AutoCal: A method for automatic energy calibration of β-γ Systems based on a 137Cs spectrum

摘要

A method was developed and implemented that calculates energy versus channel calibrations. This method utilizes a ~(137)Cs spectrum acquired in β-γ coincidence. Both the γ singles and the β-γ coincident spectrum are utilized. The γ singles spectrum is utilized to calculate the γ detector energy versus resolution function. The Compton line in the β-γ coincidence is then used to calculate the β detector energy versus resolution function. Currently a linear regression (y = mx + b) is utilized to fit the data. However, higher order polynomials may easily be implemented if desired.
