| Research Abstract |
For precision mass measurements of unstable nuclei using a multi-reflection time-of-flight mass spectrograph, ultra stable high voltage supplies are the essential prerequisites. We have developed such high voltage supplies using precision 24-bit ADC, low TC resisters and PID feedback system. The long-term stability of the high voltages was as slow as 5 mVrms for 1 kV supplies.
