10 K Closed Cycle Refrigerator Systems
Application Specific Models - Vibrating Sample Magnetometry (CCS-7xx series)
Designed for vibrating sample magnetometry experiments, this system locates the sample in an isothermal zone of static helium gas.
Designed for vibrating sample magnetometry experiments, this system locates the sample in an isothermal zone of static helium gas. The design incorporates features and materials to shield the sample and pick-up coil region from spurious eddy currents, which could reduce the sensitivity of the magnetometer when sweeping the field. The magnetometer sample drive is mechanically isolated from coldhead vibrations, and the sample is top loading for quick sample exchange. Designs exist for most commercial electromagnets and ensure that the sample is located at the exact center of field.
