Description
Application
All-in-one Gamma Spectrometer with digital signal processing is applicable for HPGe detector spectrometric pulses registration, amplification, digital filtration and gamma-ray spectra registration. All-in-one Gamma Spectrometer is designed as one integrated monoblock being identical to standard laboratory detection unit with inbuilt preamplifier, however it has inbuilt MCA, HV supply, etc.
Features
- All-in-one Gamma Spectrometer is fast and easy to connect the computer using Plug&Play method. Start operating the device in no more than 120 seconds
- Power supply for all parts of the spectrometer is provided by only one USB cable (USB-2 port). Maximum current less than 300 mA, voltage +5V
- All basic technical parameters of All-in-one Gamma Spectrometer are identical to any regular laboratory device produced by BSI
- Cryostat geometries and modifications are available
