1、 Product Introduction

Scintillation detector energy spectrum measurement softwareMCStarIt is a professional software used for measuring and analyzing the energy spectrum of scintillation detectors. The software mainly focuses oncompleteThe scintillation detector has functions such as energy calibration, efficiency calibration, real-time dose rate measurement, nuclide identification and energy spectrum analysis, activity analysis, etc. The energy resolution of scintillation detectors is low, and heavy peaks are severe. To use scintillation detectors to measure the contribution of different gamma rays from different nuclides to the total dose, or to measure sample activity, it is necessary to require energy spectrum analysis software with excellent energy spectrum analysis capabilities.MCStarThe biggest feature of the software is its excellent spectral analysis ability, which can be compared with passive efficiency calibration softwareNaI-CalibrationAlternatively, a standard calibration source can be used to complete the activity measurement function.

MCStarThe software is divided into two working modes: dose mode and activity mode. Users can switch between the two working modes without interfering with each other.MCStarThe dose rate mode of the software can display doses simultaneously-Time rate curve, energy spectrum information, energy deposition spectrum, detector working status, dose rate measurement data, real-time identification of nuclides, and other related information.MCStarThe activity analysis mode of the software can simultaneously display information such as spectra, peaks, and nuclides.

MCStarThe nuclide library provides3000Information on characteristic peak energies and branching ratios of multiple isotopes.

2、 Software functions and features

• Spectrometer control: The achievable parameter settings include: amplification factor, starting digital spectrum stabilization, adjusting high voltage, and displaying real time/Living time, etc;
• Energy Scale: Accurately locate peak positions through unimodal fitting, and users determine the energy corresponding to peak positions based on their prior knowledge. The software provides real-time query function for nuclide peak information;
• Peak finding: Using first and second derivative methods to find isolated peaks, and based on peak shape fitting, usingMariscottiMethod for peak searching to determine the position of heavy peaks;
• Efficiency Scale: The software provides two functions: one is to call the efficiency scale curve obtained from experimental measurements, and the other is to use a seamless connection with this softwareNaI-CalibrationThe calculation results of passive efficiency calibration software, due to the use of passive efficiency calibration, no longer require various complex calibration functions such as solid angle correction and attenuation correction in spectral analysis;
• Peak fitting: Subtract background through peak fitting, distinguish heavy peaks, and obtain net count rate. The peak shape is fitted using Gaussian function, which has excellent fitting ability for distorted peak shapes;
• Activity calculation: For different gamma peaks of the same nuclide, considering the branching ratio and efficiency scale factor, the activity is calculated by weighted average. Consider both nuclide decay and dead time correction during the activity calculation process;
• Uncertainty analysis: comprehensively calculate the uncertainty of detection efficiency and counting rate to provide the uncertainty of energy spectrum measurement results;
• Analytical nuclide library: fromENSF（Evaluated nuclear structure data filehave3000The spectral line system of multiple radioactive isotopes allows users to query spectral line information in real-time during use;
• Interface: Full Chinese interface or full English interface;
• Report output: toTXT、PDF、HTMLandXMLOutput the report in the same format.
