Hannibal vapour cell replaced at Las Campanas in 2018 October

Hale, Steven J. (2018) Hannibal vapour cell replaced at Las Campanas in 2018 October. Technical Report. Birmingham Solar Oscillations Network.



The toroidal transformer power supply in the weather module failed and was replaced. The transformer failure caused the supply fuse for the main electronics rack to blow, additionally removing power from all other modules including the thermocouple sensor amplifiers within the Hannibal spectrometer. Whilst the sensors were without power, the vapour cell oven became overheated and caused damage to the vapour cell. The cell was replaced with the last available spare. The two UPS devices were tested and both found to require new batteries.
