- Compensation coils can be used to improve the homogeneity at the centre of the field by reducing the rate at which the field drops at the end of the coils
- Shim coils are used to remove residual field gradients, and may be wired in series with the main coils to give a basic level of correction ('series shims') or independently to give finer adjustment ('independent shims' with their own ISS10 shim power supply)
- Modulation and gradient coils can be fitted into the bore of the magnet to provide a modulated (typically sinusoidal ac) magnetic field or a field gradient across the sample space. A single coils offers both options, and is powered via a separate set of current leads
- Cancellation coils may be fitted above and/or below a magnet to give a low field region close to the centre of field, frequently used with dilution refrigerator systems
Further magnet options, vector rotate, split pairs and more are available, please see our Custom & Speciality page or alternatively contact us for details.
