Hexagon is a compact, stand-alone dual digital 32k MCA, available in desktop form factor. It is designed for high energy resolution semiconductor detectors, like HPGe and SDD.
Thanks to the two input simultaneous acquisition, the module is able to manage coincidence and anti-coincidence logic between detectors, allowing the user, for example, to easily take advantage of background rejection or anti-Compton techniques.
The module has been designed to operate as a scalable multi-input, multi-board acquisition system, offering synchronization capabilities.
The Hexagon houses USB 2.0 and Ethernet interfaces. USB 2.0 allows data transfers up to 30 MB/s.
