WAB heat test @ IYC

I'm in Mitaka but looking at thermometers.

After I set the input power from 2W to 1.3W yesterday, the temperature of the WAB has been getting down (Fig 1). As usual, the derivative is also calculated (Fig 2), and from this plot, it is still not in equilibrium even after 24 hours.

By the way, Kimura-san said that he repaired some parts for the cooling path around one of the duct shield at around 15:00 today JST; the one shows about 200K, while the other side shows 120-130K (Fig 3), and those for EYC shows 110-140K. Immediately after his work, K1:CRY-TEMPERATURE_IY_DS1_50KREFFRONTBAR started to reduce drastically (Fig 1 and 2, named "50Kbar"), while the duct shield itself is not so sensitive to this, but it seems also reducing. Let's see...
