Telesto
The Neutron TPX3CAM

Telesto detectors are as specific to neutrons as 3He detectors with much better spatial resolution

Key Features

Scintillator-based detector concept

Efficient and sustainable detection system, avoiding high cost of operation and downtime of 3He detectors while eliminating the common scintillator issues such as afterglow and low separation power of gamma background from neutrons

Remote control

Field of view adjustments are motorized and accessible via remote control. No need to enter radiation-protected areas for manual adjustments.

High-resolution imaging

Event-based, time-resolved clustering algorithm (EMPIR) allows to generate images with a resolution of more than 1 Megapixel (Telesto Single) and more than 4 Megapixel (Telesto Quad)

Microscope mode

The optical path of LumaCAM allows to fit a motorized microscope, achieving neutron imaging resolution down to 5 µm.

The LumaCAM combines the high sensitivity and specifity of 3He detectors with the simplicity and cost-effectiveness of scintillator-based CMOS detector systems.

What is Telesto?

  • Timepix-3-based optical detector with 1.56 ns time resolution. With dual operating mode in frames (~500 fps) or event-driven” continuous mode.
  • Image intensifier with 1.56 ns time resolution. With dual operating mode in frames (~500 fps) or event-driven” continuous mode.
  • Versatile lens system with a field of view up to 100 x 100 mm (larger areas on request)
  • EMPIR Event-mode imaging software by LoskoVision
  • Ready to use in under a day, offered with a high performance PC for direct and at-line data analysis.

In collaboration with LoskoVision, we have created the plug-and-play neutron imaging system

LumaCAM

LumaCAM offers neutron researchers a complete event-based solution. The system features Telesto, specialized light tight enclosure, and adjustable Field-of-View (FoV).
The system is capable of achieving spatial resolution 3 times better than that determined by the scintillator thickness
On the left we observe single photon events measured with LumaCAM highlighting scintillator afterglow and neutron events.
In post-processing, photons are identified by grouping pixels corresponding to a single photon. Neutrons are identified by grouping photons occuring closely in space and time.

With our event-based approach you can easily distinguish between gamma ray background and actual neutron events, reduce noise output and achieve subpixel spatial resolution.
