HEC2 C wheel rotated
November 2002
Pictures sent by Roy of the hadronic endcap calorimeter second wheel (HEC2 C) during rotation
in building 180 at CERN, 27 November 2002.
A few words of wisdom from Roy:
"The 'good news' is .... the HEC2 C Wheel has been rotated and is being
prepared for HV testing. There is no 'bad news'.
Once again, the procedure went very smoothly. There were a few creaks and
groans when the load was first lifted off the Support Structure, but once
stable, the rest of the operation was routine. The stiffening brace did its
job very well, and this can be seen in the photographs. With the brace in
place, the table deformation, of 2.8mm, was slightly less than with the HEC1
Wheel.
So, having now lifted and rotated the 90 tonne 'donut' successfully, we do
not expect any surprises during the remainder of the wheel assembly program."
