Analytical field calculation of helical dipole magnets for RHIC

Name: Work Video:
Duration: 3 min 30 s
Description: The analytical expression for the magnetic field of helical coils is presented. In particular, the multipole coefficients are introduced for helical dipole magnets, which are essential components of Siberian Snakes and spin rotators for polarized proton acceleration at RHIC. In addition, the comparison analytical and numerical calculations is presented for simple helical dipole magnets.
