X-Ray Calibration Systems

Gemini specialize in the supply of Secondary Standard Dosimetry Systems. We have designed, manufactured and commissioned a significant number of Gamma, Neutron, and X-ray Calibration Systems. As well as numerous upgrades, to both mechanical and control systems.

Control Unit
The Exposure unit is controlled via a Windows based software system, its main features include:

  • Full control of X, Y, Z and rotational axes.
  • Full control of rotary neutron source cassette.
  • Certificate issued for each instrument calibrated.
  • In-cell control of video equipment and screen grab display of camera in top corner of monitor.
  • Radiological status supplied on monitor screen; full control of warning lights, audible alarm and e-stops.

Video Systems
  • Multi zoom camera lens for clear visual image of calibration instrument.
  • Pan/tilt unit attached to colour camera for accurate positioning.
  • Adjustable stand.
  • In-cell LCD mini monitor attached to trolley.
  • Controller unit situated in control room to fully control pan/tilt, zoom and focus of camera.

X-Ray Exposure unit

The X-ray set is made up of a shielded enclosure, containing, an X-ray tube, Filter wheel, and X-ray shutter. The X-ray tube produces a beam of X-rays centred along the X axis. The filter wheel is located within the shielding for automatically selecting the different strengths of exposure. The X-ray shutter mechanism is fail-safe and will automatically drop and return to a safe position if the power is lost or one of the safety interlocks is activated.

Track & Trolley unit
  • AI Alloy construction using channel, angle and ground plate.
  • Precision linear rails and bearings used on X, Y and Z axes.
  • X axis driven via a linear actuator using a stepper motor/gearbox arrangement.
  • Y axis driven via a lead screw using a stepper motor.
  • Z axis raised and lowered via a screw jack using a stepper motor/gearbox arrangement.
  • The rotational axis is driven via a precision rotary table.
  • Energy chain used on X and Y axes for tidy/stress free transportation of cables.
  • Lengths, widths and heights can be modified to meet the requirements of the customer.
