Multi Channel Analyzer MS Hybrid

DESCRIPTION

Amplification, optimal filtering, analog-digital conversion of signal from semiconductor detectors of ionizing radiation, the accumulation of spectra and transfer to a PC via an RS-232 or USB, the formation of the necessary voltages for detecting units (high voltage for semiconductor detector and power for preamplifier). Hybrid is designed to work with HPGe or SiLi detectors produced by Baltic Scientific Instruments or other manufacturers.

Digital Multi Channel Analyzer HEXAGON

DESCRIPTION

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.

Digital Miniature Multi Channel Analyzer MCA 527

DESCRIPTION

The MCA527 is a battery powered high performance 16K Multi-Channel Analyzer/Multi-Channel Scaler module with the performance of a laboratory grade MCA. High voltage supply for detector and preamplifier power supply are integrated as well as an internal coarse amplifier and digital filtering and analysis. Together with a detector it forms a small-size gamma spectroscopy system, which is well suited to the demands of field measurements for international safeguards, environmental monitoring, nuclear waste treatment facilities, radioactive transport control and similar applications.
