You have a choice between several formulas to combine two ADC parameters: Pos = Range *
right / (left + right) is a formula often used with position sensitive detectors read out from both
sides. Sum = left + right makes a sum spectrum, and Div = Range * left / right can be used to
divide two spectra. The Range and Name can be defined in the edit fields or default values will
be taken. Any such calculated spectrum can be used as a parameter for a multi parameter
spectrum. If Conditions are defined, one can be selected as a necessary Condition for
incrementing a channel in this spectra. The COPY type of spectra allows to set conditions for
copies of primary ADC spectra. HISTORY allows to display a history plot of an ADC as a new
spectra, i.e. you can see the data of the ADC as they come in versus the event number. The
length of the history plot can be defined free, just edit the Range number.
MPA-3 Server version 1.87 (Jul-21-2010): It is now possible to create spectra containing the sum
of counts from several ADC's. It can be used to create a "superdetector" from multiple smaller
detectors. It doesn't matter if the ADC's are used in single or coincidence mode, the sum spectra
is calculated from the complete single spectra. Choose Spectra... from the MPANT options menu
or the corresponding toolbar icon, click "Add Calc..." and select the "Or = Sum of counts" radio
button.
