ULTRAFAST X-RAY SHUTTERS

Shutter assemblies and complete shutter solutions for fast and accurate radiation blockage

Innospexion has developed ultrafast X-ray shutter systems, integrated with X-ray cabinet, X-ray source, and mechanics for the positioning of detector boards for measurement, as well as a PLC-based control system and user interfaces. The need for these ultrafast X-ray shutter systems is typically for quality control of the response time of radiation detectors and other conformity parameters in the manufacturing of X-ray imaging or measurement detectors.

THE VALUE OF LOW-ENERGY X-RAY TECHNOLOGY:

  • reducing loss and making best use of raw materials
  • better product classification and a better product price
  • avoiding customer complaints
  • a robust, reliable, and safe inspection technology
  • hygienic design guidelines

In 2017, we developed an ultrafast X-ray shutter (1 ms). Shutters are available up to 300 kVp X-ray radiation. Neutron shutters can be developed relative to specifications, as tailored versions.

OBJECTIVE

InnospeXion has developed, produced and installed a number of shutter systems for X-ray beam closure, since 2002. In 2014, a very fast shutter with opening or closing time less than 10 ms was developed. In 2017, this was followed by the ultrafast (1 ms) shutter. Shutters are available up to 300 kVp X-ray radiation. Neutron shutters can be developed relative to specifications (tailored versions).

InnospeXion has provided the shutter systems integrated with X-ray cabinet, X-ray source, and mechanics for the positioning of detector boards for measurement, as well as a PLC-based control system and user interfaces.

SOLUTION

The shutter is driven by a dedicated servo motor and moves a lead disc (optionally a Boron containing disc for neutron usage) with a mass of 800 g to open/close a window of 6 x 9 cm. The shutter is fitted with numerous laser sensors to enable that access door can be opened with the beam on. The shutter is entirely controlled from the PLC. 

The PLC may be externally controlled from a PC or other control hardware. The shutter is designed for mounting close to the X-ray source window but can be configured for use in e.g. a neutron or other X-ray source beam configuration. The electromechanical assembly is made of aluminum, and measures approximately 300 x 300 x 200 mm.

The shutter speed has been validated during the design phase and confirmed by positioning of fast read out radiation sensitive area detectors in the beam. By profiling, the shutter movement can be traced, which has confirmed an opening or closing speed of less than 1 ms. Opening time may be as long as requested.
