1. Overview
USB-MCA (USB-multichannel analyzer) made by TechnoAP Co., Ltd. APG7300A and APG7300L (hereinafterreferred to as APG7300A (L)) are equipped with a high-speed successive approximation ADC, and operate lightweightwith only USB bus power without using an AC adapter It is a compact MCA.
The preamplifier signal from the detector is input to the spectroscope amplifier (linear amplifier), and the output
signal amplified and waveform-shaped (shaped) by the analog circuit is input to the USB-MCA. The amplitude (waveheight value, peak value) of this signal includes radiation energy information. MCA is a wave height analyzer that
detects the signal and digitally converts the maximum crest value to generate a spectrum (histogram).
"Dead time" is an indicator of MCA performance. The dead time is a time period when MCA can not measure peakvalue. New events can not be measured while events occur irregularly, such as radiation, while events are being
detected, peak detection, digitization of wave height values, memory rewriting, resetting of crest value. Normally, thedead time of MCA is said to be 1 μsec with a fast one, but the dead time of our MCA is fixed at 500 nsec.
As a method of peak detection, there is a "first peak detection mode" in addition to a general "absolute mode" in which
AD conversion is performed after peak detection. In this mode, AD conversion is started immediately after detecting
the pulse peak. Detection conversion processing can be finished within the pulse until 0.25 μs pulse shaping, which isregarded as high speed in the spectroscopic amplifier.
As measurement data, there is a "histogram" data. The histogram is the peak value. Transfer measurement data to
PC via USB cable.
Drivers and applications that run on Windows are included as software.
This manual explains the handling of our USB-MCA product.

range of the amplifier output signal of each channel is 0 to 10V. Divide this range by the abovechannel. For high energy resolution detectors such as Ge semiconductor detectors, you can obtaindata with fine resolution by selecting 16384. However, when the count is small, it takes time toacquire the peak. Since energy resolution is somewhat inferior such as NaI (Tl) scintillation
detector, if it can not be divided finely, set 4096 channels and so on.

Sets the threshold (threshold) of the waveform acquisition start timing. The unit is digit. The
setting range is 0 to 16383. Set to the value less than LLD. Waveform shaping Triggers for peakdetection and AD conversion from the timing when the input signal exceeds the threshold setting
value. If this setting is set too high, we can not acquire peak value of low energy. Conversely, if thesetting is too small, noise will be picked up. For example, when "ADC gain" is "16384", set"threshold" and "LLD" at around 100 in the beginning. While looking at the histogram "input rate
/ throughput rate", gradually lower it, it discriminates the boundary with the noise where the value
increases, and sets the threshold value slightly above it.

8. Function
8.1. Data acquisition by the GATE signal timing
When you want to acquire event data at that time from an external condition when an event occurs, input a LV-TTL
level signal to the LEMO connector "GATE" on the front panel. When it is high, it measures. When it is low, it does
not measure.
Set the external GATE input signal to slow with the DAC monitor and input it in such a range (see the figure below)that the slow output signal from the OUTPUT terminal is sufficiently covered. The guideline for the pulse width ofthe external GATE input signal is × 8 for shaping time.
Adjust so slow pole zero does not overshoot or undershoot. Keep the external GATE input signal high until the slow
output input signal goes from the baseline to the point where it exceeds the threshold level Vth.

External GATE input signal timing

NOTE: As for the external GATE input signal, at LV-TTL level, 0.8 V or less is judged as LOW level and 2.0 V or moreis judged as High level. The maximum input voltage is 5V.

8.2. Data discard by the VETO signal timing
When you want to acquire event data at that time from an external condition when an event occurs, input a LV-TTL
level signal to the LEMO connector "VETO" on the front panel. Contrary to the "GATE" function, it measures when
it is low and does not measure when it is low. The timing is the same as GATE described above.

(1) The maximum value fmax between ROI Start and ROI end in the histogram is detected.
(2) Connect the intersection point of histogram and ROI start with the intersection point of histogram and ROI end.
The background offset (offset) is calculated by finding the intersection of the straight line and the line drawn
vertically from the peak value fmax to the x axis.
(3) Calculate 1/2 of fmax minus offset and draw a straight line L1 parallel to the X axis.
(4) In order to find two points where the histogram and L1 intersect, the crossing points P1 and P2 and P3 and P4
are detected.
(5) Draw a straight line L2 connecting P1 and P2 and a straight line L3 connecting P3 and P4.
(6) Find the X coordinate x1 of the intersection of L1 and L2, and the X coordinate x2 of the intersection of L1 andL3.
(7) The difference between x2 and x1 is FWHM.

8.5. Calculation method of two-point calibration
Perform a two-point calibration using the centroid of the two energy peaks and the peak energy value to makethe unit scale of the X axis of the graph an energy (e.g., keV). One-point calibration is also possible.
Set "ROI start (keV)" and "ROI end (keV)” in the upper “ROI" in the"calibration " tab, referring to the "centroid (ch)" value of ROI1 / ROI2
displayed in "ROI "at the top of the graph. Or set the range of ROI1 andROI2 by cursor movement of the graph.

Select the radio button "keV" in "calibration" at the bottom of the"calibration" tab. Select "ROI1" and "ROI2" as the ROI in "calibration"at the bottom of the "calibration" tab.

Set the peak energy of each of ROI1 / ROI2 to "keV" for how many keV
it corresponds.

When you click the "calibration" button, the slope a and intercept b of thelinear equation y = ax + b, which are calculated by the following equation,
are automatically reflected in the lower positions of "a" and "b".

Figure 16

Before Energy Calibration (Left) After Energy Calibration (Right)a = (peak 1 - peak 2) / (centroid 1 - centroid 2)
b = y - ax
For example, using Co-60, with 1473 keV centroid 9446.99 ch. And 1332 keV centric 10729.53 ch,
a = (1332 - 1173) / (10729.53 - 9446.99) = 0.124
b = 1332 - 0.124 * 10729.53 = 1.831
As described above, “a” is automatically reflected as “0.124” and “b” is automatically reflected as “1.831”, and the unit
scale of the X axis is created by the linear expression 0.124 * ch + 1.831.
