Neutron Chopper Drive Systems

The world’s leading neutron scattering facilities require unique and dependable  instruments. These instruments must always be online to enable visiting scientists to make new  material science discoveries
Neutron chopper
Our customers have used SKF’s neutron chopper drive systems to enable:
  • New payload design possibilities through higher speed rotation and increased bearing capacity
  • Contamination-free beam guides due to elimination of lubricants
  • Higher neutron flux densities at the sample with vacuum operation

Some of the prime benefits of SKF neutron chopper drive systems are:

  • High instrument reliability enabled by magnetic bearing technology
  • Contact free rotation with no wear and minimal maintenance
  • Faster commissioning and simplified monitoring of system health using MBScope and SKF @ptitude Observer software tools 
  • Validated to ISO standards for machine vibration and stability
An SKF neutron chopper drive system is a plug and play solution that includes a controller, spindle, and cabling.

Magnetic Bearing Controller

Magnetic bearing controller
The controller is responsible for both the magnetic bearings and the motor control. It provides precise phase control and communicates with the instrument’s master control system. SKF’s latest offering is built upon our 5th generation technology which has been refined across multiple industries.


spidle neutron chopper
SKF offers a number of spindle types for neutron choppers including disk, Fermi, and T0 - all designed to be compatible with a wide range of payloads. SKF works with neutron facilities and payload providers to integrate mechanical, electronic, and communication systems.
