A method of setting up an NMR spectrometer having: a superconducting magnet system for applying a static magnetic field H 0 to a sample; an NMR probe for magnetically exciting nuclei under investigation of the sample at the Larmor frequency corresponding to said static magnetic field H 0 by applying an RF magnetic field to the sample in a direction perpendicular to the static magnetic field H 0; a detection coil made of a type-2 superconducting material, incorporated in the NMR probe and configured for detecting an NMR signal at the Larmor frequency emanating from the magnetically excited nuclei under investigation; and a cryogenic cooling system for cryogenically cooling the detection coil, thereby enhancing the Q value of the coil, and reducing thermal noise, said method comprising the step of: setting an external magnetic field to H 0 + ΔH, where ΔH > 0, and applying said external magnetic field which is stronger than the ultimate target external static magnetic field strength H 0 by ΔH to the detection coil when the detection coil made of the superconducting material is still in a normal state, characterized in that the method further comprises the steps of: cooling the detection coil made of the superconducting material down to a temperature T 0 being lower than its critical temperature T c to bring the coil into a superconducting state while the external magnetic field H 0 + ΔH is applied to the detection coil; and lowering the external magnetic field from H 0 + ΔH to H 0 such that the applied external magnetic field is decreased by ΔH while the detection coil is kept in the superconducting state. a superconducting magnet system for applying a static magnetic field H 0 to a sample; an NMR probe for magnetically exciting nuclei under investigation of the sample at the Larmor frequency corresponding to said static magnetic field H 0 by applying an RF magnetic field to the sample in a direction perpendicular to the static magnetic field H 0; a detection coil made of a type-2 superconducting material, incorporated in the NMR probe and configured for detecting an NMR signal at the Larmor frequency emanating from the magnetically excited nuclei under investigation; and a cryogenic cooling system for cryogenically cooling the detection coil, thereby enhancing the Q value of the coil, and reducing thermal noise, said method comprising the step of: setting an external magnetic field to H 0 + ΔH, where ΔH > 0, and applying said external magnetic field which is stronger than the ultimate target external static magnetic field strength H 0 by ΔH to the detection coil when the detection coil made of the superconducting material is still in a normal state, characterized in that the method further comprises the steps of: cooling the detection coil made of the superconducting material down to a temperature T 0 being lower than its critical temperature T c to bring the coil into a superconducting state while the external magnetic field H 0 + ΔH is applied to the detection coil; and lowering the external magnetic field from H 0 + ΔH to H 0 such that the applied external magnetic field is decreased by ΔH while the detection coil is kept in the superconducting state. setting an external magnetic field to H 0 + ΔH, where ΔH > 0, and applying said external magnetic field which is stronger than the ultimate target external static magnetic field strength H 0 by ΔH to the detection coil when the detection coil made of the superconducting material is still in a normal state, cooling the detection coil made of the superconducting material down to a temperature T 0 being lower than its critical temperature T c to bring the coil into a superconducting state while the external magnetic field H 0 + ΔH is applied to the detection coil; and lowering the external magnetic field from H 0 + ΔH to H 0 such that the applied external magnetic field is decreased by ΔH while the detection coil is kept in the superconducting state.
