Model GSpec SA – Gamma Spectroscopy System

1K MCA with High Voltage Supply & Spectroscopy Amplifier

GSpec SA is a 1K Multichannel Analyzer with HV Supply and Spectroscopy Amplifier. It is a mains operated instrument for NaI(Tl) detector based spectroscopy.

GSpec SA along with NaI(Tl) detector of Customer’s choice and Preamplifier (NETS-0M) form a complete Spectroscopy System. The whole setup has a resolution of around 7%. It is suitable for applications where low resolution of nuclides is acceptable.

GSpec SA is ideally suited for Nuclear Spectroscopy experiments carried out at Universities, Environmental Survey Labs and Health Physics Units of Nuclear Power Plants and Chemical Control Labs.

GSpec contains 1024 channel 48 MHz Wilkinson ADC with Silab Microcontroller for USB interface with PC for spectrum acquisition and data processing.

Data acquisition software is loaded on PC / Laptop and provides spectrum acquisition and display, spectrum analysis software for energy calibration, ROI selection, area calculation, peak search, peak information, spectrum smoothing and spectrum data storage on PC hard disk. High voltage supply necessary to operate scintillation detector is software programmable from 0 to 1200 volts in 256 steps. Spectroscopy amplifier gain is settable through PC.
