Introduction:
The scintillation energy spectroscopy measurement system is a full-featured general-purpose gamma energy spectroscopy system, which uses scintillators such as NaI (Tl), LaBr3 (Ce) or CeBr3 as detectors. The system also includes photomultiplier tube (PMT), preamplifier (PA), high-performance UltraBase socket type multi-channel analyzer/DMCA-PCIE8k plug-in type multi-channel analysis card, spectrum stabilization unit, high-voltage power supply, etc. Connect to the computer through the USB or Ethernet port interface, thus quickly forming a high-efficiency energy spectrum measurement system.
The manufacturer can provide the dynamic link library of the API interface, and the user can directly call the library files in the system according to their own application scenarios to compile their own software, avoiding a long development cycle and high investment costs.
The system can be used in radiation environment monitoring, on-site sample analysis, vehicle/airborne radioactivity survey, on-line monitoring of radioactive pipeline process lines, scientific research experiments and user customization and other applications.
Features:
1) Highly integrated digital multi-channel, integrating PMT, preamplifier, high-voltage unit and multi-channel analyzer, etc.;
2) The advanced digital nuclear pulse signal enhancement processing technology (NPSE) is used to effectively improve the energy resolution of the system, thereby enhancing the ability of nuclide analysis and identification;
3) System versatility and plasticity. Combined with relatively simple structural improvements, the system is suitable for laboratory and outdoor environments, routine monitoring and emergency response.
