Overview

i-Spector is an innovative product 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 chosen 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 borders control against illicit traffic of radioactive material
  • Neutron detection experiments
  • Vehicle/personnel chek-point portals.

i-Spector is a 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 sofware (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.

i-Spector

i-Spector is a fully-integrated compact tube designed to replace existing systems based on PMTs. It is based on a SiPM area (18×18, 24×24 or 30×30 mm2) with preamplifier stage and integrated power supply for SiPM biasing with temperature feedback. The i-Spector can be controlled through Ethernet. The output is a fast analog signal that can be digitized or processed with a common Digitizer, MCA or discriminator/TDC chains.

i-Spector PLUS model integrates an additional Timing Unit that is able to correlate the detector signal with external signals. It is designed to perform event timestamping, ToF measurements, coincidence between multiple i-Spector modules and photon counting.

i-Spector Digital

The i-Spector Digital is a fully-integrated, tube-like  Gamma Spectrometer designed to operate as a complete radiation detection system, with integrated MCA and optional wireless connectivity. Its profile makes it ideal for many portable applications where size, weight and power consumption are important constraints.

i-Spector Digital is based on a SiPM area (18×18, 24×24 or 30×30 mm2), eventually coupled to a suitable scintillation 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.

i-Spector LoRa integrates an additional radiocommunication interface which is ready to connect to LoRaWAN networks for IoT and environmental monitoring applications.

A cloud server (Rad Cloud) allows to collect data from multiple i-Spector Digital and display them on maps or interactive tables.

i-Spector PSD

The i-Spector PSD is a compact  neutron detector system based on SiPM, featuring high detection efficiency and wide dynamic range. It is a valuable solution for compact and lightweight instruments for radioactive material identification or environmental measurements.

i-Spector PSD is a solution dedicated to those users that need the versatility of a  compact  system for neutron/gamma discrimination. Its profile makes it ideal for many portable applications where size, weight and power consumption are important constraints. For example, it is suitable for hand-held instruments for border control against illicit traffic of radioactive material.

i-Spector PSD is based on a SiPM area (12×12 or 24×24 mm2) coupled to a fast neutron-sensitive plastic scintillation crystal (EJ-276). The unit is full-featured with a preamplifier stage, integrated HV for SiPM biasing, a 250 MSps 12-bit ADC and a microcontroller to perform real-time pulse shape analysis. It can be controlled through Ethernet and it provides as output an amplified analog signal, a 4k channels energy spectrum and a PSD scatterplot calculated onboard.

We obtained a Figure of Merit (FoM) for Gamma/Neutron discrimination of 2.50 in the 1÷1.5 MeV energy range.
