ADC has developed the most complete set of high-precision slits for Neutron applications.
ADC has been a leading supplier of slits to the synchrotron and neutron source scientific community for over 18 years.
Many of our slits have been in operation nearly that long in facilities around the world. Our standard slits run the range from in-air monochrome beam to UHV high heat load white beam.
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).
Air or Vacuum
Customized to Customer Specifications; size, blade material, etc.
Example Custom Slits
LANL SMART Instrument 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 made from 5mm Thick Boron Carbide; 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.
ANSTO PELICAN Instrument Slits
ADC custom designed and built two slits for PELICAN instrument located at ANSTO Neutron facility. The blades are mounted on preloaded carriages that are guided by miniature ball guide rails. The blades are fully scannable. A Kubler Absolute Multiturn Rotary Encoder is used to track the position of the blades. The limits are lever style snap-action switches. Connectors arecircular MIL Spec Metal Connectors as specified by the customer.

In co-operation with CHESS at Cornell, we have developed the very best blade polishing available in the industry today.
We have built an extended family of standard slits in application categories though continuous improvement in our designs.
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.
