Helium boil off

WebLiquid helium is necessary to cool the supra conducting magnets. NMR spectrometers feature very special boil-off dispersion characteristics. During normal operation, the gas emission coming from helium boil-off is only minimal. When the dewar is refilled, however, helium boil-off skyrockets and needs to be handled. http://www2.chem.uic.edu/nmr/downloads/BASHCD10/pdf/z31408.pdf
