The on-axis fields are calculated at the critical current densities of the NbTi and Nb3Sn superconducting coils at 4.2 K. The parametrized on-axis fields for the period range are expressed in terms of the period and inner radius of the helical coils. The corresponding critical current densities and coil maximum fields are also included. The parameterization procedures are described in detail and some field deviations are discussed.
