Themainfeaturesareasfollows
Digital signalprocessingforgamma-rayspectroscopy
Suitable for multi-channel, multi-functional systems such as multi-element detectors and
anticomptonspectrometers
Spectralanalysisofscintillation(NaI(Tl),LaBr3(Ce))detectors
DigitalPulseShapingusinghighlyintegratedFPGA
Data recording viaEthernet(TCP/IP).
Figure1 DSPConfiguration
The output signal from the detector's preamplifier is directly input to the DSP and digitized by a high-speed
ADC (100 MSPS)in the DSP. The A/D converter, which is the heart of the digital pulse processing, employs
the latest 100 MHz, 14-bit high-speed, high-resolution pipelined ADC to directly digitize the signal from the
preamplifier.
Trapezoidal waveform processingisperformed by hardware calculationin FPGA. Theshapingtime required
fortrapezoidal waveform shaping is set by parameters from a PC, and peak values are digitally detected by
peakingtime(peakingtime=risetime+flattoptime)for both FASTandSLOW systems.
TheFASTandSLOWsystemsareprocessedbytwodifferentfilterblocks.
TheFASTsystemacquirestimingandperformspile-uprejection(PileupReject).
TheSLOWsystemperformsPolezeroCancelandBaselineRestorerprocessingfollowedbyenergyanalysis.
Preamplifier signals and trapezoidal waveform processing signals imported into FPGA are output via DAC
(DigitalAnalogConverter),andoperationcanbecheckedonadigitaloscilloscope.
SettingsanddataacquisitionfortheDSPareperformedbythesuppliedDSPapplication(hereinafterreferred
to as "thisapplication"). This applicationruns on Windows. The DSP communicatesonly via TCP/IP or UDP
network communication, so no special libraries are required, and the DSP can be used in non-Windows
environmentsaswell.
