A Modified Decade Scaler: Final Report on Project Authorization Number CMR-3-5,

Abstract

An automatic decade scaler which operates for a fixed number of counts has been developed for use with a Geiger tube. The elapsed counting time is read by a 115V AC clock to 0.01 minute. Manual operation is provided to allow the scaler to be run for a fixed time interval in which case every 10,000 counts are recorded by a Cyclotron recording meter. The instrument has a two pulse resolution time of 25 microseconds. Four decades in cascade are used in the scaler, one of which has a resolution time of 8 microseconds; the other three, a resolution time of 30 microseconds. Ten neon bulbs are used in each decade to indicate the count.
