Environmental radioactivity is all around us. The public imagination often associates a negative feeling to this natural phenomenon. To increase the familiarity with this field CAEN designed a dedicated educational kit, based on Silicon Photomultipliers (SiPM) matrix coupled to a CsI Scintillator. Teaching and training experiences are performed starting from system calibration in terms of energy and by acquiring gamma spectra to study the emission and the composition of different samples.

What’s inside

• i-Spector- S2570B is an innovative product designed to operate as full-featured radiation detector systems for Gamma Spectroscopy. i-Spector Digital is based on a SiPM area (18x18mm), coupled to a Csl scintillator crystal, and it hosts a preamplifier stage, an integrated power supply for SiPM biasing with temperature feedback loop, a pulse shaper, a MCA based on 80 MSps 12-bit ADC and digital charge integration algorithm. The i-Spector Digital can be controlled through Ethernet and it provides as output an analog amplified signal and a 4k channels energy spectrum calculated onboard.

• To increase the familiarity with this field CAEN provides a kit of samples, suitable for gamma environmental detection. The kit is composed of an LYSO scintillating crystal, two charcoal canisters, a test sample, a fertilizer sample, a rock sample, an empty beaker, mechanics support, a portable digital pocket scale, and adhesive tape. Teaching and training experiences are performed starting from acquiring gamma spectra to study the emission and the composition of different sample and radon passive measurement.

i-Spector Digital Web Interface

The i-Spector Digital Web Interface can be easily controlled through its dedicated web-based interface with no need to install software on your PC. The user can monitor the status of the module, configure the HV and connection parameters and visualize the energy spectrum in real time.
The web-based interface allows the user to perform online analysis (area under peak, fitting, …) and download the spectrum data.
Thanks to the internal circular memory buffer, the new i-Spector Digital module (18mm – CsI ASSEMBLY) is able to store up to 1 hour of output data consisting in voltage, current and sensor temperature samples. The last 1-hour recording can then be downloaded by the web interface.
