  In ADS Injector I, there are six superconducting magnets in each cryomodule.
Each superconducting magnet contains a solenoid magnet, a horizontal dipole
corrector (HDC) and a vertical dipole corrector (VDC). Six current leads will
be required for powering the electrical circuits, from room temperature to the
2.1K liquid helium bath. Two leads carry 100A current for the solenoid magnet
while the other four carry 12A for the HDC and the VDC. This paper presents the
principle for current lead optimization, which includes the cooling methods,
the choice of material and structure, and the issues for current lead
integration as well.
