NIKA2 observing pools: the work behind.
NIKA2 has been permanently installed at the IRAM Pico Veleta 30m telescope since October 2015. After the first commissioning campaigns, NIKA2 is now open to the international community and has been used in many scientific observing pools. Although invisible to the final user, the complexity of the instrument requires a lot of careful work to get everything ready before each pool, starting from the cryostat cooldown to all the sanity checks and performance verifications that are paramount to assure the smooth running of the campaign and the quality of the recorded data. In my talk, I will describe this hidden work, and the way it is being handed over to the local personnel, with the aim of making NIKA2 an IRAM facility instrument.
