Page 119: Stabilizer
Stabilizer The Spectrum Stabilizer applies only to PHA spectrums. The stabilizer algorithm in the Lynx DSA is based on similar implementations of spectrum stabilization in other CANBERRA MCA’s, where two user-defined regions of interest or windows are used to monitor the count rate and control the stabilization.
Page 120 User settings for the spectrum stabilizer algorithm include the width of the sampling windows, a centroid channel, the spacing, a reference ratio, and correction divider. The relationship between the windows, spacing, and centroid settings are shown in the figure below. Figure 58: Relationship Between Stabilizer Functions Lynx DSA User's Manual - 9240227J...
