Abstract:
In the framework of magnetic measurements in particle accelerators, the problem of the driftThe gradual loss of an instrument's accuracy. NMR teslameters drift because their time base drifts; this can be easily checked and... More due to integration of a voltage offset causes a lack of stability, which is inadequate for long-term measurements. In this paper, a new approach for the modelling and correction of long-term driftThe gradual loss of an instrument's accuracy. NMR teslameters drift because their time base drifts; this can be easily checked and... More in integrators is discussed. In particular, a feed-forward driftThe gradual loss of an instrument's accuracy. NMR teslameters drift because their time base drifts; this can be easily checked and... More correction method has been developed analytically and tested using experimental data taken from an existing real-time magnetic measurement system. Among all the sensors, NMRNuclear Magnetic Resonance. A resonance phenomenon seen when you irradiate a sample in a magnetic field with an RF field....

More (10 −6 ) and the Metrolab PT2026 NMR teslameter has been tested successfully as a novel kind of quasi-DC field marker. The combination of feed-forward correction and PT2026 as a marker will allow the future real-time magnetic measurement systems to meet the very strict specification of 1 μT field stability over durations of the order of minutes. In certain cases, such as in ELENA, this method offers a way to reduce by three orders of magnitudeThe magnetic field is a vector quantity. We may be interested in its individual components or its total magnitude. More the drift-induced field error with respect to the existing system.
