The LMB’s NMR facility is home to five of the LMB’s seven NMR spectrometers, and is also currently hosting a spectrometer for our future neighbours AstraZeneca while their building is being completed. This photograph for day 232 of #LMB365 shows our highest strength, 800 MHz, magnet which is typically used for studying larger protein systems or when the most sensitivity is required. Liquid helium maintains the magnetic coils of the spectrometer at a chilly 1.9 kelvin: removing all electrical resistance, which allows the charge to remain indefinitely without a power source. Many people do not realise that we can’t simply switch off our magnets once energised.
