UELR-8-2D

Safety first:

  • – the ionization chamber controller generates a radiation shutdown signal after achieving the required dose;
  • – the accelerator has interlock inputs to receive signals from the security systems of the X-ray chamber in accordance with the requirements of Sanitary Rules and Regulations;
  • – the accelerator system status monitoring and fault diagnosis can be carried out remotely via remote communication lines;
  • – local radiation protection of the emitter reduces the dose rate at a distance of 1 m from the body at least 10 -4 times outside the working area with respect to the dose rate on the axis of the accelerator;
  • – the presence of local radiation shielding allows to optimize the radiation protection of the x-ray chamber, reducing its thickness outside the working area, and also improves image quality, reducing the illumination of the film (detector) by spurious radiation.

Basic features:

  • – type of ionizing radiation: bremsstrahlung (brake radiation)
  • – typical use: nuclear, chemical, shipbuilding, rocket engineering, oil, gas, and other industries for non-destructive testing of large objects, including detection and identification of shells, cracks, non-proofing, cavities, foreign inclusions, material heterogeneity, etc.
  • – thickness of controlled objects in steel equivalent: up to 500 mm
  • – the emitter unit is equipped with a laser guidance system

Advanced control:

  • – the operator controls the operation of the accelerator using the control panel, which allows for automatic activation of the accelerator, selects the value of energy, dose rate, required dose, and radiation;
  • – along with the small size of the focal beam on the target, the possibility of independent regulation of the energy of accelerated electrons and the dose rate of bremsstrahlung makes possible to choose the optimal radiation parameters depending on the characteristics of the controlled object and to obtain high-quality images with high spatial resolution;
  • – the ionization chamber built into the emitter allows pulse-to-pulse control of the dose rate and the accumulated dose;
  • – accelerator systems are monitored by specialized controllers located in the emitter housing and connected to the host computer via ethernet.

Robust yet customizable design

  • – the radiation source has a significant operational life
  • – the accelerating structure, the electron gun and the brake target are delivered in sealed form, no need of vacuum pumping
  • – based on a single technological platform enabling the development of digital radiography systems using flat panel detectors or other recording means, as well as industrial tomography systems
  • – same technology is used for accelerators with a maximum energy of 15 MeV and a maximum dose rate of 120 Gy/min
