ADVACAM offers cameras and solutions for multiple other applications, such as electron microscopy, crystallography, neutron imaging, localization of sources of ionizing radiation, charged particle tracking, and dosimetry for cancer therapy. In addition, many cameras are being used in basic research, such as at CERN's LHC accelerator, and for education on radiation and its properties in schools and universities.


Localizing Ionizing Radiation Sources with Compton Camera-Equipped Autonomous Drones. Our detectors working in Compton camera mode provide the direction where the radiation comes from. That means there is no need to map the entire area slowly and systematically.

The RaDron project aims to detect, identify, and locate radiation sources with potential applications in addressing nuclear plant accidents or preventing terrorist attacks. This project is a collaboration between three world-class Czech teams: ADVACAM with its advanced detectors, the Faculty of Electrical Engineering CTU with its autonomous drones, and the Czech Metrology Institute.

The researchers have tested several strategies for autonomous localization of the static and moving source of radiation. According to the experiments, a relatively weak Cesium-137 source can be localized within 1-2 minutes in 1000 m2. In contrast to existing technology, our compact sensors can give direction toward the radiation source, not only detecting its presence. That makes the search process much faster – the order of magnitude, at least.

Once the Compton camera detects sufficient data, a 3D hypothesis of the radiation source’s position is calculated. The drone then flies directly toward the head, constantly using incoming data to refine its position. This approach significantly expedites the localization of radionuclide sources or radiation hotspots.

The presented concept can be used within many rescue operations, such as:

  • accident of a car carrying radioactive material
  • fire in the radiological department of a hospital
  • nuclear accidents
  • searching for a stolen or lost radiation source

Our drone is equipped with ADVACAM’s MiniPIX TPX3 detector, featuring a 2mm-thick CdTe sensor that operates in a specialized “Compton camera” mode. The data collected by the detector help determine the direction of the radiation, enabling the drone to navigate toward the radiation source. The control system for autonomous drones, known as the “MRS UAV System,” is being developed at CTU in Prague.


X-ray crystallography is used to study the sample’s detailed atomic or molecular structure at synchrotrons. High frame rate AdvaPIX QUAD is specially designed for combined Wide Angle X-ray Scattering (WAXS) and Small Angle X-ray Scattering (SAXS). The open space in the center of the camera allows the X-ray beam to pass through the camera, eliminating the need to use a beam stop in front of the camera.


Achieve precise thermal neutron imaging with the dvaPIX camera’s ultra-high resolution.

AdvaPIX camera with a detector coated by a thin film of LiF can achieve ultra-high spatial resolution for thermal neutron imaging. The camera offers a sigma of Point-Spread-Function spatial resolution of up to 2.5 µm. The camera’s field of view is 14×14 mm, giving a maximum resolution of 6.5 MPix.

The camera has a Silicon sensor with a neutron conversion layer of 6LiF. Thermal neutrons are captured by 6Li, which produces Alpha particles and tritons. These heavily charged particles are then detected in the Silicon sensor. The ultra-high spatial resolution is achieved by processing individual neutron hits while considering charge collection in the sensor. All this advanced processing is implemented in the camera software, which is simple to use.
