The bMCA 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 bMCA can be easily interfaced to a typical PC or notebook via a standard USB port for further data transfer and analysis. A basic software package is provided for control of the device and the acquisition and visualization of the energy spectra. A set of programming libraries are also offered which allow for easy incorporation of the bMCA into existing radiation systems or set ups. The programming libraries are available for both MS Windows and Linux operating systems.
Overview
The bMCA design makes use of the latest advances in digital electronics. The MCA 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 bMCA implements two modes of data acquisition: Pulse Height Analysis (PHA) and Multi-Channel Scaling (MCS). The acquired spectra under PHA mode is extended for Dead Time. The device has a spectral memory size of up to 4096 channels.
The MCA 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. 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, among others.
