PrototypeMeasurement
Measurement Aim.
To assess if the production method proposed would produce
flanges accurately enough to allow for the production of a 15
flange 1π ball arrangement.
Single Flange Prototype made at Legnaro, and measured with a CMM
at Daresbury.3

Measurement Aim.
To assess if the production method proposed would
produce detector assemblies accurately enough to allow for the
production of a 15 flange 1π ball arrangement.
