we are seeing upward frequency drift of 1000hz on philps F2000 magnet post rampup and shim.its already 48hours since rampup and shim and frequency has gone up by almost 1.8k.any advise will be helful
Please send me an assessment of your system, some photos of you ramp kit, and photo of your magnetometer as well as your shim document. I have seen several DOWNWARD drifts, but this would be the first UPWARD drifts I have seen. marshall@imagetechnology.net

I recommend recording the room temperature and humidity over time versus the frequency shift. 1K does not sound abnormal. 10K is abnormal.
