| '''New strategy for editing the page: With the log of Saturday it appeared that the ANTI-CHRONOLOGICAL ORDER makes it difficult to follow updates and discussions since the latest entry may answer an older entry possibly difficult to find for someone not following the updates in real time. So we go back to CHRONOLOGICAL ORDER and use the table of content with hyper links TO AVOID ENDLESS SCROLL DOWNS :)''' | ''Strategy for editing the page: the anti-chronological order makes it difficult to follow updates and discussions for someone not following the updates in real time when the latest entry answers an older entry possibly difficult to find.

| Cryocooler started | Cryocooler started. Unfortunately the 3He pumps makes very strong vibrations in the cabin possibly affecting GISMO observations; that was not a problem as long as the weather was to bad for observations, but the forecast was good for the night, so we stopped the pump in the evening. Hopefully the pump is not mandatory for the 1st phase of the cooling process. === Saturday 10/11 === The NIKA cooldown is not suffering from the pump stop. The inner parts of the cryostat are also cooling down in some way. At mid afternoon the cryostat is below 8K. However we can start the dilution only if the 3He pump is switched on. If the weather degrades again so much that the observations with GISMO are not possible any more we will switch on the pump, otherwise we have to wait until Tuesday. Alain and Juan have been testing the NIKA software remotely, sneaking the Elvin messages from the GISMO observations. |

Cryocooler started. Unfortunately the 3He pumps makes very strong vibrations in the cabin possibly affecting GISMO observations; that was not a problem as long as the weather was to bad for observations, but the forecast was good for the night, so we stopped the pump in the evening. Hopefully the pump is not mandatory for the 1st phase of the cooling process.
Saturday 10/11
The NIKA cooldown is not suffering from the pump stop. The inner parts of the cryostat are also cooling down in some way. At mid afternoon the cryostat is below 8K. However we can start the dilution only if the 3He pump is switched on. If the weather degrades again so much that the observations with GISMO are not possible any more we will switch on the pump, otherwise we have to wait until Tuesday.
