Scale-of-Hundred Counting Unit

Abstract

A scaler unit is described which has been designed for counting pulses from Geiger-Müller counters or ionization chambers in a decimal system. The unit consists of two electronic scales-of-ten with either neon lamp or meter indication, followed by a mechanical counter. The resolving time of the scaler can be made as low as 3 μsec. and the unit is capable of recording counting rates up to 1000 per sec. It is built on a standard G.P.O. panel, suitable for rack or bench mounting.
