Application of high voltage power supply

Apply high voltage to each detector when starting measurement.
Please check the following points before operating high voltage power supply.
* SHV cable and preamplifier power cable are correctly connected without disconnection.
* High voltage polarity (positive or negative) of the detector, maximum rated voltage, amount of voltage (V / min.) to boost
or step down in 1 minute* Confirm the notes of "APV3304 Instruction Manual" other than this instruction manual.
(1) Check the following points in the high voltage section in the advanced tab.

Figure 19: High voltage section at startup➢➢➢“output enable” is OFF and gray and invalid.
The value of sweep (V / min.) is set appropriately for the connected detector. For example, set CH1 and CH2, towhich the Germanium semiconductor detector is connected, to 500 V / min. if you want to boost 500 V per
minute. For CH3 and CH4 to which the BaF2 scintillation detector is connected, set 4000 V / min. for boosting
4000 V per minute.
If the detector does not have a bias shutdown signal, set shutdown polarity and shutdown threshold (V) to low and- (minus) 24 V for convenience. If the level of the bias shutdown signal of the channel corresponding to the front
panel SHTD 1 to SHTD 4 connector of the APV3304 is less than - (minus) 24 V, it is regarded as bias shutdown
and it cannot be applied. The level of the bias shutdown signal is displayed on bias shutdown monitor (V). An
example of bias shutdown is described in CH2 if there is no bias shutdown signal in the detector shown below

Figure 20: Status of CH2 bias shut down
The setting of CH2 is low and the bias shutdown monitor (V) is 5.3 V against (+) 6 V, which is less than 6 V, so it isdisplayed as shutdown in red. In this case, application cannot be started. In addition, when this state is reached during
the application, the voltage is stepped down according to the setting of sweep (V / min.).
➢ “output” is off and the output voltage (V) is a value near 0 (zero).

are two types: fast trigger threshold and slow trigger threshold. The fast trigger threshold is the threshold for
detecting the signal from the timing filter. The slow trigger threshold is the threshold for identifying the signal
from the waveform shaping filter.
Click the start button to start the measurement.
First, input the "fast trigger threshold" to some extent (about 50) and observe the input total rate (cps). We
gradually reduce the threshold and find a value that increases the input total rate (cps). Since its value isthe boundary between the signal and noise, set it to about + (plus) 3 to + (plus) 10 from that value. The
standard is 10 to 20. Next, input "slow trigger threshold" to some extent (about 50) and observe thethroughput rate (cps). We slowly reduce slow trigger threshold and find a value that increases throughput
rate (cps). Since its value is the boundary between the signal and noise, set it to about + (plus) 3 to + (plus)
10 from that value. The standard is 20 to 30.

*Useful information*

The counting rate is recommended to be 100cps or less in the display of throughput (cps). Up to 200 cps is a guideline.
Higher counts may increase pileup and affect the spectral shape.

If there is an abnormality in the spectrum shape, the following may be a concern.
➢ Use the high-voltage power cable and signal cable from the detector in an extended state. Do not wrap cables orbundle tightly.
➢ There are many gaps between the source and sample, or the sample and source are misaligned.

lifetime data file

Data in lifetime mode. The following files with different formats are saved at the same time.

(1) Lifetime spectrum (file name is RUN999999 _ LT_diff.dat)
Lifetime spectrum (file name is RUN999999_LT_diff_rev.dat)prn (space delimited text) format. Read data using PALSfit3 (http://palsfit.dk/) developed at DTU (Technical Universityof Denmark) in Denmark. The first line is saved in Time / bin (ns), 10 digits left-justified space format from the secondline. The one with _rev appended to the file name has a form in which the sequence of spectrum is inverted (reverse).

７． Troubleshooting
７．１．

Communication error（１） "connection error" occurs
At startup or when an error occurs in the menu "config", there is a possibility that the network is not connected
properly.

Figure 62: Device connection error at startup
Check the following points.
① Use a switching hub.
② Each port number in the [System] section in config.ini of the configuration file before startup is defined asshown below, and "IP" of each device is correctly described. For example, "192.168.10.128" for DSP. Also
start this application and confirm that the display of "IP Address" of the DSP in the advanced tab is the same.
[System]
PCConfigPort = 55000
PCStatusPort = 55001
PCDataPort = 55002
DevConfigPort = 5000
DevStatusPort = 5001
DevDataPort = 5002
SubnetMask = "255.255.255.0"
Gateway = "192.168.10.1"
ChNumber = 2③ Confirm whether it is the setting that the network information of the PC can connect to DSP.
The default values of the DSP are as follows.
192.168.10.128 (APV8002)
IP address

192.168.10.129 (APV8702)

Subnet mask
Gateway (default)

192.168.10.130 (APV3304)
255.255.255.0
192.168.10.1

Turn on the power supply while the Ethernet cable is connected.
Execute the ping command at the command prompt and check the connection between each module and
the PC.
Turn on the power of each module again and execute the ping command again.
④⑤⑥⑦

Turn off virus detection software and fire fall software.
Set the power saving function of the PC to "always ON". Sweep function etc are all turned OFF.
In the case of notebook PC etc., disable the wireless LAN function.
Set not to automatically operate Windows update or restart and make the Internet unconnected.

７．２． AMOC 3D graph malfunction(1) If there is a problem with the display of the 3D graph in the AMOC tab
disable the device by right clicking the icon of the device driver being used by the display adapter of the device manager.

Figure 62: 3D graph display error in AMOC tab

Display adapter

Figure 64: Device Invalid State for Device Manager / Display Adapter(2) Data is not displayed on the 3D graphIf the PC specifications are low, or if the momentum range or lifetime range setting range is wide (especially for the firsttime), the application may freeze or it may take 10 minutes or more to display the graph.
