The most common upgrade to a detector is the replacement of the Beryllium Window with an Ultra thin light element window to allow detection of elements down to Boron. The replacement of the FET and preamplifier can yield vastly improved resolution over original specifications in some cases and augment the improvement in light element detection.
Such upgrades can be included when a detector is repaired, or be applied as stand alone improvements to a working detector. Please inquire about what options are available for your particular detector.
Silicon Drift Detector technology has opened up further new options for detector upgrades. Watch for the future availability of this revolutionary change!
