WAB in EYC is in Saving-mode!

Yano, Tanaka, Simon

after we brought out the cooling bar, we continued with finishing the WAB installation:

  • we slightly reset the traverser as we discovered that one of the bars were a little bit too far away from the duct
  • Then, we inserted the WAB after the usual procedure carefully inside the duct until the end-stopper of the traverser was reached. We had to slightly correct the horizontal position (~1mm) of the hooked WAB to insert it with reasonable gap to the duct opening
  • When lowered down, the WAB stood tall and solid on the feet immediately. We measured its balance and it looks quite good (see pictures)
  • While still hooked, we set the baffle protectors on the +Y side and covered it by an Al foil

We discovered that there is a little bit more a gap between upper and lower duct-edge and the baffle than at the sides (Δ ~ 5 - 7mm)... we don't know why this happens. Maybe the duct opening is elliptical?
Anyway, the WAB is set in saving-mode and ready for the payload installation!
