| Abstract Title: |
Stabilization of an NMR elctromagnet at low cost |
| Abstract: |
The current supplied by our unstabilized power supply varies approximately 4 parts in 10^-4 limiting its use for NMR experiments. We present details and results of a method to relatively easily externally stabilize a 12in, 1T electromagnet powered with a unstabilized power supply. The magnet current is measured with a high power precision resistor to feedback stabilze the current with an external opamp circuit. The power supply is not modified. |
