The bMCA-Ethernet is a compact and fully digital Multichannel Analyzer (MCA) capable of performing Pulse Height Analysis (PHA) of a signal produced by a standard 14-pin PMT coupled to a scintillation detector such as NaI(Tl), LaBr3(Ce), LaCl3(Ce), CeBr3, etc. The device is powered via Ethernet using Power-over-Ethernet (PoE) technology. Connection to local networks is provided via a standard Ethernet connection. A basic software package is provided for control of the device and to acquisition and visualization of the energy spectra. A set of programming libraries are also offered which allow for easy incorporation of the bMCA-Ethernet into existing radiation systems or set ups. The programming libraries are available for both MS Windows and Linux operating systems
Overview
The bMCA-Ethernet design makes use of the latest advances in digital electronics. The device utilizes powerful digital processing techniques and algorithms to better separate the useful signal from noise and to maximize performance under high count rate conditions. The instrument also contains a miniaturized high voltage power supply optimized for low consumption that provides the necessary power for the PMT tube, including those used with large scintillation detectors. The bMCA-Ethernet has a spectral memory size of up to 4096 channels and can perform both Multi-Channel Scaling (MCS) and Pulse Height Analysis (PHA). On the data communications side, the device features lightning-fast transfer rates, with a 1024-channel spectrum being transmitted typically in less than 30 microseconds.
A basic acquisition software package is provided for managing such device operations as setup, control, data acquisition, and visualization. A digital oscilloscope function allows for the monitoring of the input and filtered pulses to aid in fine tuning the MCA parameters. The program also includes a few spectrometry related functions for processing the spectral data: calibration, ROI analysis, and peak search, to name a few.
Options
The bMCA-USB features USB interface instead of Ethernet.
bGamma Spectral Analysis Software
bGamma is a general-purpose, comprehensive, and extensive software package for gamma-ray spectrum analysis, and radionuclide identification and quantification. The software can analyze any recorded gamma-ray spectrum independently of the detector type, geometry or sample. bGamma provides all the necessary tools and functionality for performing detailed analysis of complex gamma-ray spectra and the corresponding radionuclide identification for the given sample.
