1. Figure 7 Relationship Between Stabilizer Functions Setup and Configuration Gain Centroid Sets the centroid in channels of the reference peak at the high end of the spectrum for gain stabilization Gain Spacing Sets the spacing in channels between the upper and lower sampling channels The sampling channels should be placed so that a shift in the reference peak reflects a sig nificant change in count rate in the sampling channels For broad peaks the spacing should be set so that the sampling channels are not on the flat part of the peak Gain Mode Enables On or disables Off the Gain Stabilization function ADC Parameters Click on the ADC button to see the dialog box in Figure 9 which shows the Adjust screen for the analog to digital converter C Amp C HWPS Figure 9 ADC Adjust Dialog Conversion Gain There is no setting for Conversion Gain in the ADC adjustment screen The number of channels in the spectrum is selected by adjusting the Input Size scroll bar in the Ac quire Setup screen page 14 Note When using Multiple Memory Groups the input memory size must be adjusted using the MID editor not the Input Size setting Lower Level Discriminator The LLD scroll bar sets the minimum pulse height that will be converted by the ADC Noise and background events that dominate the lower channels can be suppressed by moving the scroll bar to the right The MCA Adjust Screens2.

3. Upper Level Discriminator The ULD scroll bar sets the maximum pulse height that will be converted by the ADC For most work this control will be set to 100 percent Lower settings will inhibit data acquisition in the upper channels ADC Zero In most cases channel one of the spectrum is made to correspond to a zero energy in put zero intercept This means that the location of a given event in the spectrum is linearly and directly proportional to the height of the input pulse In some cases how ever the Zero control can be used to offset the spectrum by up to 1 5 to 4 5 of the ADC s current conversion gain The ADC Zero control will not normally have to be adjusted but should it become necessary remove the computer s top cover and look for the control on the top edge of the board as shown in Figure 1 on page 4 Amplifier Parameters Click on the Amp button to see the dialog box in Figure 10 which shows the adjust screen for the programmable amplifier Adjust ADC C Stab Amp HVPS rr af Abe 1 0 25 nes Coarse gain Fine gain Input mode presi 1 0 Amp Figure 10 Amplifier Adjust Dialog Coarse Gain The Amplifier s Coarse gain setting is selected from the drop down menu For most configurations it s best to choose the highest Coarse Gain which combined with the Fine Gain will produce the total desired gain Fine Gain The Fine Gain control is set with t
