USB-MCA: 8K Multi-Channel Analyzer with PHA and
MCS Modes and USB Interface

 

USB-MCA unit


A Multi-Channel Analyzer (MCA) is used in a nuclear spectroscopy system. To meet the requirements of a range of applications, an MCA with Universal Serial Bus interface (USB-MCA) has been developed by BARC. It supports the PHA (Pulse Height Analysis) as well as the MCS (Multi-Channel Scaling) operational modes. The support for the MCS mode has been newly implemented in the USB-MCA without altering its original PHA functionality. In the PHA mode, the resolution of the USB-MCA ranges from 256 channels to 8K channels, making it suitable for a wide range of energy spectroscopy applications from low resolution (e.g. NaI-PMT) to high resolution (e.g. HP-Ge) systems. In the MCS mode, the USB-MCA can be used for Mössbauer spectroscopy.
