Pre-industrialization activities related to CMS coil winding

The CMS coil is a large 4 layer superconducting solenoid involving the use of a new design reinforced conductor. In order to understand the feasibility of the coil manufacture using the inner winding technique for this particular conductor, the CMS Collaboration has developed a pre-industrialization activity. The main objectives were: (1) study of the methods for winding a coil using a stiff conductor; (2) design, construction and testing of a prototype winding line; and (3) construction of a model for the fine tuning of the required operation and procedures. The activities, carried out in cooperation with industry, were successfully completed, giving basic information for the necessary tool and methods to be used for the coil winding.
