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.
