bMCA-E | JCS Nuclear Solutions

bMCA-E is a compact, digital Multi-Channel Analyser (MCA), which is able to perform Pulse Height Analysis (PHA) of the signal produced by a standard 14-pin standard photomultiplier coupled to a scintillation detector such as NaI(Tl), LaBr3 (Ce), LaCl3(Ce), etc.

The device is used for obtaining an energy spectrum from the photon radiation detected by the scintillator, and can be easily linked to a typical PC or notebook via a standard USB port for data transfer and further analysis.

The bMCA-E is provided with our standard software package that allows the user to control the device, and to acquire and visualise the energy spectrum. The software incorporates an advanced and easy-to-use “discovery” function that can be used to automatically detect all the bMCA’s (USB or Ethernet) on your network that are available for connection.

A set of programming libraries are also bundled with our software, which makes the incorporation of the bMCA-E into existing radiation systems or setups very easy. The programming libraries are available for both MS Windows and Linux operating systems.

Description

The bMCA-E is an advanced, fully digital, compact Multi-Channel Analyser (MCA). This device is used to process the electronic pulses produced by a photo-multiplier which is coupled to a scintillator detector. These detectors are commonly used in the detection of gamma radiation due to their high detection efficiency, medium energy resolution and relatively low price. The bMCA-U is able to produce an energy spectrum from the radiation events detected by the scintillator, storing it in the device’s memory for later retrieval and computer analysis or imported directly into the supplied software.
The bMCA-E implements two modes of data acquisition:

Pulse Height Analysis (PHA)
Multi-channel scaling (MCS)
PHA mode is regularly used in nuclear spectrometry and radiometry, while MCS is a very useful feature for following photon detections in a particular specific energy region in function of time. MCS acquisition mode is useful to both laboratory and industrial applications that make use of radioactive sources or search for radioactive materials.

The bMCA-E design uses the latest advances in digital electronics. The device utilises powerful digital processing techniques and algorithms to better separate the useful signal from noise and to maximise performance under high count rate conditions. It also contains a miniaturised high-voltage power supply optimised for low consumption that provides the necessary power for the PMT tube, including those used with large scintillator detectors. The device has a spectral memory size of up to 4096 channels and can perform MCS in addition to PHA.

Standard Software

Our standard acquisition and spectrometry software is bundled with and can be used to connect to any of our Multi-Channel Analysers for managing operations such as setup, control, data acquisition and visualisation.

A digital oscilloscope function allows the user to monitor 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 such as calibration, ROI analysis and peak search.
