Facility to coat the SPS magnets with carbon

Objective: coat at least 90% of the SPS with a carbon thin film with low secondary electron emission in order to mitigate electron cloud. Objects to coat: dipoles (MBB+MBA = 70%), Quadrupoles (QD+QF = 10%), LSS (10%), eventually SSS (10%). The pumping port shields shall also be coated.
