Abstract
An NMR measuring system with an NMR probehead has at least one cooling device () generating a vibration spectrum of individual selective frequencies. The cooling device is mechanically connected to a vibration absorber () having an oscillating mass element (), whose resonance frequency is adjusted to the vibration frequency of the cooling device and/or to one of its harmonics. The cooling device has a cooling head which is thermally connected to an NMR resonator of the probehead via a flexible mechanical element. A vacuum housing of the probehead is designed in two parts which are mechanically connected via at least one damping element (-). The lower part and the upper part of the vacuum housing are additionally mechanically flexibly connected to each other in a vacuum-tight fashion via a corrugated bellows (). The system minimizes sidebands in NMR spectra.
