The XS100 is X-ray spectrometer with SDD detector (30 mm2), which is a high-resolution. The XS100 was downsizing by integrated combination of SDD, DSP, high-voltage power supply and Peltier device. The pre-amplifier signal from SDD detector was carried out DSP processing by ADC (100 MHz, 14 bit) and FPGA. That data is transferred to a PC by USB connection. It was carried out transistor reset processing in an appropriate way. Therefore, it has substantially-improve the throughput.

Spectrum Survay meter TS215


The TS215 is a spectra survey meter with energy compensated for gamma-ray with 1.5 inch LaBr3(Ce) scintillator. It can be used for dose rate measurement in a wide range. The different time constant chart will be indicated on the LCD color display. Therefore we can check time variation of dose rate and energy spectra in real time. It is possible to the data transfer to PC by using an add-on interface in an optional feature.

 Started selling a digital spectra meter, "DS100" and "DS100L". [6 August 2012]
We will release a digital spectrometer "DS100", which is combined high-voltage power supply, preamplifier, and MCA (multi-channel analyzer). Additionally, "DS100L" is "DS100" with a LaBr3(Ce) scintillation detector.
 
DS100 DS100L
DS100 with LaBr3(Ce) scintillation detector
The target detectors are a semiconductor detector (Ge, CdTe, Si), a scintillation detector (LaBr3(Ce), NaI(Tl), CsI(Tl)) and the other. It is a common specification that the high-voltage power supply is ±0 〜 4000V, and preamplifier is ±12V and ±24V (compliant with standard NIM). The preamplifier of the detector signal direct input to DS100, the digital signal processing is performed by a high-speed ADC (100MHz・14Bit) and a highly integrated FPGA. The results of digital signal processing was shown a histogram by MCA function. The data is transferred to PC via a USB cable. The resolution is 1.7keV in 1.33MeV at Ge semiconductor detector and 2.8 to 3.5% at 662keV in LaBr3(Ce) scintillator, and throughput is more than 100kcps.
