Today we set the oplev again, and SUM was 8000.
When 8K radiation shield was ~4,50K, the frost of the view port vanished yesterday.
Therefore we kept to stop one of the 4K cryocooler for the radiation shield(Ref.3), and we started the remaining 4K cryocooler. (13:19)
We hope that 8K radiation shield temperature will become ~50K.
Now 8K radiation shield temperature is ~55K. (18:46)
