TI - A Concept for a High-field Helical Solenoid J2 - Proc. of IPAC2015, Richmond, VA, USA, May 3-8, 2015 C1 - Richmond, VA, USA T2 - International Particle Accelerator Conference T3 - 6 LA - english AB - Helical cooling channels have been proposed for highly efficient 6D muon cooling to produce the required helical solenoidal, dipole, and gradient field components. The channel is divided into sections, each subsequent section with higher field. Simulations have shown that for the high-field sections the use of Nb3Sn superconductor is needed. A continuous winding method and novel stainless steel collaring system has been developed for use in the high field section of a helical cooling channel. Each collar layer is identical, for ease of fabrication, and assembled by both flipping and rotating the subsequent layers. Mechanical and magnetic simulations were performed using a combination of ANSYS and OPERA. The winding and collaring method has been demonstrated on a four coil prototype using a Nb3Sn Rutherford cable. Details of the mechanical design, magnetic modeling, and winding method are presented.
