An intelligent automatic gain stabilization method and apparatus for a radiation detection instrument automatically locate the position of a predetermined characteristic within an energy spectrum, automatically determine whether the characteristic is properly located, and automatically provide gain adjustment to the output of the radiation detection instrument to maintain measurement accuracy of the system.

Intelligent automatic gain stabilization for radiation detection

A variable displacement pump is controlled throughout a broad range of operating conditions between a maximum pressure, low flow rate combination and a minimum pressure, high flow rate combination even when the pump is driven by a power limited prime mover. Different relief valves set at different operating pressures are automatically selectably connected to a control port of the pump in response to the actual flow rate of the fluid pumped by the pump reaching different flow rate set points.
