AVATAR-SP Digital Spectrum Decoding Multi-Channel Analyzer

Description：

AVATAR-SP digital spectrum decoding multi-channel system is a hybrid system with built-in digital multi-channel function and energy spectrum analysis function. It is mainly used to adapt to various scintillation detectors such as NaI, LaBr3, BGO, etc. for energy spectrum reading. The waveform full sampling technology directly digitizes the preamplifier signal, and integrates high-voltage control, zero adjustment, gain adjustment, and temperature acquisition internally. The obtained spectral data completes the spectrum decoding function in multiple channels.The built-in peak stabilization program can maintain the stability of peak position for a long time. It uses Gaussian fitting and step function to calculate the net peak area, and can return the spectral results in real time. Users can identify nuclides and calculate activity based on the spectral results.
