MA-260S Mossbauer Velocity Transducer
MA-260S is the standard model of the WissEl velocity transducer line. It is equipped with strong NdFeB and SmCo5 magnets, which provide a high power and have practically no magnetic fringe fields at the site of an attached Mossbauer source. The MA-260S is a versatile instrument for all kinds of Mossbauer experiments.
Features
- Moving coil principle with permanent magnets
- High linearity and stability
- No magnetic fringe fields at source position
- Suitable for standard Mossbauer experiments
