High Energy X-Ray LIMINACS

PMB Alcen:

Located near Aix-en-Provence, in France, PMB Alcen is a 130 employee SME. With a strong expertise in brazing, the company designs and manufactures complex mechanical assemblies and components (ceramic-metal, radio-frequency….), linear particle accelerators and cyclotrons. PMB is part of the industrial group ALCEN working in the fields of Defence & Security, Energy, Medical & Healthcare, Aeronautics & Space and large scientific instruments.

Features include:

  • Integration of Digital Flat Panel (DDA) – Shielding and fixture bracketry.
  • LINAC, object and DDA manipulators.
  • Software suite – Monitoring, 3D reconstruction and volume visualization.

Applications for LINAC’s include:

  • Aerospace (space flight components, aircraft structure, solid rocket fuel tanks).
  • Defence (missiles, turbine blade, casting inspection).
  • Research
  • Industry (casting inspection, high-value metal detection).

Reduced Focal Spot:

As the PMB LINAC can be manufactured with a reduced focal spot down to 0.7mm, depending on the measurement method, this means the combination of LINAC and imaging system can produce greater image resolution, making it easier for the operator to detect even the smallest defects. As the reduced focal spot allows the object to be closer to the source, by the inverse square law, a higher dose rate can be achieved.

Nominal focal spot (1) and reduced focal spot (2) measurements with IQI Duplex (EN 462-5) and a magnification factor x3.
