Positron Lifetime Measurement System


 Positron lifetime measurement is used for the measurement of vacancy-type defect of semiconductor in materials field. This is an all-in-one positron lifetime measurement system with measurement device and power supply. In the lifetime measurement, the life time is calculated by using 3 Gsps, which is imported by high-speed pulse signal from two BaF2 scintillators. In the Coincidence Doppler broadening (CDB), the 2D histogram is made by wave height value of coincidence from two Ge semiconductor detectors. Additionally, these devices can be combine to be measured by AMOC, which is the correlation of lifetime and momentum.

Digital Signal Processor APN504X GbE

Front / Rear
 APN504X is a radiation measurement device with digital signal processing (DSP) for X-ray spectroscopy. APN504X does not use conventional spectroscopyamp. It directly input the preamp signal of the detector, such as SDD, Si(Li), SSD, SiPin, etc. And then, it does digital signal processing by high-speed ADC (100 MHz, 14-bit) and highly-integrated FPGA. The measurements data are Histogrum, List, and Quick scan. These data transferred to the PC via network. The application is attached without cost. Quick scan mode is a time resolution measurement. In this mode, it send histogram data to the PC by every outside trigger timing (Min. 10 ms), and PC saves data to an HDD consecutively. This mode is most suitable for the QXAFS measurement.
