１．２． Features
The main features are as follows.
・Digital signal processing for gamma-ray/X-ray spectroscopy
・Suitable for multi-channel, multi-functional systems such as HPGe semiconductor detectors,
multi-element semiconductor detectors, and anticompton spectrometers
・Spectral analysis of scintillation (NaI(Tl), LaBr3(Ce)) detectors
・Digital Pulse Shaping using highly integrated FPGA
・Data recording via Ethernet (TCP/IP)
Figure1 DSPconfigurations
The output signal from the detector's preamplifier is directly input to the board and digitized by a
high-speed ADC (100MSPS) in the DSP. The A/D converter, which is the heart of the digital pulse
processing, uses the latest 100 MHz, 16 Bit high-speed, high-resolution pipeline type ADC to
directly digitize the signal from the preamplifier.
Trapezoidal waveform processing is performed by hardware operation in FPGA. The shaping time
required for trapezoidal waveform shaping is set by parameters from a PC, and both FAST and
SLOW systems digitally detect peak values using peaking time (peakingtime = rise time + flat top
time).
The FAST and SLOW systems are processed by two different filter blocks.
The FAST system acquires timing and performs pile-up rejection (Pile up Reject).
The SLOW system performs Pole zero Cancel and Baseline Restorer processing followed by
energy analysis.
Preamplifier signals and trapezoidal waveform processing signals imported into FPGA are output
via DAC (Digital Analog Converter), and operation can be checked on a digital oscilloscope.
Settings and data acquisition for the DSP are performed by the supplied DSP application
(hereinafter referred to as "this application"). This application runs on Windows. The DSP
