Description

A new designed device for measuring the total amount of chemical stock under super criticality state is introduced. The basic principle of this device is based on the double detector-counts multiplication method. With a γ ray source placed at the middle of the reaction pot and two detectors at the top and bottom respectively, the counts from this two detectors are collected and multiplied. A self-seeking photopeak method is used to insure the system a long term stability. 238U is used as the shield material which reduces environment background obviously
