The wire insulation takes
10 weeks
when CGP receive the goods.
Now about 300 m
NbTi
wire
has been
sent
to CERN for
testing
bond strength
of the
insulation.
Slide5Advancement of FormersExternal tube
The factory is preparing red and blue color for the anodization of external tube.
5
Red color is ok.
Blue color is till in color matching
Slide6Advancement of Yoke Yoke (KEYE)2nd
Yoke Steel → 40 tons yoke steel has been received. However most of the yoke steel are
being oxidized.The yoke used wire cutting. However the precision is not enough for key slot(0.02mm). The factory want to change into CNC
milling machine. 6
