Radiation detection for Gamma Spectroscopy and/or Neutron-Gamma Discrimination

i-Spector is an innovative product by CAEN, designed to operate as full-featured radiation detection systems for Gamma Spectroscopy and/or Neutron-Gamma Discrimination. Its profile makes this unit ideal for many portable applications where size, weight and power consumption are important constraints. Depending on the selected model, the i-Spector is suitable for a wide range of applications:
  • PMT replacement in physics experiment
  • Laboratory R&D on SiPM technology
  • Portable Gamma-Spectroscopy Industrial process monitoring
  • Environmental Monitoring
  • Handheld border control against illicit traffic of radioactive material
  • Neutron detection experiments
  • Vehicle/personnel check-point portals
i-Spector is an all-in-one detector and electronics instrument based on a SiPM area (18×18 mm2, 24×24 mm2 or 30×30 mm2), possibly coupled to a scintillation crystal suitable for the chosen application. The i-Spector integrates in a compact tube-like mechanics the detection stage, frontend electronics, an integrated power supply for SiPM biasing and, eventually, a digital chain to process onboard the incoming data. The i-Spector can be controlled via Ethernet and/or wireless communication based on LoRa standard.

A web-based GUI allows the user to set the acquisition parameters, see results on plot and perform basic data analysis.

Multiple i-Spector tubes can be connected and controlled from a single PC. The API interface allows to control multiple devices using very simple HTTP requests and JSON vectors. A cloud-based software (Rad Cloud – FREE TRIAL) allows to build a network of i-Spector units, collecting data from the detectors and displaying them on maps or interactive tables.

i-Spector is available as OEM electronics, to encourage integration in more complex detection systems, or in ASSEMBLY version, with a suitable scintillation crystal coupled to the SiPM area. The standard assembly is available with CsI for Gamma Spectroscopy and EJ-276 for Gamma-Neutron Discrimination. Other crystals can be mounted on request. The ASSEMBLY unit is enclosed in a light-tight aluminum/plastic tube ( Ø 60 mm, h 135 mm ), with the possibility to unmount the crystal holder and easily change it.
