New SciFi geometry v6.4 with updated C-frames
Updated v6.4 geometry for the SciFi. Changes with respect to v6.3 are:
- the dimensions and the mass of the C-frame are updated according to the latest designs (doubles the total mass of the C-frame wrt v6.3),
- bug fix in the positioning of the v layer, which caused a shift of 0.2 mm in the z direction from the nominal position.
There is an internal note (LHCb-INT-2017-027) in circulation that details the SciFi geometry. Temporarily it can be found here. This note will be released as soon as the global tag is available.
