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

  • Neutron detection experiments

i-Spector is a all-in-one detector and electronics instrument based on a SiPM area (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.

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.

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 aluminium/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 (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.

  • Replacement of a PMT tube

  • Standard assembly with CsI crystal

  • Analog amplified output

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 (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.

  • Embedded 4k MCA

  • Standard assembly with CsI crystal: resolution @ 662 keV < 6 %

  • Analog output and energy spectrum

  • Basic tools for spectrum analysis

i-Spector PSD

The i-Spector PSD is a compact  gamma/neutron detection 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 based on a SiPM area (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 provides as output an amplified analog signal, a 1k channels energy spectrum and a PSD scatterplot calculated onboard.

  • Realtime Neutron/Gamma discrimination algorithm

  • Includes EJ-276 crystal

  • Pulse shape discrimination on scatterplot

  • PSD FoM ~ 2.60 in 1÷1.5 MeV range
