summary

The drum revolution of a motor-driven mycroscope micrometric eyepiece is read by means of a phototube arrangement originating calibrated electric pulses. The pulses are counted and compared by an equipment incorporating one decade counter tube channel and several condenser storage counters. Final information including track length, mean gap length and gap distribution is directly displayed by electromechanical counters. An analysis of condenser storage counters is given in the Appendix.

Riassunto

La determinazione dei vari parametri di ionizzazione in emulsioni nucleari, viene realizzata per mezzo di un apparecchio semiautomatico associato al micrometro oculare a filo microscopio. Nella misura si fa ruotare il tamburo del micrometro mediante un motore comandato a pedale dall’operatore. La rotazione del tamburo è letta da un dispositivo foto-elettrico che genera impulsi calibrati. Questi impulsi vengono contati e confrontati da un contatore decadico e da vari contatori ad accumulazione. Le grandezze misurate sono registrate da numeratori telefonici e comprendono: lunghezza totale di traccia misurata, numero dei « gap » e numero dei α gap » di lunghezza maggiore di certi valori prefissati. In appendice è riportata l’analisi dei circuiti integratori ad accumulazione.
