Shim Power Supply

The Bridge12 Shim Power Supply (SPS) is an 8 channel, bi-polar, programmable power supply. The Bridge12 SPS can be used to drive active, electrical shims used in NMR/DNP spectroscopy to increase the field homogeneity.
Improved homogeneity leads to higher sensitivity

Improved homogeneity leads to higher sensitivity

Active shims are commonly used in (high-field) NMR spectroscopy to improve the magnetic field homogeneity. However, shimming EPR magnets is not very common, albeit its benefits.

The Bridge12 SPS

The Bridge12 SPS

The Bridge12 Shim Power Supply (SPS) is a compact bi-polar power supply. The system is configured to have a total of 8 independent channels, each capable to supply a maximum current of +/- 1.5 A at a resolution of 16 bits.

Remote Control

Remote Control

Controlling the Bridge12 SPS is accomplished through a serial interface (serial over USB). Optimized shim values can be saved in the memory of the micro processor. A Python Package is available for download to control the Bridge12 SPS.
