ANSTO SANS Instrument Vacuum Slits

ADC custom designed and built two slits for SANS Instrument  located at ANSTO Neutron facility.  The ANSTO Neutron Beam Slit is a standard XY Slit.  This slit uses a single NEMA 17 motor coupled to a screw for each blade to open and close the aperture.  The blades are mounted on preloaded carriages that are guided by miniature ball guide rails.  The blades are made from 5mm Thick Boron Carbide.  The blades are fully scannable and the  maximum aperture size is 70mm x 115mm.  A Kubler Absolute Multiturn Rotary Encoder is used to track the position of the blades.  The limits are lever style snap-action switches.  Connectors will be circular MIL Spec Metal Connectors as specified by the customer. This slit has been designed for use in a rough vacuum environment.

 

ADC has developed the most complete set of high-precision slits for Neutron applications. 

 

  • Micron precision
  • High radiation resistance components such as motors, brake, and encoders
  • Blade material;
    • Cadmium, Boron Nitride, Boron Carbide and/or composite structure consisting of several materials,
  • Blades can go "past closed" without clashing (Overlapping/Zero beam).
  • Standard sizes:
    • (12.5 mm X 12.5 mm aperture)
    • (25 mm X 25 mm aperture)
    • (60 mm X 60 mm aperture)
    • (100 mm X 100 mm aperture)
    • (150 mm X 150 mm aperture)
  • Customized to Customer Specifications; size, blade material, etc.
  • Air or Vacuum

 

All of these slits use standard micro stepped stepper motors that could be controlled with a wide array of controllers/drivers available on the market.  We now do 100% inspection on all our slits blades being sold.  For a copy of the report please contact ADC.
