4. Electric Motor for the Beam Wire Scanners Requirements for new motor selection: New motor will be the same in beam wire scanners for PS/SPS/PSB so should provide torque sufficient to accelerate the wire to linear speed 20 m/s in both configurations: 182.5 mm (PS/SPS) and 150 mm (PSB) mm forks; The desired motor should be based on the standard market solution which will be available for many years; The rotor will be located in vacuum and must be vacuum compatible; the use of any glue, other adhesives or insulating materials is not possible. Solid core rotor should be used. The minimum motor air gap should be large enough to allow the introduction of a low magnetic permeability stainless steel wall (vacuum chamber) with the thickness of 0.3 mm. The moment of inertia of the rotor should be minimized in order to reduce the required acceleration torque; Features for mounting the rotor on the shaft (key-slots, holes, etc.) should be considered in the design; The whole motor must withstand an ionizing radiation of 1 kGy/year. Once the motor is selected and approved the detailed design of the prototype for PSB can be launched as well as design for series production for PS/SPS/PSB The motor currently used is obsolete and will not be available for purchasing
