Product Overview

The HA-BASE is a digital MCA built on large-scale integrated circuits and FPGA-based control logic, offering low power consumption and high performance. It integrates high-voltage regulation and digital signal processing, supporting spectrum analysis from low to high count rates. The unit connects directly to scintillation detectors (e.g., NaI, CsI, LaBr₃) and performs spectral analysis via dedicated MCA software.

 

Features

  • Plug-and-Play USB:​ High-speed USB communication (up to 12 Mbps) for plug-and-play operation with laptops or PCs. No external power supply is required.
  • Precision Stabilization:​ Automatic spectrum stabilization dynamically adjusts hardware/software gain based on peak shifts, effectively suppressing peak drift caused by ambient temperature fluctuations and ensuring measurement accuracy.
  • Wide Compatibility:​ High-speed digital ADC architecture adaptively optimizes the sampling frequency according to the input pulse width of various detectors.
  • Low Power Draw:​ Total device power consumption is less than 2 W.
  • Selectable Input Polarity:​ Configurable for positive or negative input pulses to meet specific application requirements.
