HCS1 Three-Axis Helmholtz Coil System
System consisting of three pairs of coils, a drive amplifier, and a control unit. Coils generate a magnetic field up to 500μT for a DC field and up to 100μT for a 5kHz field.
This system generates a magnetic field of up to 500μT for a DC field and up to 100μT for a 5kHz field. The coils, minimum diameter 500mm, produce a 0.1% homogeneous field of 260 cubic centimetres and a mounting table is provided to hold the test item inside the homogeneity volume. A 1-meter diameter version will be available later in 2014.
The system consists of up to three pairs of coils, one for each axis and available in any combination, and a drive amplifier that runs from a standard mains socket. A control unit (CU1) can also be supplied that allows the user to set the field, set any DC compensation as required and receive feedback from the coils. The CU1 includes a National Instruments® PXI system and operates using LabVIEW-based software.
